The effect of beet curly top virus on growth and phytochemical constituents of coriander (Coriandrum sativum L.)

Leaves and seeds of coriander (Coriandrum sativum L.) are edible and have been used for culinary and medicinal purposes. The present study was conducted to investigate the effect of the beet curly top virus-sever on the physical and chemical properties of coriander leaves. Plants were inoculated at the three-five leaf stage with the infectious clone of the virus, and for mock inoculation, plants were treated with Agrobacterium tumefaciens containing binary vectors without virus sequence. Infected plants had a reduction in height (35 %) and in fresh and dry mass (21 and 30 %) respectively. In addition, in plants with high infestation intensity, flowering stems did not form, and seed production stopped completely. The total content of flavonoids, phenolic, and vitamin C decreased in the leaves of infected plants. The essential oil content did not significantly differ between the two treatments. Analysis of GC and GC–MS showed that the production of alcoholic compounds (33.02–36.03 %) and estragole (11.35–13.27 %) as a phenyl propene compound were reduced in essential oils of infected plants, but terpenoids (3.5–2.13 %) and aldehydes (35.9–40.68 %) were increased in their essential oils. n-tetradecanol, 2E-dodecenal, estragole, 2E-decenal, decanal, dodecanal, tetradecanal, and 2E-decenyl acetate were the main identified essential oil compound in both treatments. Virus infection changed the quality and quantity of chemical compounds; therefore, it is probable that the medicinal and culinary quality of coriander would be affected. Due to these chemical changes and, more importantly, the severe reduction in seed production of infected plants, it is recommended to investigate and evaluate the resistance of commercial cultivars and domestic coriander genotypes to the virus.

Formulation Containing Phytosomes of Crocin-Rich Extract from Nyctanthes arbor-tristis and Petroselinic Acid from Coriandrum sativum seeds Exhibits Sunscreen and Moisturizing Effects

Background: Orange coloured tubular calyx of Nyctanthes arbor-tristis can be utilized as a substitute for saffron due to the presence of crocin, an apocarotenoid, which can act as a sun-screen agent. Petroselinic acid is reported to have a moisturizing effect on the skin. Objective: To utilize the tubular calyx of Nyctanthes arbor- tristis as an economical source of crocin and Coriandrum sativum seed oil as a source of petroselinic acid for the development of a stable phytosomal gel formulation and to evaluate its sunscreen and moisturizing activities. Methodology: Phytosomes of standardized crocin-rich extract and petroselinic acid were prepared separately by lipid film hydration technique. The phytosomes were then incorporated into a gel base prepared from dehydroxanthan gum, and it was evaluated for in-vitro sunscreen activity by using Mansur’s equation. Moisturizing effect of the phytosomal gel was evaluated on 10 healthy female volunteers with their informed consent, and the water content of the stratum corneum was measured by using a Digital Moisture detector pen before and 5 hours later the application of the gel. Results: Mean initial moisture content of the skin was found to be 30.08 %, which was signifi-cantly (P < 0.05) raised to 45.59% at the end of 5 hours. Sun Protection Factor was found to be 15.09 and with a Boot Star rating of 2. Conclusion: Entrapping the phytoconstituents in vesicles increased stability, and the formulation was found to have moderate protection and a good moisturizing effect on the skin.

Garbage to Gains: The role of biochar in sustainable soil quality improvement, arsenic remediation, and crop yield enhancement

Threats of soil quality deterioration and metal pollution have inflicted several parts of the world, apart from the need for surplus crop production. The investigation used biochar prepared from waste biomasses such as wheat and rice straw, kitchen waste, leaf litter, Lantana camara, orange peel, and walnut shell to improve soil quality, reduce As pollution, and enhance plant growth. Biochars were amended at doses of 0%, 2.5%, 5%, and 7.5% and conditioned for 3 months. At a 7.5% dose, the maximum improvements in cation exchange capacity (a 62% increase), anion exchange capacity (a two-fold increase), bulk density (a 31% decrease), porosity (a 32% increase), water holding capacity (an 86% increase), soil respiration (a 32% increase), total carbon (a two-and-a-half-fold increase), total nitrogen (an eleven-fold increase), total phosphorus (3 times rise), total potassium (a two-and-a-half-fold increase), mobile As (a 38% decrease), leachable As (a 53% decrease), and bio-available As (a 56% decrease) were observed. Further, pot experiments revealed augmented biomass growth (61% and 177%), increased length (71% and 209%), and decreased As accumulation (56% and 55%) in the above-ground parts of Bengal gram and coriander plants, respectively. Therefore, the application of biochar was found to enhance the physico-chemical properties of soil, reduce As contamination levels, and improve crop growth. The study recommends using waste biomasses to prepare eco-friendly biochars, which could contribute to advancing sustainable agriculture and the circular economy.

