This study evaluated the potential antioxidant and antidiabetic properties in vitro of four millet grain varieties cultivated in South Korea. The free fractions were tested for their total antioxidant capacity using 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS+) and 2,2′-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays, followed by α-glucosidase, α-amylase, and advanced glycation endproducts (AGEs) formation inhibition assays. The total phenolics, flavonoids, and condensed tannins in the free fractions ranged from 107.8 to 136.4 mg ferulic acid equivalent (FAE)/100 g, 101.3 to 115.8 mg catechin equivalent (CE)/100 g, and 17.65 to 59.54 mg catechin equivalent (CE)/100 g, respectively. Finger Italian millet had the highest total phenolic content (136.4 mg FAE/100 g) and flavonoid content (115.8 mg CE/100 g). Barnyard and finger Italian millet showed the highest DPPH (IC50 = 359.6 µg/mL and 436.25 µg/mL, respectively) and ABTS radical scavenging activity (IC50 = 362.40 µg/mL and 381.65 µg/mL, respectively). Similarly, finger Italian millet also exhibited significantly lower IC50 values for the percentage inhibition of α-glucosidase (18.07 µg/mL) and α-amylase (10.56 µg/mL) as compared with acarbose (IC50 = 59.34 µg/mL and 27.73 µg/mL, respectively) and AGEs formation (33.68 µg/mL) as compared with aminoguanidine (AG) (52.30 µg/mL). All eight phenolic compounds identified in finger Italian millet were flavonoids, with flavanols being the predominant subclass. Taken together, millet flavonoids play important roles in the prevention and management of type 2 diabetes, and hence finger Italian millet has the potential to be developed as a functional food.

Cleome Arabica

The aim of this study was to evaluate the antioxidant capacities of Cleome arabica leaves’ extract collected on two seasons in the town of Laghouat steppe region of Algeria. Five common tests for measuring antioxidant capacities were used to compare with three standard antioxidants: measurement of free radical scavenging activity with 1,1-diphenyl-2-picrylhydrazyl radical (DPPH·) and 2,2ʹ- azinobis(3-ethylbenzo-thiazo-line-6-sulfonate) (ABTS·+) radical cation, measurement of total antioxidant capacities with phosphomolybdenum, ferric reducing, and cupric reducing methods. The amount of the phenolic compounds was carried out by the quantification of total phenolic, total flavonoid, and condensed tannin contents in three organic solvents with varying polarities. The results show that the ethyl acetate is the best extractor solvent of flavonoids, while petroleum ether has the ability to extract more of terpenes. The values of quantification ranged from 0.341 to 0.751 mg of gallic acid equivalent/g of dry matter, from 0.172 to 0.682 mg of quercetin equivalent/g of dry matter and from 0.172 to 0.332 mg of catechin equivalent/g of dry matter for the total phenolic, flavonoids, and the condensed tannins, respectively. All the extract shows strong antioxidant activity, whose best are found in the ABTS and DPPH assay with IC50 values of 0.01 and 0.017 mg/ml, respectively, in a different season. These results suggest that the level of antioxidant activity in this plant varies to a great extent. They also suggest that phenolics in this plant provide substantial antioxidant activity. Upon achievement of this survey, an extra benefit of this medicinal plant may be found.

Abstract Objectives Inhibition of carbohydrate absorption from intestine is an efficient way to prevent type 2 diabetes. Some edible plants have shown the potential as anti-diabetic agents by inhibiting carbohydrate-digestive enzymes in intestine. In terms of edible plant's health effect, bioactive compounds’ stability during the process of digestive enzymes has been commonly questioned. Therefore, the objectives of this study were to 1) examine inhibitory effect of garlic scape (GS), the green flower head of garlic on carbohydrate-degrading enzymes and 2) investigate antioxidant activity and total phenolic content (TPC) of GS treated with intestinal digestive enzymes. Methods GS extract (GSE) was prepared with 80% methanol (v/v) by homogenization, sonication, and filtration, and evaporation. α-glucosidase, maltase, glucoamylase, sucrase, α-amylase inhibitory activities were determined by measuring glucose hydrolyzed from nitrophenyl-glucopyranoside, maltose, starch, sucrose, and starch, respectively. To prepare gastrointestinal enzyme-digested GSE, GSE was digested with pepsin and a pancreatin-bile solution. GSE and gastrointestinal enzyme-digested GSE were assessed for TPC using a Folin-Ciocalteu reagent and for total antioxidant and radical scavenging activities by the following methods, phosphomolybdeum, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods, respectively. Results GSE (20 mg/ml) showed 30%, 50%, and 42% inhibition on α-glucosidase, maltase, and glucoamylase enzyme activities, respectively. GSE (50 mg/ml) showed 55.1% DPPH radical and 5782 mg vitamin C equivalent (VCE)/g ABTS radical scavenging activities. Total antioxidant activity of the GSE (1.5 mg/ml) exhibited 2.76 mg VCE/g. Consistent with its antioxidant property, the GSE showed a dose-dependent increase in TPC. Gastrointestinal enzymatic treatment resulted in approximately 46% reduction in DPPH and ABTS radical scavenging activity, total antioxidant activity, and TPC of the GSE. Conclusions Garlic scape has the potential as a natural anti-diabetic agent. Garlic scape keeps beneficial effects after the process of intestinal digestive system.

