Phytochemical and Ethnopharmacological Review of Till Safeed (Sesamum indicum Linn.)

Within the management of health care, the traditional system of medicine remains indispensable. The Unani system of medicine treats a variety of illnesses with a range of medications derived from plants. Historically, people have utilized sesamum indicum seeds as a medicinal ingredient. Various parts of the plant have been used by traditional physicians. However, the dried seed and oil are commonly used as Till in Unani Medicine. The plant has a very long history of use as a medicinal herb. It can be used on its own or in compound pharmacopeial compositions with other medications. Till Safeed is an annual plant of family Pedaliaceae and this review article aims to describe morphological characteristics, phytochemistry, ethnobotanical uses and therapeutic properties of Till Safeed. So that subsequent study on any novel therapeutic activity based on phytochemistry can be conducted with greater simplicity and to support the revalidation of the drug's scientifically claimed actions as mentioned in classical literatures. We systematically searched classical Unani literature, online data sources (PubMed, Google scholar, Elsevier, Science Direct and Research Gate) and offline encyclopaedia and books on medicinal plants for the relevant data on Till Safeed. Polyunsaturated fatty acids, phytosterols, tocopherols, essential minerals, and a special class of phenylpropanoid chemicals called lignans—which include sesamin, sesamol, and sesamolin—are among the bioactive ingredients found in till seeds. The pharmacological characteristics of sesame lignans include. Antioxidant, antibacterial, antiproliferative, cholesterol-lowering, hepatic fatty acid oxidation enzyme-increasing, and anti-hypertensive properties. Keywords: Sesamum indicum, Unani Medicine, phytochemistry, sesamin, sesamolin.

Enhancing Functional Compounds in Sesame Oil through Acid-Soaking and Microwave-Heating of Sesame Seeds.

This study investigated whether pre-treating sesame (Sesamum indicum L.) seeds with a combination of acid-soaking and microwave-heating could significantly enhance the quality of the resulting sesame oil, particularly by increasing its content of functional compounds such as lignans, tocopherol, phytosterol, and squalene. The study revealed that soaking the sesame seeds in a solution of HCl and citric acid, along with microwave-heating, significantly increased the content of these compounds. The detected ranges were sesamin (1365-6927 µg g-1), sesamolin (605-3493 µg g-1), tocopherol (69.31-282.76 µg g-1), asarinin (ND-383.52 µg g-1), sesamol (ND-49.59 µg g-1), phytosterol (3690-6201 µg g-1), and squalene (532-1628 µg g-1). Additionally, the study found that the pre-treatment of sesame seeds had a minimal effect on the fatty acid composition, antioxidant activity (92.94-95.08% DPPH scavenging activity), and oxidative stability (2.13-2.90 mg MDA kg-1 oil). This is the first study to demonstrate that using acid-soaking and microwave-heating to prepare sesame seeds can produce sesame oil enriched with functional compounds, potentially benefiting cosmetic, pharmaceutical, and health applications.

Evaluation of Five Sesame (Sesamum Indicum L.) Varieties Under Varying Fertilizer Rates and Establishment Methods for Growth and Yield in Anyigba, Kogi State, Nigeria