Effect of different drying methods on phenolic content, antioxidant, antidiabetic, anti-obesity, and inhibition kinetic properties of selective green leafy vegetables

Abstract. Maser WH, Karnjanapratum S, Kingwascharapong P, Venkatachalam K, Ali AMM, Bavisetty SCB. 2023. Effect of different drying methods on phenolic content, antioxidant, antidiabetic, anti-obesity, and inhibition kinetic properties of selective green leafy vegetables. Biodiversitas 24: 4896-4909. The present study assessed the impact of dehydration drying, oven drying, and freeze drying on Total Phenolic Content (TPC), antioxidant activities (DPPH, metal chelating, and FRAP), and the inhibition activity of a-amylase, a-glucosidase, and lipase in selected green leafy vegetables, namely celery (Apium graveolens L.), coriander (Coriandrum sativum L.), parsley (Petroselinum crispum (Mill.) Fuss), and spring onion (Allium cepa L.). FTIR analysis was conducted to examine the functional groups, GC-MS was utilized to characterize the compounds, and a kinetic study of a-glucosidase inhibition was undertaken to assess its inhibitory mode as an antidiabetic agent. Freeze drying exhibited the highest extraction yield (17.89% to 26.15%). However, freeze-drying showed lower drying efficiency, TPC, and bioactivities. Oven drying showed the highest bioactivities, including antioxidant and enzyme inhibitory activities. Spring onion demonstrated the highest bioactivity with dehydration drying, particularly in a-glucosidase inhibitory activity. The results notified that oven drying can be highly suitable for green leafy vegetables with thinner structures, facilitating an efficient drying process. On the other hand, dehydration drying is better suited for thicker green leafy vegetables with the appropriate heat pump intensity. The results for bioactivities were aligned with the observed inhibition mechanism, functional groups, and bioactive compounds in the samples analyzed via FTIR and GC-MS analysis. Therefore, selecting the drying method for a specific sample should consider its unique characteristics to ensure optimal bioactivity.

Investigating of Genetic Diversity of some Coriander (Coriandrum sativum L.) Landraces in for Phenological, Morphological and Agronomic Traits

Safety and efficacy of a feed additive consisting of an essential oil obtained from the fruit of Coriandrum sativum L. (coriander oil) (FEFANA asbl).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of an essential oil obtained from the fruit of Coriandrum sativum L. (coriander oil), when used as a sensory additive in feed for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the use of coriander oil is safe up to the maximum proposed use levels of 30 mg/kg complete feed for piglets, pigs for fattening, sows, veal calves (milk replacer), cattle for fattening, sheep, goats and horses, salmonids, dogs and ornamental fish. For the other species, the calculated safe concentrations in complete feed are: 14 mg/kg for chickens for fattening, 28 mg/kg for laying hens, 26 mg/kg for turkeys for fattening, 28 mg/kg for rabbits and 14 mg/kg for cats. These conclusions were extrapolated to physiologically related species. For any other species, the additive was considered safe at 14 mg/kg complete feed. The proposed conditions of use for veal calves (10 mg/kg) and ruminants, horses and dogs (5 mg/kg) were considered safe provided that the use in water for drinking alone or in combination with the use in feed should not exceed the daily amount that is considered safe when consumed via feed alone. No concerns for consumers and the environment were identified following the use of coriander oil up to the maximum proposed use level in feed. Coriander oil should be considered as irritant to skin and eyes and the respiratory tract and as a dermal and respiratory sensitiser. Since C. sativum and its preparations are recognised to flavour food and its function in feed would be essentially the same as that in food, no further demonstration of efficacy was considered necessary.

