The effect of administering aqueous extract of fermented Moringa oleifera leaves via drinking water on performance and carcass characteristics of broilers

The need to adopt natural herbal plants as feed additives in poultry production has received attention among poultry nutrition and production experts in recent years. Herbal plants have few or no side effects, unlike synthetic additives. The aim of the research was to examine the effect of fermented Moringa oleifera leaf aqueous extract (FMLAE) on growth performance and broiler carcass characteristics. A total of 240 healthy day-old-chick broilers with homogeneous average body weight were randomly divided into 4 treatments and 6 replications with 10 heads per cage in a completely randomized design. Fermented Moringa leaf aqueous extract (FMLAE) treatment was given through drinking water at levels: 0% as control (A); 2% (B), 4% (C), and 6% (D), respectively. The results showed that FMLAE supplementation in drinking water had a significant increase (P<0.05) in body weight gain, carcass weight, carcass percentage, feed consumption and feed efficiency. It can be concluded that the addition of 2-6% fermented Moringa leaf aqueous extract (FMLAE) to the drinking water of broilers aged 0-4 weeks significantly increases growth, carcass and feed efficiency.

Microalgae separation in MP-PVC contaminated wastewater using plant-based coagulant over different extraction methods in Bauru, Brazil

This study investigates the effectiveness of coagulation-flocculation and sedimentation (CFS) for separating microalgae, focusing on the use of various Moringa oleifera extracts as natural coagulants. We examined photobioreactor effluent (PBR) both with and without microplastic PVC (MP-PVC) contamination, referred to as PBR R2 and PBR R1, respectively. Utilising response surface methodology, we identified optimal conditions for the removal of microalgae and MP-PVC. Validation tests demonstrated that the aqueous extract of delipidated Moringa oleifera powder (AEDMOP) achieved high removal efficiencies, with coagulant dosages of 630 mg L−1 for PBR R1 and 625 mg L−1 for PBR R2. Both conditions showed microalgae removal efficiencies exceeding 83% for turbidity, colour, OD540 nm, OD680 nm, and OD750 nm, and 63% for OD254 nm. Interestingly, the optimised conditions for PBR R2 required slightly less coagulant, likely due to the additional particulate matter from MP-PVC. While extracellular polymeric substances (EPS) exhibited a marginal effect on flocculation, further investigation into their role in CFS is necessary. Our findings highlight the potential of AEDMOP for efficient microalgae separation, even in the presence of microplastics.

Microstructures, optical, magnetic properties, and specific absorption rate of novel magnetite/mesoporous silica nanoparticles synthesized using green route for magnetic hyperthermia application

In this study, novel magnetite (Fe3O4)/mesoporous silica nanoparticles (MSN) were prepared by the green synthesis method using Moringa oleifera extract with various MSN concentrations. The crystallite size of Fe3O4/MSN decreased from 10.5 to 9.0 nm with the increase of MSN concentrations. However, as shown from transmission electron microscope images, the surface modification process increases its particle size from 10.7 ± 0.1–27.8 ± 0.3 nm. Scanning electron microscopy images revealed that MSN has a porous structure, and the shape of Fe3O4/MSN was nearly spherical. The Fourier transform infrared spectra showed the functional group of Si-O-Si at 1041 cm−1, indicating a successful surface modification process. After modification using MSN, the band gap energy of the nanoparticles decreased from 3.61 to 3.27 eV. The magnetic properties analysis showed that the saturation magnetization of Fe3O4 and Fe3O4/MSN was 55.32 ± 0.03 emu/g and 53.45 ± 0.04 emu/g, respectively. In contrast, the coercivity increased from 57.7 ± 0.3–149.5 ± 0.5 Oe. Additionally, the specific absorption rate (SAR) of Fe3O4/MSN to evaluate its potential for magnetic hyperthermia applications were investigated. The highest SAR values of Fe3O4 and Fe3O4/MSN were 91.8 mW/g and 86.7 mW/g, which decreased with increasing MSN concentrations. Furthermore, these results proved that the green-synthesized Fe3O4/MSN was a promising candidate and potentially optimized the performance of future magnetic hyperthermia applications.