Aim: Golden melon (Cucumis melo) is an annual herbaceous plant belonging to the family of Cucurbitaceae (Cucurbit). This study was carried out to evaluate the phytochemical composition and in vitro antioxidant activity of golden melon seed extract. Place and Duration of Study: The study was carried out between a period of July and August 2017 at Baking Milling Division, Federal Institute of Industrial Research Oshodi Nigeria.  Methodology: The crude methanolic extracts of the seed were tested for phytochemical and antioxidant activities according to standard analytical procedure. The antioxidant potential of the seed extracts was examined using different assays by determining total phenolic content, total flavonoid content, total antioxidant capacity. The free radical scavenging activities of the extract such as 1,1-diphenyl-2-picrylhydrazyl (DPPH)  radical scavenging activity,  in vitro lipid peroxidation, and nitric oxide (NO) scavenging assay were determined spectrophotometrically. Results: The phytochemical screening of the seed extracts revealed the presence of some secondary metabolites such as alkaloids, phenolic, steroids, flavonoids, terpenoids and cardiac glycosides. The total phenolic content of extract was found to be 29.39 mg/100 g while the amount of total flavonoid content was 20.67 mg/100 g. Scavenging ability was observed to increase in proportion to concentration for all the scavenging assays and at the highest concentration of              100 µg/ml. Total antioxidant capacity assay showed 19.44 mg per 100 g. This high scavenging ability in the seed extracts may be attributed to the presence of phenolic and flavonoids compounds in the extract. The DPPH free radical scavenging activity of 100µg/ml Cucumis melo extract was 75.20% ± 0.72 while the reference standard (Ascorbic acid) was 83.24% ±0.31. Lipid peroxidation inhibition ability of 100 µg/ml Cucumis melo extract was 87.18% ± 0.16 while the standard (ascorbic acid) was 94.96% ± 0.16 at the same concentration. Results obtained from this study showed that the nitric oxide scavenging ability of the extract was 80.50%±0.63 while the standard antioxidant was 85.94% ± 0.54. Conclusion: In all the assays, Cucumis melo extract showed maximum percentage of antioxidant potentials at 100 µg/ml. Additionally, golden melon seed possess appreciable amount of phenols and high antioxidant properties which could be explored and incorporated in functional food applications particularly in baked products.

Using natural products as antioxidant agents has been beneficial to replace synthetic products. Efforts have been made to profile the antioxidant capacities of natural resources, such as medicinal plants. The polyphenol content of Himalayan rhubarb, Rheum emodi wall, was measured and the antioxidant activity was determined using DPPH and ABTS+ assay, and the oxidative stress was assessed using SOD enzymatic assay. Five different solvent fractions, n-hexane, n-butanol, ethyl acetate, dichloromethane, and water, were used for screening the antioxidant capacity in effort to determine the optimum extraction solvent. The total phenolic contents for R. emodi fractions ranged from 27.76 to 209.21 mg of gallic acid equivalents (GAE)/g of dry weight. DPPH and ABTS+ assay results are presented into IC50 values, ranged from 21.52 to 2448.79 μg/mL and 90.25 to 1718.05 μg/mL, respectively. The ethyl acetate fraction had the highest antioxidant activity among other fractions. Also, n-butanol and water fractions showed significantly lower IC50 values than the positive control in DPPH radical scavenging activity. The IC50 values of SOD assay of fractions ranged from 2.31 to 64.78 μg/mL. A similar result was observed with ethyl acetate fraction showing the highest SOD radical scavenging activity. The study suggests that the ethyl acetate fraction of R. emodi possess the strongest antioxidant activity, thus the most efficient in extracting antioxidant contents. Moreover, a highly significant correlation was shown between total polyphenol content and antioxidant activity screening assays. The compounds related to the antioxidant activity of R. emodi were identified to myricitrin, myricetin 3-galloyl rhamnoside, and myricetin, which have not been reported in studies about R. emodi before.