The nano mixture of ethanol extract ketumbar (Coriandrum sativum L.) seed and putri malu (Mimosa pudica L.) leaves potentially reduced blood glucose levels in hyperglycemia wistar rat

The formation of nano extracts can increase the bioactivity of a compound in the body. The purpose of this study was to determine the ability of a nano mixture of Coriandrum sativum L seed and ethanol extract of Mimosa pudica L leaves to reduce glucose levels in hyperglycemic rats, compared to an ethanolic extract mixture of Coriandrum sativum L seeds and Mimosa pudica L leaves. The size and zeta potential characterization of the ethanolic extract mixture of Coriandrum sativum L seed and Mimosa pudica L leaves was carried out using a Particle Size Analyzer (PSA). The results of characterization with PSA showed that the nanoparticle size of the ethanolic mixture of Coriandrum sativum L seeds and Mimosa pudica L leaves was 184.4 nm and the zeta potential value was -1.62 mV. The particle size obtained is in accordance with the herbal nano size, which is 50-300 nm. Identification of compounds in the ethanolic extract mixture of Coriandrum sativum L seed and Mimosa pudica L leaves by LC-MS/MS, found 7 compounds suspected of antihyperglycemia, namely phenylalanine, indole, 4-methoxy benzaldehyde, 2,5-dimethoxy benzaldehyde, apigenin, 2-flouren-9-ylidenemethyl-pyridine, and 5-Pentyl-1,3-benzenediol. The activity test results showed that the nano ethanol extract mixture of Coriandrum sativum L seed and Mimosa pudica L leaves was more effective in lowering blood glucose levels (79.29%) compared to the ethanolic extract mixture of Coriandrum sativum L seed and Mimosa pudica L leaves (50.88%).

Development and Detection of Antimicrobial Properties of Polyherbal Handwash

Many of the medications marketed as traditional herbal medicines have unquestionably been used for a very long time. Hands have always been the dominant source of transmission of infection to patients. Thus, encouraging "personal hygiene" is the main objective of developing a herbal hand wash. The current study's goal was to develop a formulation of polyherbal handwash employing methanolic extracts of dried leaves of Azadirachta indica, Ocimum gratissimum, and Coriandrum sativum. Other ingredients entailed lemon juice, aloe vera, lavender oil, HPMC, triethanolamine, sodium lauryl sulphate (SLS), glycerine, and methylparaben. Four batches of hand wash formulations were prepared, and each batch was tested for stability, appearance, colour, grittiness, pH, viscosity, foam height, and other physical characteristics. Using the agar well diffusion method, the anti-microbial effectiveness of the prepared polyherbal hand wash was tested on a variety of bacteria, including Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Pseudomonas aeroginosa, Salmonella typhi, Aspergillus niger, and Candida albicans. The results demonstrated that manufactured herbal handwash formulations, particularly F3, displayed a prominent zone of inhibition in comparison to standard commercial handwash, indicating that the extract of these phytoconstituents may be employed to manufacture handwash with antimicrobial properties. As a result, the research shows that the herbal handwash formulation is analogous to commercial handwash in reducing the amount of bacteria on hands and may be used as a replacement handwash made from natural sources without experiencing any undesirable effects.

Effect of Bacillus sp. application on the germination of coriander (Coriandrum sativum L.) under salt stress

Coriander (Coriandrum sativum L.), one of the annual herbaceous plants widely used as a medicinal and aromatic herb, is used as flavor and aroma, to treat digestive system diseases, as antipyretic, etc. Salinity, which is one of the soil quality index parameters, is one of the most important abiotic stress factors limiting the production of agricultural products. This study examined the effect of Bacillus sp. application on germination rate (%), germination speed (days), average daily germination (days), peak and germination values of coriander at different salt (NaCl) concentrations (0, 50, 100, 150, 200 mM). It was determined that the Bacillus sp. and salt application were significant at the level of 1% in the investigated parameters and that the bacterial application minimized the negative effects of increasing salt concentrations on the germination biology. The germination rate (67%), germination speed (8.4 days), average daily germination (4.5 days), peak (2.33%), and germination values (10.5%) were obtained. It was determined that no Bacillus sp. + 50 mM salt application provided the best germination values in coriander seeds.