Moringa Oleifera leaf-based zinc oxide nanoparticles: Green synthesis, characterization, and their antibacterial investigations

In the current study, an extract from Moringa Oleifera (MO) leaves was utilized for synthesis nanoparticles (ZnO) in an easy-to-use and ecologically friendly manner. Different ratios of MO leaf extraction (1:1, 1:3, 1:5, and 1:7, 1:9) were used to synthesize the nanostructured ZnO. The synthesized ZnO NPs were examined using an array of analytical methods, including energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV–Vis absorption spectroscopy, and antibacterial investigations. The synthesized MOL: ZnO NPs confirmed the hexagonal wurtzite structure, as demonstrated by XRD analysis. FT-IR demonstrated that the presence of distinct functional groups was required for the reduction of the metal ion into MOL: ZnO NPs. High purity and crystalline EDX has been used to identify the intense and narrow measurements of the zinc and oxygen found in the MOL: ZnO NPs. After being examined for antibacterial activity, the produced MOL: ZnO NPs showed the highest zones of inhibition against both gram negative Pseudomonas and gram positive Bacillus. The results show that ZnO-based NPs aided by leaf extract of Moringa Oleifera are the promising materials for a variety of applications such as food package applications and advanced forensic applications.

In-vitro Antifungal Activity of Ethanol Plant Extracts of Moringa oleifera, Vernonia amygdalina and Ocimum gratissimum against Some Clinical Candida Species

Potential Use and Chemical Analysis of Some Natural Plant Extracts for Controlling Listeria spp. Growth In Vitro and in Food.

Listeria are Gram-negative intracellular foodborne pathogens that can cause invasive infections with high mortality rates. In this work, the antibacterial activity of ten essential oils, infusion extracts, and decoction extracts of some medicinal plants was tested against Listeria monocytogenes and listeria ivanovii strains. The effects of different physical conditions including temperature, pH, sodium chloride, and some organic acids were studied. The results showed that the water extracts gave the maximum bacterial inhibition, while ethanolic extract was inactive against the tested Listeria spp. The antibiotic sensitivity of L. monocytogenes LMG10470 and L. ivanovii LMZ11352 was tested against five antibiotics including imipenem, levofloxacin, amikacin, ampicillin, and amoxicillin. Imipenem was the most effective antibiotic, resulting in inhibition zones of 40 mm and 31 mm for L. monocytogenes and L. ivanovii, respectively. When imipenem mixed with Syzygium aromaticum oil, Salvia officinalis oil, Pimpinella anisum infusion, and Mentha piperita infusion each, the water extract of Moringa oleifera leaves and seeds against LMG10470 and LMZ11352 resulted in broader antibacterial activity. The antimicrobial activity of both Pimpinella anisum and Mentha piperita plant extracts is related to a variety of bioactive compounds indicated by gas chromatography-mass spectrometry analysis of these two plant extracts. These two plant extracts seemed to contain many chemical compounds elucidated by gas chromatography-mass spectrometry (GC-MS) and infrared radiation spectra. These compounds could be classified into different chemical groups such as ethers, heterocyclic compounds, aromatic aldehydes, condensed heterocyclic compounds, ketones, alicyclic compounds, aromatics, esters, herbicides, saturated fatty acids, and unsaturated fatty acids. The use of these natural compounds seems to be a useful technological adjuvant for the control of Listeria spp. in foods.

The Effects of Moringa Leaf Extract on the Growth and Microbial Load of Boiler

The adverse effect of microbes in poultry production, especially broiler chicken remains a major concern for poultry breeders. This study determined the effects of Moringa leaf (Moringa Oleifera) extract on the performance and microbial loads of broiler birds. A total of 25 broiler chicks were used and separated into 5 groups in an iron pen with 5 chicks in each group. Group 1 (control, with no treatment), group 2 (received a treatment of 62.5mg/L), group 3 (received a treatment of 125mg/L), group 4 (received a treatment of 250mg/L), group 5 (received a treatment of 500mg/L). After 4 weeks of treatment, the faeces from each group, the control group inclusive were collected for microbial analysis. The result showed that the Moringa Oleifera leaf extract at all doses recorded non-significant difference in the parameters analysed among the groups. It was also noticed that the disparities of the results were great. Some as much as 11.5 and 168. 37 standard error of mean. Moreover, Group 3, receiving 125mg/L, exhibited a substantial reduction in E. coli, salmonella, total bacteria count, and pseudomonas activities compared to other groups. Group 3 had the highest water consumption. Amongst the treatment group, group 3 had the highest increase in weight. In conclusion, Moringa leaf extract effectively lowered the microbial load in broiler chicks at the treatment of 125mg/L without any adverse effects. Keywords: Moringa Oleifera, Moringa leaf, microbial load, broiler birds.