Global sesame seed market is projected to have USD 7.24 billion in consumption value by 2024. However, its supply has not been able to match the demand due to several constraints to its production. This study was conducted at the Prince Abubakar Audu University Research and Demonstration Farm, during the 2023 cropping season to evaluate five sesame varieties for growth and yield under varying fertilizer rates and establishment methods. Treatment consisted of five sesame varieties, two establishment methods, and three fertilizer levels respectively combined factorially to obtain a total of thirty factorial treatment combinations and laid out in a Randomized Complete Block Design (RCBD) with three replicates. Results showed that varieties differed significantly (P < 0.05) in growth, yield and yield characters. YANDEV55 produced the widest leaf area at 9WAS, NCRIBEN-02M produced the highest number of leaves per plant (36) at 12WAS. The same variety (NCRIBEN-02M) consistently produced the tallest stems (42.48, 56.10, 80.48 & 93.46 cm) at 3, 6, 9 & 12WAS. YANDEV55 produced 73.6 % germination which was highest amongst others. E8 produced the highest number of capsule/plant (23.3) and number of seeds/plant (1428.94). NCRIBEN-05E performed optimally in yield characters such as total plant biomass yield (2908.0g/plot) and final seed yield (887.9kgha-1). NCRIBEN-02M had the highest haulm yield (33.0g/plot) while NCRIBEN-01M had the longest days (54.16) to 50% anthesis. Seed/capsule and Harvest index were not significantly affected by varieties. Broadcast method produced significantly widest leaf areas of 53.9 and 40.5 cm2 at 6 and 12 WAS respectively, higher number of leaves (18.0) at 3WAS. Drilling method of crop establishment produced the highest biomass yield (2894.6g/plot) and final seed yield (879.2 kgha-1). Similarly, fertilizer rates affect growth and yield characters; 100 kg NPKha-1 produced the widest leaf area, tallest plants and highest number of leaves/plant at all stages of sampling. These were at par with values obtained when plots were treated with 150kg NPKha-1. Alternatively, highest number of capsules/plant (22.4), seeds/capsule (62.46), seeds/plant (1502.73), total plant biomass yield (2879.7g/plot), haulm yield (33.0g/plot), final seed yield (870.7kgha-1) and longest number of days to 50% anthesis (53.6) were all obtained when plots were treated with 150 kgha-1 but was at par with 100kg NPKha-1. Fertilizer rates did not affect the establishment count and harvest index. The best variety with respect to yield/ha is NCRIBEN-02M, Application of 100 kg NPK/ha appears maximum for optimum yield of the crop, drilling appears to produce higher yield than broadcast for some varieties with an overall marginal increase of 8.4 % over broadcast and thus recommended for Anyigba environment. An economic study of the cost implication for both operations (drilling and broadcast) could be embarked upon to ascertain the veracity of this assertion, more so that broadcast requires higher seed rate than drilling. Significant interaction of varieties x establishment method was also an indication that very high yielding varieties (NCRIBEN-02M and NCRIBEN-01M) do better when drilled compared to broadcast. Significant positive relationship between some growth, yield and yield characters is an indication that effective crop improvement through selection can be carried out by selecting for those characters that correlated positively with yield.

Bioinformatics has emerged as a valuable tool for screening drugs and understanding their effects. This systematic review aimed to evaluate whether in silico studies using anti-obesity peptides targeting therapeutic pathways for obesity, when subsequently evaluated in vitro and in vivo, demonstrated effects consistent with those predicted in the computational analysis. The review was framed by the question: "What peptides or proteins have been used to treat obesity in in silico studies?" and structured according to the acronym PECo. The systematic review protocol was developed and registered in PROSPERO (CRD42022355540) in accordance with the PRISMA-P, and all stages of the review adhered to these guidelines. Studies were sourced from the following databases: PubMed, ScienceDirect, Scopus, Web of Science, Virtual Heath Library, and EMBASE. The search strategies resulted in 1015 articles, of which, based on the exclusion and inclusion criteria, 7 were included in this systematic review. The anti-obesity peptides identified originated from various sources including bovine alpha-lactalbumin from cocoa seed (Theobroma cacao L.), chia seed (Salvia hispanica L.), rice bran (Oryza sativa), sesame (Sesamum indicum L.), sea buckthorn seed flour (Hippophae rhamnoides), and adzuki beans (Vigna angularis). All articles underwent in vitro and in vivo reassessment and used molecular docking methodology in their in silico studies. Among the studies included in the review, 46.15% were classified as having an "uncertain risk of bias" in six of the thirteen criteria evaluated. The primary target investigated was pancreatic lipase (n = 5), with all peptides targeting this enzyme demonstrating inhibition, a finding supported both in vitro and in vivo. Additionally, other peptides were identified as PPARγ and PPARα agonists (n = 2). Notably, all peptides exhibited different mechanisms of action in lipid metabolism and adipogenesis. The findings of this systematic review underscore the effectiveness of computational simulation as a screening tool, providing crucial insights and guiding in vitro and in vivo investigations for the discovery of novel anti-obesity peptides.

Evaluating the Impact of Haryana’s Edible Oil Plant Resources on Human Health

Oil is odorless compound of herbs and spices and has been used for centuries to flavor and preserve foods, medicines and perfumes. There are many aromatic plant species in the Lamiaceae and Apiaceae plant families. Edible oils are produced in Haryana and is used for its beneficial effects on human health. The most common crops include peanuts, mustard, sunflower seeds, sesame seeds, soyabeans, wheat (rice bran), sunfflower, cotton, flaxseeds, etc. Takes place. Essential oils have many health benefits. The oil contains antioxidants. Vitamin E, plant sterols and polyunsaturated fatty acids (PUFA), which can lower cholestrol and prevent chronic diseases such as heart disease, diabetes and cancer. Fatty oils are divided into three types: drying and semi-drying oil, non-drying oil, and vegetable oil. The refined grades of drying and semi-drying oils are used to make edible oils, while the poorer grades are used to make soaps, varnishes, paints, candles, and other similar products. Oils contain a variety of bioactive chemicals (e.g., terpenoids), which have most biological effects and qualities in addition to their scent and flavor. Antibacterial, antifungal, antioxidant, insecticide, anthelminthic, acaricidal, larvicidal, anthelmintic, anti-inflammatory, cytotoxic, antibacterial, antiseptic, and local anaesthetic are just few of them.Oil compounds, such as geraniol, have recently demonstrated potential anticancer actions in cancer cells, triggering growth inhibition and death.