The Effect of One-Year Seed Spaceflight Storage on Yield, Biochemical and Mineral Characteristics of Mature Leafy Vegetables Belonging to Brassicaceae, Apiaceae and Asteraceae Families

Spaceflight is known to produce genetic changes in seeds, usually accelerating aging, though species and varietal differences have been poorly investigated. Comparisons were carried out in terms of yield, biochemical characteristics and mineral composition between mature plants grown from seeds subjected to a one-year spaceflight, belonging to Brassicaceae (Brassica juncea and Eruca sativa), Apiaceae (Anethus graveolens, and Coriandrum sativum), and Asteraceae (Lactuca sativa, six cultivars) families, and non-treated control. Among the studied species, only Brassica juncea and Eruca sativa demonstrated a growth stimulation effect caused by seed spaceflight, while significant growth inhibition was recorded in Apiaceae plants and three cultivars of Lactuca sativa L. No differences in the total antioxidant activity (AOA), polyphenol and ascorbic acid content were detected between ‘space-treated’ and control plants. On the contrary, significant decrease in proline accumulation and increase in malonic dialdehyde and photosynthetic pigments levels were shown by Brassicaceae species. The effect of long-term seed spaceflight on the mineral composition of mature plants was reflected in the inhibition of accumulation of all 24 elements analyzed in Apiaceae plants, except for Se, whose concentration was higher in all ‘space-treated’ plants compared to the control. Spaceflight seed storage increased V levels in lettuce and decreased Na accumulation in all the investigated species. The results reveal species-dependent changes in the accumulation of macro-, micro- and toxic elements in Apiaceae, Brassicacea, and Asteraceae representatives due to spaceflight seed storage. The detected differences in plant elemental composition between ‘space’ treatment and control partly explain the corresponding yield gap and suggest a relationship between mineral status and adaptability. The highest beneficial effect of spaceflight seed storage on yield was recorded in Eruca sativa cultivar, Rusalochka.

Development of Novel Nano-Sized Imine Complexes Using Coriandrum sativum Extract: Structural Elucidation, Non-Isothermal Kinetic Study, Theoretical Investigation and Pharmaceutical Applications.

A new Schiff base (H2L) generated from sulfamethazine (SMT), as well as its novel micro- and nanocomplexes with Ni(II) and Cd(II) metal ions, have been synthesized. The proposed structures of all isolated solid compounds were identified with physicochemical, spectral, and thermal techniques. Molar conductance studies confirmed that the metal complexes are not electrolytic. The molecular geometry located at the central metal ion was found to be square planar for the NiL2 and tetrahedral for the CdL2 complexes. The kinetic and thermal parameters were obtained using the Coats and Redfern approach. Coriandrum sativum (CS) in ethanol was used to create the eco-friendly Ni and Cd nanocomplexes. The size of the obtained nanoparticles was examined using PXRD and TEM, and found to be in the sub-nano range (3.07-4.61 nm). Furthermore, the TEM micrograph demonstrated a uniform and homogeneous surface morphology. The chemistry of the prepared nanocomplexes was studied using TGA and TEM techniques. The effect of temperature on the prepared nanocomplexes' size revealed a decrease in size by heating. Furthermore, the nanocomplexes' antimicrobial and anticancer properties were evaluated. The outcomes demonstrated that the nanocomplexes exhibited better antimicrobial properties. Moreover, the antitumor results showed that after heating, the Ni nanocomplex exhibited a substantial antitumor activity (IC50 = 1.280 g/mL), which was higher than the activity of cis-platin (IC50 = 1.714 g/mL). Finally, molecular-docking studies were performed to understand the evaluated compounds' ability to bind to methionine adenosyl-transferases (PDB ID: 5A19) in liver cancer and COVID-19 main protease (PDB ID: 6lu7) cell-proteins. The findings reveal that [NiL2]·1.5H2O2 has a higher binding energy of -37.5 kcal/mol with (PDB ID: 5A19) cell protein.