Antidesma bunius (L.) spreng (Mamao) is widely distributed in Northeastern Thailand. Antidesma bunius has been reported to contain anthocyanins, which possess antioxidant and antihypertensive actions. However, the antidiabetic and antiglycation activity of Antidesma bunius fruit extract has not yet been reported. In this study, we investigated the inhibitory activity of anthocyanin-enriched fraction of Antidesma bunius fruit extract (ABE) against pancreatic α-amylase, intestinal α-glucosidase (maltase and sucrase), protein glycation, as well as antioxidant activity. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) chromatogram revealed that ABE contained phytochemical compounds such as cyanidin-3-glucoside, delphinidin-3-glucoside, ellagic acid, and myricetin-3-galactoside. ABE inhibited intestinal maltase and sucrase activity with the IC50 values of 0.76 ± 0.02 mg/mL and 1.33 ± 0.03 mg/mL, respectively. Furthermore, ABE (0.25 mg/mL) reduced the formation of fluorescent AGEs and the level of Nε-carboxymethyllysine (Nε-CML) in fructose and glucose-induced protein glycation during four weeks of incubation. During the glycation process, the protein carbonyl and β-amyloid cross structure were decreased by ABE (0.25 mg/mL). In addition, ABE exhibited antioxidant activity through DPPH radical scavenging activity and Trolox equivalent antioxidant capacity (TEAC) with the IC50 values 15.84 ± 0.06 µg/mL and 166.1 ± 2.40 µg/mL, respectively. Meanwhile, ferric reducing antioxidant power (FRAP) showed an EC50 value of 182.22 ± 0.64 µg/mL. The findings suggest that ABE may be a promising agent for inhibiting carbohydrate digestive enzyme activity, reducing monosaccharide-induced protein glycation, and antioxidant activity.

Some medicinal plants and their purified derivatives have demonstrated beneficial therapeutic potentials for many centuries. They have been reported to exhibit antioxidant activity, reducing the oxidative stress in cells and are therefore useful in the treatment of many human diseases, including diabetes and other non-communicable diseases. This study evaluated antioxidative activity and enzymatic (alpha-amylase and alphaglucosidase) inhibitory potentials of Gymnema sylvestre methanolic leaf extract (GSMLE) using standard methods. Phytochemical screening revealed the presence of alkaloids, tannins, saponins, steroids, terpenoids and flavonoids. The total phenolics and total flavonoids content in the extract were found to be 6.629±0.745 (µg/ml of catechol equivalent) and 0.004±0.0012 (µg/ml of quercetin equivalent) respectively. GSMLE was shown to have radical scavenging activity against DPPH (290.54 ± 39.72 %), hydroxyl radical (86.507 ± 23.55 %) and hydrogen peroxide (45.25 ± 25.23 %). The level of SOD was significantly decreased in H2O2 induced and H2O2+extract induced when compared with normal control (p<0.05); the level of GSH was significantly increased in H2O2 induced control and significantly decreased in H2O2+extract induced test when compared to normal control. GSH was also decreased significantly in H2O2+extract induced when compared to H2O2 induced control (p<0.05). The extract also demonstrated significant inhibition of alpha-glucosidase (IC50 182.26 ±1.05μg/ml) when compared with standard acarbose (IC50 189.52±0.46) and was more potent than the arcarbose on alpha-amylase inhibition with IC50 of 195.3±4.40 and 200.05±7.16 respectively. These findings may therefore, stress the potentiality of using Gymnema sylvestre as a natural remedy for the management of type 2 diabetes.

Plant In Vitro Culture

We combined machine learning and plant in vitro culture methodologies as a novel approach for unraveling the phytochemical potential of unexploited medicinal plants. In order to induce phenolic compound biosynthesis, the in vitro culture of three different species of Bryophyllum under nutritional stress was established. To optimize phenolic extraction, four solvents with different MeOH proportions were used, and total phenolic content (TPC), flavonoid content (FC) and radical-scavenging activity (RSA) were determined. All results were subjected to data modeling with the application of artificial neural networks to provide insight into the significant factors that influence such multifactorial processes. Our findings suggest that aerial parts accumulate a higher proportion of phenolic compounds and flavonoids in comparison to roots. TPC was increased under ammonium concentrations below 15 mM, and their extraction was maximum when using solvents with intermediate methanol proportions (55–85%). The same behavior was reported for RSA, and, conversely, FC was independent of culture media composition, and their extraction was enhanced using solvents with high methanol proportions (>85%). These findings confer a wide perspective about the relationship between abiotic stress and secondary metabolism and could serve as the starting point for the optimization of bioactive compound production at a biotechnological scale.