Synthesis of Linoleic Acid of Conjugated Isomers from Sesame (Sesamum Indicum) Seed Oil: Its Use and Effect in a Microstructured Product Type Oil-in-Water Emulsion

The development of functional foods is an area of great interest and innovation in the food industry. The use of conjugated linoleic acid (CLA) in food formulations has been growing in recent years due to its multiple health benefits. In this study, conjugated linoleic acid was obtained from sesame oil, and its use in the formulation of oil-in-water food emulsions was evaluated. Conjugated linoleic acid (CLA) was synthesized from the linoleic acid present in sesame oil using the alkaline isomerization method using proplyeneglycol as a solvent. The effect of alkali concentration (NaOH) and reaction time on the conversion of linoleic acid to CLA was evaluated. A 96.6% conversion of CLA was obtained with a NaOH concentration of 7% and a reaction time of 2 h. Emulsions were prepared using CLA as oil phase and soy lecithin, tween 80, carboxymethylcellulose as emulsifying agents. Emulsions with mixtures of carboxymethylcellulose and tween 80 were stable, presenting a non-Newtonian fluid behavior of pseudoplastic type (n<1). The Ostwald-de-Waele model shows an optimal fit to the experimental data of apparent viscosity (R2>0.99 ), and its microstructural characterization shows a homogeneous particle distribution. These results show that the alkaline isomerization process using propylene glycol as a solvent is an excellent alternative for the synthesis of CLA from vegetable oils such as sesame oil and its application in the development of microstructured products such as functional emulsions, and their subsequent application in the development of new food products with beneficial health characteristics.

Cracker is a palatable, crunchy snack that is most popular in India. Cracker is usually made with refined flour and sugar. This study aimed to develop and evaluate a millet-based cracker , using beetroot extraction finger millet flour, jowar flour, jaggery, sesame seeds(brown and black) and rice flour. As millets are considered nutritionally rich foods so they can be used to develop healthy and functional foods. Different levels of finger millet flour, jowar flour, and other ingredients were added in the proportions of 50%JF + 30%beetroot extraction + 10%OI (Sample A), 50%RFF + 30% beetroot extraction + 20%OI (Sample B), and 25%JF + 25%RF + 30% beetroot extraction+20%OI (Sample C) for the development of murukku and its sensory attributes were analyzed. The one-way ANOVA revealed a significant difference between the mean scores of at least two samples (F (2, 15) =3.7855, p=0.046, p<0.05[α]). Sample A (50JF + 30% beetroot extraction+ 20%OI) demonstrated desirable organoleptic properties based on taste panel studies. The selected sample A had an energy content of 699Kcal/100g, with 80.37g carbohydrates, 0.17g fat, 9.56g protein, 2.8g dietary fiber, calcium 45mg, and iron 5.5mg per 100g. While the total viable count and coliform count increased during a month storage period from 1 to 2 and 1 to 1.7 respectively, harmful bacteria such as E. coli, salmonella, and staphylococcus were absent in initial and final assessments. The pH increased from 7.1 to 7.6 during storage. The color, odor, and taste of the sample scored 4.5 initially but decreased to 3.0 at the end, while the texture remained constant with a score of 3.0 throughout storage

Evaluation of Quality Attributes and Rheological Behavior of Tahini with Addition of Natural Sweetener and Cocoa Liquor

Tahini is a globally recognized creamy paste made from sesame seeds, whose seeds are widely produced in Colombia but little used in the production of products. Therefore, the objective of this study was to evaluate the quality attributes through proximal, microbiological, and sensory analysis, and the rheological behavior of tahini with the addition of natural sweetener, honey, and cocoa liquor as sensory additives, using local crops. A 2X2X2 factorial design with sesame paste, honey concentration, and cocoa liquor as factors were used to prepare tahini. Proximal, microbiological, and sensory analyses were carried out to determine the bromatology, microbiological suitability, and sensory acceptability, respectively. The rheological behavior was studied by shear rate sweep, controlling the deformation 1x10-² s-1 to 1x10-² s-1 with a fit to the Ostwald de Waele model. The rheological characterization of the formulations showed that all of them exhibited pseudoplastic flow behavior, with F4 standing out as having a higher apparent viscosity. Finally, formulation F4 showed the best bromatological, rheological, and sensory characteristics, demonstrating that the incorporation of new ingredients can modify traditional tahini to promote its consumption.