Estimation of variability, heritability, and genetic advance among Ethiopian coriander (Coriandrum sativum L.) accessions

The objective of this study was to assess the extent of variability of yield and yield-related traits, heritability, and genetic advances among Ethiopian coriander accessions. The experiment was conducted at Kulumsa Agricultural Research Center, Southeast Ethiopia, during 2019- 2020 cropping seasons. Twenty-five Ethiopian coriander accessions were tested in a 5 x 5 simple lattice design with two replications; and data were collected on eight yield and yield-related traits. The combined analysis of variance revealed highly significant differences (P<0.01) between coriander accessions for each trait. The results showed a wide range of variability in all studied traits, indicating the potential for simultaneous improvement of yield and yield-related traits. The heritability (H2b) estimates ranged from low for seeds per umbellet and thousand seed weight to very high, for seed yield per hectare and number of umbels per plant in the first and second cropping season, respectively. The highest genetic advances as a percentage of the mean (GAM (%)) were observed for seed yield per plant, seed yield per hectare, and number of umbellets per umbel. These findings suggest that cultivar selection based on these traits with high H2b coupled with GAM (%) could enhance progeny performance and increase the productivity and profitability of coriander. Therefore, the results had practical implications for coriander breeders and farmers in Ethiopia and could contribute to the development and sustainable coriander farming practices. Further investigations are necessary to identify superior accessions with desirable processing qualities, assess the phenotypic and genotypic diversity among Ethiopian coriander accessions.

Management Zones Delineation, Correct and Incorrect Application Analysis in a Coriander Field Using Precision Agriculture, Soil Chemical, Granular and Hydraulic Analyses, Fuzzy k-Means Zoning, Factor Analysis and Geostatistics

The objective of our investigation was to study the various effects of correct and incorrect application of fuzziness exponent, initial parameterization and fuzzy classification algorithms modeling on homogeneous management zones (MZs) delineation of a Coriandrum sativum L. field by using precision agriculture, soil chemical, granular and hydraulic analyses, fuzzy k-means zoning algorithms with statistical measures like the introduced Percentage of Management Zones Spatial Agreement (PoMZSA) (%), factor and principal components analysis (PCA) and geostatistical nutrients GIS mapping. Results of the exploratory fuzzy analysis showed how different fuzziness exponents applied to different soil parameter groups can reveal better insights for determining whether a fuzzy classification is a correct or incorrect application for delineating fuzzy MZs. In all cases, the best results were achieved by using the optimal fuzziness exponent with the full number of parameters of each soil chemical, granular and hydraulic parameter group or the maximum extracted PCAs. In each case study where the factor analysis and PCA showed optimal MZs > 2, the results of the fuzzy PoMZSA clustering metric revealed low, medium and medium to high spatial agreement, which presented a statistically significant difference between the soil parameter datasets when an arbitrary or commonly used fuzziness exponent was used (e.g., φ = 1.30 or φ = 1.50). Soil sampling and laboratory analysis are tools of major significance for performing exploratory fuzzy analysis, and in addition, the FkM Xie and Benny’s index and the introduced fuzzy PoMZSA clustering metric are valuable tools for correctly delineating management zones.

Insects pollinating parsnip Pastinaca sativa l. (Apiaceae) in Moscow province

The purpose of the study was to test the ability of Pastinaca sativa , as one of the plants whose sap contains furanocoumarins, to attract the same types of insects as the most dangerous weed - Sosnowsky’s hogweed, which is widely spread in Russia. As a result, 46 species of pollinating insects from the orders Hymenoptera (3 species), Hemiptera (2 species), Coleoptera (10 species) and Diptera (31 species) have been recorded on P. sativa . Among the latter, representatives of Tachinidae (6 species), Anthomyiidae (6 species), Calliphoridae (4 species), and Syrphidae (4 species) predominated. About 50% of insects pollinating P. sativa are found on other species of umbrella plants, including native species Anthriscus sylvestris , Aegopodium podagraria , Angelica sylvestris ; on horticultural crops: Anethum graveolens , Petroselinum crispum , Carum carvi , Coriandrum sativum , Levisticum o cinale , and on the invasive hogweed Heracleum sosnowskyi . It was not possible to detect any preference of insects for yellow (parsnip, lovage, dill) or white (kupyr, goutweed, angelica, hogweed, parsley, cumin, coriander) corolla color, plant height (from 30 cm to 2 m) or umbrella diameter (from 8 to 30 cm). Among all the captured insects, the following groups can be distinguished: those found on P. sativa and on wild-growing species of Apiaceae - 6 species; on P. sativa and garden crops - 4 species; on P. sativa and Heracleum sosnowskyi - 4 species; found on many species of Apiaceae - 10 species; found only on P. sativa - 24 species.