Phytochemical screening, antimicrobial, antioxidant, anticancer activities on cervical cancer cell lines and aero-digestive extract of Moringa oleifera

The phytochemical screening showed that the Moringa oleifera (MO) extract contained many compounds such as polyphenols, polyterpenes, sterols, reducing sugars, and hydrolysates tannins. The MICs of MO extract for microbial strains is 0.73 mg/ml for Escherichia coli, Pseudomonas aeruginosa, 7.5 mg/ml for Enterococcus faecalis, Staphylococcus aureus and 0.5 mg/ml for Candida albicans. The MO extract has an IC50 of 3.403 mg/ml has an antioxidant activity by DPPH radical scavenging. The cytotoxic activity of MO extract was evaluated by determining the content of lactate dehydrogenase released by the lysed cells. MO extract exhibited cytotoxic activity against HeLa and FaDu cell lines with an identical IC50 value of 25 µg/ml. We did not observe any remarkable decrease cytotoxic activity when these lines were exposed to the MO extract after 48 h. Our findings help to support the promising role of MO as anticancer agent and open a new challenge for studying DNA fragmentation.

Nutritional Changes in stored Tomatoes (Solanum lycopersicum L.) as influenced by Silver Nanoparticles Coating

This study evaluated the influence of silver nanoparticle (AgNP) coating on the nutritional content of stored tomato fruits. Silver nanoparticles was fabricated via the green method of synthesis using ethanolic extract of Moringa oleifera leaves as reducing, capping and stabilizing agent. The antimicrobial efficacy was evaluated at various concentrations (10 – 100 ppm) against Aspergillus niger, Aspergillus paraciticus, Aspergillus flavus and Fusarium oxysporum. Silver nanoparticle coating was prepared from a mixture of silver nanoparticles, carboxyl methyl cellulose (CMC) and sodium caseinate with glycerol as plasticizer.

Rutin of Moringa oleifera as a potential inhibitor to Agaricus bisporus tyrosinase as revealed from the molecular dynamics of inhibition

Tyrosinase is a binuclear copper-containing enzyme that catalyzes the conversation of monophenols to diphenols via o-hydroxylation and then the oxidation of o-diphenols to o-quinones which is profoundly linked to eukaryotic melanin synthesis and fruits browning. The hyperpigmentation due to unusual tyrosinase activity has gained growing health concern. Plants and their metabolites are considered promising and effective sources for potent antityrosinase enzymes. Hence, searching for potent, specific tyrosinase inhibitor from different plant extracts is an alternative approach in regulating overproduction of tyrosinase. Among the tested extracts, the hydro-alcoholic extract of Moringa oleifera L. leaves displayed the potent anti-tyrosinase activity (IC50 = 98.93 µg/ml) in a dose-dependent manner using L-DOPA as substrate; however, the kojic acid showed IC50 of 88.92 µg/ml. The tyrosinase-diphenolase (TYR-Di) kinetic analysis revealed mixed inhibition type for the Ocimum basilicum L. and Artemisia annua L. extracts, while the Coriandrum sativum L. extract displayed a non-competitive type of inhibition. Interestingly, the extract of Moringa oleifera L. leaves exhibited a competitive inhibition, low inhibition constant of free enzyme (Kiiapp\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$${\ ext{K}}_{\ ext{ii}}^{\ ext{app}}$$\\end{document}) value and no Pan-Assay Interfering Substances, hinting the presence of strong potent inhibitors. The major putative antityrosinase compound in the extract was resolved, and chemically identified as rutin based on various spectroscopic analyses using UV–Vis, FTIR, mass spectrometry, and 1H NMR. The in silico computational molecular docking has been performed using rutin and A. bisporus tyrosinase (PDB code: 2Y9X). The binding energy of the predicted interaction between tropolone native ligand, kojic acid, and rutin against 2Y9X was respectively − 5.28, − 4.69, and − 7.75 kcal/mol. The docking simulation results revealed the reliable binding of rutin to the amino acid residues (ASN260, HIS259, SER282) in the tyrosinase catalytic site. Based on the developed results, rutin extracted from M. oleifera L. leaves has the capability to be powerful anti-pigment agent with a potential application in cosmeceutical area. In vivo studies are required to unravel the safety and efficiency of rutin as antityrosinase compound.