The Effect of Apis mellifera L. Pollination on Seed Yield and Nutritional Qualities of Sesamum indicum L. in Dale Sedi District of Western Oromia, Ethiopia

ABSTRACTThe development of blossoming seed plants that provide a genetically diverse crop of progeny depends on pollination. Sesamum indicum is an oilseed crop and requires both self and cross‐pollination that varies based on insect type, crop variety, and environmental factors. Hence, the experiment was conducted for two consecutive years (2022 and 2023) to the effect of Apis mellifera L. pollination on yield, germination, and nutritional qualities of S. indicum (Dicho variety). A completely randomized block design with three treatments was used, and each treatment was replicated four times. Insects from open plot were counted from 1 m × 1 m quadrant/5 min. Seed yield and yield parameters and germination rates were recorded based on standard methods. Oil content was analyzed by Soxhlet extraction. From the study, 13 insects were identified of which 69.2% were categorized under the order Hymenoptera. A combined mean of plant height, branch/plant, and number of pod/plant showed statistically no difference (p > 0.05) among treatments. However, the number of seeds/pod, 1000 seed weight, and yield (quintal)/ha produced by an open plot and a plot caged with A. mellifera were statistically higher (p < 0.05) as compared with the closed plot. The percentage increment in seed yield (quintal)/ha were 17.16% and 20.33% for the open plot and the plot caged with bees, respectively. The seed germination was found to be maximum in the open plot (88.9%) followed by a plot caged with A. mellifera (86.68%) and a closed plot (60.46%). A measurable variation (p < 0.05) in oil content(%) was recorded among the treatments with the maximum from a plot caged with bees (54.24 ± 0.27) followed by an open plot (52.04 ± 0.58) and closed plot (48.81 ± 0.24). These findings suggest that pollinators, including honey bees, A. mellifera visiting S. indicum can enhance yields, germination rates, and oil content.

Chemometric Modeling Revealed Oleic and Linoleic Acids as Varietal Biomarkers for Six Sesame Varieties-In Vitro and UHPLC Analyses.

Pakistan once considered self-sufficient for edible oil production now became the major importer with 88.6% imports and producing only the minor portion. Scientific negligence in oil seed crops led to a dramatic decrease in edible oil production depending mainly on only the imports. Sesamum indicum L., "Queen of Oil seeds" with 50-55% oil, is cultivated in various geographical regions of Pakistan, but farmers are not considering this crop because of insufficient knowledge, poor crop management practices, and low yielding varieties. This study was conducted to check the nutritional, biochemical, antioxidant, and yield potentials of six major varieties, i.e., TS-5, TH-6, Til-18, NIAB-Mil, NIAB-Pearl, and NS-16, and to compare the nutritionals, oil quality, and oil yield potential of these varieties. Field experiment was conducted, and various crop growth biomarkers were analyzed. Chlorophyll content and superoxide dismutase activity were found to be highest in NIAB-Mil followed by NIAB-Pearl and comparable to those of Til-18, while APX, Cat, and GPX activity was found to be highest in Til-18 with 25.6 and 5.9 and 6.02 mg/g, respectively. Seed antioxidant parameters showed a mixed response, but NIAB-Mil, NIAB pearl, and Til-18 were found to be highest in all antioxidant parameters. UHPLC analysis of seed oil resulted in a total of 14 triacylglycerols (TAGs), and principal component analysis and OPLS-Da analysis showed seven TAG biomarkers responsible for the separation of sesame varieties. Til-18 was found to be highest in oil content (53.3%) more abundant with oleic acid, while NIAB-Pearl, NIAB-Mil, and NS-16 were found to be abundant with linoleic acid, both considered as potential TAG biomarkers for sesame oil separation. This study concluded that, in general, Til-18 variety is more resistant with high nutritional status, high antioxidant activity, and oil yielding variety, followed by NIAB-Mil and NIAB-Pearl.