Kinetic studies of catalytic and antioxidant activities of biosynthesized franklinite (ZnFe2O4) nanoparticles using Coriandrum sativum leaf extract

Abstract Industrialization and urbanization have now become major factors in damaging different segments of the environment. Synthesis of novel nanomaterials for the removal of dyes and free radicals from aqueous medium has become a challenge for the researchers. The present work describes formation of novel-franklinite (ZnFe2O4) nanoparticles (FNPs) which have been synthesized adopting economical route of green method using extracts of fresh and dried leaves of Coriandrum sativum. The fabricated NPs were characterized employing state of the art analytical techniques including UV-visible, FTIR, SEM and XRD. The nanocatalyst exhibited excellent catalytic properties for the degradation of eosin yellow up to 86 % in 22 min and 90 % in 16 min using zinc-ferrite NPs synthesized using dried and fresh leaves respectively. Antioxidant activity of ZnFe2O4 in terms of DPPH and ABTS free radicals scavenging was also determined. Nanoparticles synthesized using fresh leaves exhibited better antiradical potential in comparison to NPs synthesized dried leaves. Therefore, synthesis of FNPs with active features can be achieved using extract of fresh plant. Franklinite NPs can be used as promising photocatalyst for the degradation of organic pollutants and scavenging of free radicals.

LC-MS/MS and GC-MS Identification of Metabolites from the Selected Herbs and Spices, Their Antioxidant, Anti-Diabetic Potential, and Chemometric Analysis

Culinary herbs and spices are widely used in daily diets. Pakistan’s flora is enriched with phytochemicals due to a diverse range of land. Phytochemicals, including volatile and non-volatile compounds, have captured much interest due to their numerous health advantages and significance in daily diet. The present study aimed to conduct in-depth metabolomic profiling of Pakistani-grown fenugreek leaves (Trigonella foenum-graecum), fennel seeds (Foeniculum vulgare), mint leaves (Mentha royleana), coriander seeds (Coriandrum sativum) and basil leaves (Ocimum basilicum) by using liquid chromatography–mass spectrometry (LC-MS/MS) and gas chromatography–mass spectrometry (GC-MS). The first study was conducted to optimize extraction using different solvents (methanol, ethanol, chloroform, acetone, and water). Total phenolic content (TPC), total flavonoid content (TFC), and total condensed tannins (TCT) were quantified along with the antioxidant and anti-diabetic activities. The highest TPC (125.42 ± 10.89 mg GAE/g) and the highest antioxidant and anti-diabetic potential were quantified in mint. Seventy-one phytochemical metabolites were identified using LC-MS/MS, while forty-nine volatile constituents were identified using GC-MS. A positive correlation was identified between phenolic contents and their biological activities. Furthermore, molecular docking helped to find drug molecules with more excellent anti-diabetic activity based on their binding affinities. This study suggests that selected herbs and spices from Pakistan have significant nutraceutical and phytopharmaceutical potential. This study could further help in drug discovery.

Dietary coriander (Coriandrum sativum L) oil improves growth, nutrient utilization, antioxidant status, tissue histomorphology and reduces omega-3 fatty acid production in Nile tilapia (Oreochromis niloticus)