In Vitro Antioxidant, Anti-Inflammatory Activity and Bioaccessibility of Ethanolic Extracts from Mexican Moringa oleifera Leaf.

This study aimed to assess the antioxidant and anti-inflammatory properties, and bioaccessibility of Moringa oleifera ethanolic extracts using pressurized liquid extraction with varying ethanol concentrations (0%, 30%, 50%, 70%, and 100%) in water-ethanol mixtures. Quercetin derivatives and neochlorogenic acid were identified as major compounds via high-performance liquid chromatography with diode array detection. The 70% ethanol extract displayed the highest antioxidant activity and phenolic content, highlighting a strong correlation between phenolics and antioxidant potential. Extracts prepared with 50% and 70% ethanol (30 μg/mL) significantly inhibited TNF-α, IL-1β, and IL-6 cytokine secretion, with the 70% ethanol extract demonstrating robust anti-inflammatory effects. During in vitro digestion (oral, gastric, and intestinal phases), minimal changes were noted in most phenolic compounds' post-oral phase, but reductions occurred after the gastric phase. Substantial decreases in major compounds and antioxidant activity were observed in post-gastric and intestinal phases. Overall, ethanolic extracts of Moringa oleifera, particularly those with 70% ethanol, exhibit promising antioxidant and anti-inflammatory properties, suggesting potential for developing therapeutic agents against oxidative stress and inflammation-related disorders. However, it is essential to protect these compounds to prevent their degradation during digestion.

Facile green synthesis of plant-mediated selenium nanoparticles (SeNPs) using Moringa oleifera leaf and bark extract for targeting α-amylase and α-glucosidase enzymes in diabetes management

In recent years, nanoparticle synthesis innovations have focused on developing simple, cost-effective, non-toxic, and eco-friendly methods. This study investigates the green synthesis of selenium nanoparticles (SeNPs) using aqueous extracts of Moringa oleifera leaves (ML) and bark (MB) via the precipitation method. The synthesized SeNPs were characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). TEM analysis revealed the formation of approximately spherical particles with average sizes ranging from 10.47 nm to 28.5 nm for SeNPs synthesized with ML (SeNPsML) and 15.47 nm–32.83 nm for those with MB (SeNPsMB). XRD analysis indicated that SeNPsMB were predominantly crystalline, while SeNPsML were mainly amorphous with a few crystalline peaks. Morphological studies showed spherically shaped particles with a high degree of agglomeration, evenly distributed throughout the matrix. SeNPsMB exhibited higher dose-dependent inhibition of α-amylase and α-glucosidase compared to SeNPsML, likely due to differences in nanoparticle size and form. These findings suggest that SeNPsMB may possess superior antidiabetic activity.

Biosynthesis of iron oxide nanoparticles using plant extracts and evaluation of their antibacterial activity

The biosynthesis of iron oxide nanoparticles has received increasing attention in the field of food nanotechnology because of their non-toxicity, high efficiency, high antibacterial power, and decontamination features. Therefore, biosynthesis of iron oxide nanoparticles (nFe) was prepared from the leaves of some vegetables, such as cabbage (C) and turnips (T), as well as moringa leaves (M). Alcoholic extracts of these nanoparticles were also tested on Staphylococcus aureus and Escherichia coli to evaluate their antibacterial activity. The results revealed that the particle sizes of the biosynthesis nanomaterials studied ranged from 12.99 to 22.72 nm, and the particles were spherical, irregular, and surrounded by black color. It also contains many functional groups and minerals. Iron nanoparticles modified with Moringa oleifera extract at a concentration of 200 ppm had the highest phenol content compared to other biosynthesis nanoparticles studied. TnFe and MnFe at 200 ppm had a maximum zone of inhibition of 25 mm and 24 mm against Staphylococcus aureus and Escherichia coli, respectively. While the minimum inhibition zone of 8.0 mm was observed at 25 ppm for nFe against Escherichia coli. Therefore, it is recommended to use these extracts of biosynthesis iron oxide nanoparticles as antibacterial agents for stored foods.