Overexpression of a 'Paulownia fortunei' MYB Factor Gene, PfMYB44, Increases Salt and Drought Tolerance in Arabidopsis thaliana.

Paulownia fortunei (Seem.) Hemsl is a Paulownia Sieb.et tree of the family Scrophulariaceae. It has become an important short-to-medium-term fast-growing multi-purpose tree species in China due to its rapid growth, strong adaptability, and excellent material properties. MYB transcription factors in plants have numerous and diverse functions, playing important roles in various aspects such as plant stress response. To investigate the function of MYB transcription factors in Paulownia fortunei, this study used PCR technology to clone the PfMYB44 gene from Paulownia fortunei. The homology of PfMYB44 and SiMYB44 (Sesamum indicum) was the highest. Expression analysis results showed that PfMYB44 was expressed in the root, stem, young leaf, and mature leaf of Paulownia fortunei, with the highest content in the root. Cold, drought, hot, salt, and ABA treatments could increase the expression level of PfMYB44. Overexpression-PfMYB44 plants were constructed, and physiological and molecular analysis showed that PfMYB44 could positively regulate salt and drought stresses. Under drought stress, the expression levels of AtP5CS, AtCAT1, AtNCED3 and AtSnRK2.4 in transgenic lines were significantly induced. Salt stress induced the expression of AtNHX1, AtSOS1, AtSOS2 and AtSOS3 genes, and the relative expression levels of these genes in transgenic Arabidopsis were higher. In conclusion, the functional study of PfMYB44 laid a certain foundation for the study of Paulownia stress resistance, and was helpful to the study of its stress resistance mechanism and the cultivation of new stress resistance varieties.

Novel antimicrobial polysaccharide hydrogel with fertilizer slow-release function for promoting Sesamum indicum L. seeds germination

The problem of seed germination is one of the important scientific and technological issues facing the field of agroforestry cultivation, and the germination process requires both sufficient water and certain nutrients. The high solubility of fertilizers and pesticides makes their utilization inefficient, while water resources are costly in difficult standing environments. This article innovatively provides the preparation of hydrogels with slow-release function by using cellulose and chitosan as substrates, which have high water retention capacity and long-lasting fertilizer release (CCH/PVA/NCC/NPK). In this study, cellulose chitosan hydrogel (CCH) with 50 wt% of chitosan, 1 wt% of polyvinyl alcohol solution (PVA), 0.5 wt% of nanocellulose solution (NCC), and 2.5 wt% of nitrogen, phosphorus, and potassium (NPK) solution were used in optimized conditions to successfully prepare hydrogel materials with swelling as high as 79 g g−1 of CCH/PVA/NCC/NPK. Under neutral conditions, CCH/PVA/NCC/NPK has the slowest water release rate and the strongest water retention capacity, and it can greatly reduce the amount of fertilizers and the consumption of water resources, and it has a wide range of applications and prospects for development.

Using rice bran as a press aid during the cold‐pressing of sesame seeds improved the extraction yield and quality of the resultant oil

AbstractSimple, cost‐effective, and practical techniques can enhance the shelf life of cold‐pressed oils. This study evaluated sesame seed (SS) cold‐pressed oil with various percentages of rice bran (RB) as press aid, including 0% (control or TSSO), 1% (T1), 2.5% (T2.5), 5% (T5), 7.5% (T7.5), and 10% (T10) w/w. The results demonstrated that adding RB considerably boosted extraction yields (p < .05), with 5% RB constituting the ideal combination. Adding 7.5% and 10% RB to the SS reduced free fatty acid (FFA) levels compared to the control sample. The oxidative stability index (OSI) and peroxide value (PV), however, significantly increased at combination ratios ranging from 2.5% to 10% (p < .05). Rice bran oil (TRBO) had the greatest OSI of all the studied oils, with 18.99 h, while the extracted oils showed an increase in OSI as RB contents rose. Total phenolic compounds (TPC), tocopherols, γ‐oryzanol content, and total antioxidant activity (TAA) increased directly with the RB level. Despite the addition of RB altering the fatty acids concentration, linoleic and oleic acids continued to be the predominant fatty acids in TSSO, TRBO, and other extracted oil samples. Increasing the combination ratio increased the palmitic, palmitoleic, oleic, and linolenic acid content and decreased the stearic and linoleic acid content. In summary, the study demonstrated that the simultaneous cold‐pressing of oil‐bearing seeds and agro‐industrial by‐products is a potentially advantageous technique to increase the extraction yield, qualitative attributes, and shelf life of the extracted oils without the addition of synthetic antioxidants.