Coriander (Coriandrum sativum L.) is recently emerging as an antimicrobial growth promoter in aquafeed formulations. To assess the effect of coriander seed oil in the feed of Nile tilapia five iso-nitrogenous (crude protein 40%) and iso-lipidic (crude lipid 7%) diets were prepared with graded levels of coriander oil i. e., 0, 5, 10, 15 and 20 g/Kg referred as C0, C5, C10, C15 and C20, respectively. The fish were fed with the experimental diets twice daily for a period of 60 days in triplicate. After the feeding experiment, there observed a linear pattern in weight gain with the dietary coriander oil levels. The expression of hepatic insulin like growth factor 1 gene increased significantly in coriander oil supplemented groups in dose dependent manner in hepatic tissues of tilapia. The viscerosomatic and hepatosomatic index decreased significantly in the coriander oil treated groups. The crude protein contents increased significantly in the experimental groups; however, it did not vary significantly in between the groups. The crude lipid contents increased significantly in the last three groups (C10, C15 and C20) compared to C0 and C5. The serum glucose content decreased significantly in the last three groups i.e., C10, C15 and C20 coriander fed groups compared to C0. Whereas, the HDL level increased significantly in the 20 g/Kg treatment group compared to rest of the groups. Catalase activity increased significantly in the liver tissue of coriander oil treated groups compared to control. The liver histomorphology showed signs of storage of carbohydrate or lipid reserves in the form of vacuoles in the control group. However, in the coriander supplemented groups there was a reduction in hepatic vacuolar structures. The appearance of intestinal villi was enriched in coriander oil supplemented groups via branching. The Δ6/Δ5 desaturase increased significantly in the experimental groups compared to control. The Δ4 desaturase and elongase decreased significantly beyond 6.3% and 11.7% of coriander oil in the diet, respectively. There observed a significant increase in the percentage of saturated fatty acids in dose dependent manner. However, the unsaturated fatty acids including omega-3 fatty acids decreased significantly with an increase dose of coriander oil in feed of Nile tilapia. It can be concluded from the above study that coriander essential oil can be used for better growth performance, intestinal nutrient absorption, antioxidant activity and decreasing hyperglycemia in Nile tilapia. However, higher inclusion level (above 5 g/Kg) led to decrease in the wholebody omega-3 fatty acid production.

Management Soil Zones, Irrigation, and Fertigation Effects on Yield and Oil Content of Coriandrum sativum L. Using Precision Agriculture with Fuzzy k-Means Clustering

Precision agriculture (PA), management zone (MZ) strategies at the field level, soil analyses, deficit irrigation (DI), and fertilizer Variable Rate Application (VRA) are management strategies that help farmers improve crop production, fertilizer use efficiency, and irrigation water use efficiency (IWUE). In order to further investigate these management strategies, the effects of four soil MZ treatments, which were delineated using PA with fuzzy k-means clustering, two irrigation levels [IR1:FI = full drip irrigation (>90% of θfc), IR2:VDI = variable deficit drip irrigation (60–75% of θfc)], and four VRA fertilizations were studied on coriander yield and essential oil content in a two-year research project in Greece. A daily soil-water-crop-atmosphere (SWCA) balance model and a daily depletion model were developed using sensor measurements (climatic parameter sensors as well as soil moisture sensors). Unbalanced one-way ANOVA (p = 0.05) statistical analysis results revealed that correct delineation of MZs by PA with fuzzy k-means clustering, if applied under deficit irrigation and VRA fertilization, leads to increased essential oil content of coriander with statistically significant differences (SSD) and lower fruit yields; however, without SSD differences among management zones, when appropriate VRA fertilization is applied to leverage soil nutrient levels through the different fuzzy clustered MZs for farming sustainability. Moreover, VDI compared to full irrigation in different MZs yields 22.85% to 29.44% in water savings, thus raising IWUE (up to 64.112 kg m−3), nitrogen efficiency (up to 5.623), and N-P-K fertilizer productivity (up to 5.329).

Application of Coriander to Medical Cotton Bandage for the Development of Antimicrobial and Wound- Healing Properties

The aim of the research is to create a medical bandage utilizing an eco-friendly herb extract that is both antibacterial and wound-healing without the use of external dressing materials. The goal was accomplished by solvent extraction of the coriander herb (Coriandrum sativum). Ten layers of extracted solution were combined with one cotton bandage to create it using the pad-dry-cure technique. Following the same process, a second sample was created with a single layer using a ten-fold more concentrated coriander extraction solution. The K/S value measurement, SEM analysis, ATR analysis, and antimicrobial test were performed on treated materials. Implementations of the samples were made on a rabbit's wound site to demonstrate their ability to recover. The second sample's K/S value was remarkably similar to that of the first sample's tenth layer which was 0.89. The second sample's SEM picture showed that a significant amount of coriander extract had been deposited on the fibre surface. The presence of coriander extract's phytochemicals in the treated sample was confirmed by ATR analysis. Samples that had been padded with coriander extract had zones of inhibition (ZOI) against Grampositive and Gram-negative bacteria that were 14 mm and 12 mm, respectively, in terms of antibacterial activity. Healing of the wound showed good results when the bandages were removed after seven days. The wound had fully recovered. Environmentally friendly products are in high demand in the medical industry. Therefore, these modified samples are marketable for use as medical bandages.