13-Week repeated-dose toxicity study of optimized aqueous extract of Moringa oleifera leaves in mice

Ethnopharmacological relevanceMoringa oleifera (Moringaceae family), commonly known as horseradish or tree of life, is traditionally used for various diseases, such as diabetes, hypercholesterolemia, neurological disorders, among others. Aim of the studyTo evaluate the toxicological profile of the oral use of an aqueous extract of Moringa oleifera leaves for 13 weeks in mice. Materials and methodsInitially, a factorial design (23) was carried out to optimize aqueous extraction using as variables; the extraction method and proportion of drug. The 13-week repeated-dose toxicity trial used female and male mice, with oral administration of aqueous extract of Moringa oleifera leaves at doses of 250, 500, and 1000 mg/kg. The animals were evaluated for body weight, water and feed intake, biochemical and hematological parameters, urinalysis, ophthalmology and histopathology of the liver, spleen and kidneys. ResultsThe extraction efficiency was evidenced by the extraction by maceration at 5%, obtaining the optimized extract of Moringa oleifera (OEMo). The oral administration of OEMo did not promote significant difference (p > 0.05) in the weight gain, food and water consumption of the control animals and those treated with 250 and 500 mg/kg. However, treatment with 1000 mg/kg promoted a reduction (p < 0.05) in food intake and body weight from the 7th week onwards in male and female mice. No alterations were detected in the hematological and histological parameters in the concentrations tested for both sexes. The highest concentration treatment (1000 mg/kg) promoted an increase in transaminases in males and females. All concentrations promoted a significant decrease (p < 0.05) in the serum lipid profile of mice. ConclusionThis study developed an optimized extract of Moringa oleifera leaves, which should be used with caution in preparations above 500 mg/kg for the long term because it leads to significant changes in liver enzymes. On the other hand, the extract proved to be a promising plant preparation for hyperlipidemia in mice.

Green Synthesis of Silver Nanoparticles using Moringa oleifera: Implementation to Photoantimicrobial of Candida albicans with LED Light

Green synthesis of silver nanoparticles using Moringa oleifera (AgNPs/MO) was carried out to produce nanoscale antifungal agents which are used as photosensitizing agents in photoantimicrobial therapy. This study focused on investigating the potential of AgNPs/MO producing some toxic radical compounds that inhibit the growth of Candida albicans biofilms. The inhibition mechanism uses the principle of photoinactivation treatment which combines a photosensitizer with an LED light source at a power of 100 mW for 60 - 300 s of exposure. Quantitative data analyzed were the number of viable cells and radical compounds, formed by malondialdehyde (MDA) level. It is investigated through staining the XTT (2,3-Bis-(2-Methoxy-4-Nitro-5-Sulfophenyl)-2H-Tetrazolium-5-Carboxanilide) and TBARS (Thiobarbituric Acid Reactive Substances). The results show that the maximum wavelength of AgNPs is 440 nm while the Moringa oleifera has 2 peaks at 425 and 635 nm. The maximum effect occurred in the group of photosensitizer AgNPs/MO combined LED with percentage inactivation about 76.80 % for blue LEDs and 76.20 % for red LEDs. The group of LED irradiation without photosensitizer obtained about 51.85 % for blue LEDs and 50.04 % for red LEDs. The MDA level group of AgNPs/MO combined LED also produced MDA levels of 1.772 nmol/mL for blue LED and 1.617 nmol/mL for red LED. Meanwhile, the application of photoantimicrobial using only LEDs produced MDA levels of only 1.353 nmol/mL for blue LEDs and 1.347 nmol/mL for red LEDs. This research has shown that the green synthesis of AgNPs/MO has a good potential to inhibit the growth of Candida albicans biofilms as a photosensitizer agent. HIGHLIGHTS Silver nanoparticles (AgNPs) combined with Moringa oleifera (MO) extract have been shown to have potential as a photosensitizer to inhibit the growth of Candida albicans Green synthesis AgNPs/MO have a characteristic spectrum at 440 nm which is close to the blue light spectrum. Green synthesis AgNPs/MO combined with LED light irradiation energy can reduce the cell viability of Candida albicans up to 76.80 % through the XTT assay staining test method and produce 1.772 nmol/mL of Malondialdehyde that reacts with ROS compounds to cause cell damage. GRAPHICAL ABSTRACT

Newly synthesized chitosan nanoparticles loaded with caffeine/moringa leaf extracts Halt Her2, BRCA1, and BRCA2 expressions

Breast cancer is among the highest morbidity and mortality rates in women around the world. In the present investigation we aimed to synthesis novel nanosystem combining two naturally important anticancer agents with different mechanism of action namely Moringa oleifera and caffeine. Firstly, chemical analysis of Moringa oleifera extract and caffeine was done by gas chromatography-mass spectroscopy (GC–MS) in order to assess the main chemical compounds present and correlate between them and the possible anticancer effect. The novel nanosystem was characterized through dynamic light scattering techniques which revealed the stability and homogeneity of the prepared M. oleifera leaves extract/Caffeine loaded chitosan nanoparticles, while FTIR and transmission electron microscope (TEM) proved the shape and the successful incorporation of M. oleifera leaves extract/Caffeine onto the nanochitosan carrier. Our initial step was to assess the anticancer effect in vitro in cancer cell line MCF-7 which proved the significant enhanced effect of M. oleifera leaves extract/Caffeine nanosystem compared to M. oleifera leaves extract or caffeine loaded nanoparticles. Further studies were conducted in vivo namely tumor biomarkers, tumor volume, bioluminescence imaging, molecular and histopathological investigations. The present study proved the potent anticancer effect of the synthesized M. oleifera leaves extract/Caffeine loaded chitosan nanoparticles. Mo/Caf/CsNPs exhibited a large number of apoptotic cells within the tumor mass while the adipose tissue regeneration was higher compared to the positive control. The prepared nanoparticles downregulated the expression of Her2, BRCA1 and BRCA2 while mTOR expression was upregulated. The aforementioned data demonstrated the successful synergistic impact of Moringa and caffeine in decreasing the carcinoma grade.

Moringa oleifera and Tinospora cordifolia is extensively used as an ingredient of food and in traditional medicine for the management of a variety of diseases. The extracts of leaf of Moringa oleifera and stem of Tinospora cordifolia were assessed to examine their ability to inhibit the oxidative DNA damage (by DNA protection assay), cytoprotective and genoprotective potential (by Comet assay) in V79 cells individually and in combinations. It was found that these extracts could significantly inhibit the OH-dependent damage of pUC18 plasmid DNA. M. oleifera extract (160 and 320μg/mL) and Tinospora cordifolia extract (640, 1,280 and 2,560μg/mL) individually showed higher DNA protection activity. M. oleifera (1,280μg/mL) combined with Tinospora cordifolia (640μg/mL) showed best cytoprotective and genoprotective activities among different concentration combinations and various concentrations of individual plants in V79 cell line against hydrogen peroxide induced cytotoxicity and genotoxicity. This study demonstrates the cytoprotective and genoprotective activity of M. oleifera and Tinospora cordifolia individually or in combination.

Restraint of Starch-hydrolyzing Enzyme in the Management of Postprandial Blood Glucose Level: An Alternative Approach

Background: Diabetes is a multifaceted metabolic condition defined by postprandial hyperglycemia with perturbances in the majority of the metabolic systems in the human body. α-amylase is a key enzyme present in pancreatic juice and saliva that converts one of the common food sources i.e., starch molecules into absorbable molecules and raises plasma glucose levels. Reducing starch digestion by the inhibitors of starch hydrolyzing enzymes could be an intriguing strategy for improved postprandial hyperglycemia management. Objective: The present research work was undertaken to evaluate the inhibition potential of natural inhibitors of α-amylase from Trichosanthes dioica (pointed gourd) and Moringa oleifera (moringa leaves) extracts in vitro. Furthermore, in vivo cytotoxicity assessment was also conducted through brine shrimp lethality bioassay. Methods: Different organic solvents (namely acetone, ethanol, and methanol) were used to isolate plant extracts. DNS (3,5-dinitrosalicylic acid) was used to conduct the α-amylase inhibition assay. The safety of the natural inhibitors was determined by the most common technique i.e, brine shrimp lethality bioassay. Results: Among all the different organic solvent extracts, pointed gourd and its peel exhibited the highest α-amylase inhibition activity (64.03 ± 7.33–69.40 ± 9.38%) which is very close to standard α-amylase inhibitor acarbose (72.34 ± 4.23%) whereas moringa leaves showed moderate inhibition activities (59.10 ± 5.25–62.03 ± 1.77%). The cytotoxicity of pointed gourd and its peel was higher while moringa leaves demonstrated lower toxicity. Conclusion: Considering the inhibition rate and cytotoxicity, pointed gourd ethanol extract (Inhibition: 67.43 ± 11.80%; Cytotoxicity: 209.98 μg/mL) would be the best candidate for managing postprandial hyperglycemia.
