“…Moreover, it can also further improve the resolution of unknown compounds, especially for poor chromatographic separation. The antioxidant capacity of foods plays an important role in the diet, which is related to anticancer and anti-aging effects, improvement in immune function, and the prevention of cardiovascular diseases and nervous system diseases [ 16 ]. Previous studies have indicated that MSCP had strong antioxidant activity [ 17 ] and anti-fatigue activity [ 18 ].…”

Millettia speciosa Champ. (MSCP) enjoys widespread recognition for its culinary and medicinal attributes. Despite the extensive history of MSCP cultivation, the disparities in quality and bioactivity between wild and cultivated varieties have remained unexplored. In this study, 20 wild and cultivated MSCP samples were collected from different regions in China. We embarked on a comprehensive investigation of the chemical constituents found in both wild and cultivated MSCP utilizing UHPLC-Q-Exactive Orbitrap-MS technology and multivariate analysis such as principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). In total, 62 chemical components were unequivocally identified or tentatively characterized. Via the multivariate statistical analysis, we successfully pinpointed nine compounds with the potential to serve as chemical markers, enabling the differentiation between wild and cultivated MSCP varieties. Moreover, both genotypes exhibited substantial antioxidant and anti-fatigue properties. The bioactivities of wild MSCP were marginally higher when compared to their cultivated counterparts. This study illuminates the impressive antioxidant and anti-fatigue potential present in both wild and cultivated MSCP genotypes, further augmenting the allure of this species and opening new avenues for the economic valorization of MSCP. Hence, this study provides a valuable method for the identification and quality control of MSCP and a method in chemistry and pharmacology to assess an alternative possibility for cultivated MSCP.

“…Antioxidants can be found in vegetables, fruits, cereals, most medicinal herbs, nuts, some meats, poultry, and fish (Nemzer et al, 2019;Jideani et al, 2021). Antioxidants are found naturally in foods and improve human health without causing harm, as opposed to synthetic antioxidants (Loizzo and Silva, 2021). It is the most effective method of protecting the body from free radical damage in an emergency.…”

This study was carried out in order to assess the biological efficacy of separated extracts of V. sessilis as an Antioxidant and antifungal against isolated candida spp. from diabetic foot ulcers. Several tests were used to identify the presence of active chemical compounds in V. sessilis and we note that the V. sessilis is rich in active substances. showed phytochemical results were found for the extracted ethanol 70% contain carbohydrates, flavonoids, phenols, alkaloids, glycosides, triterpenoid and saponin, and negative detection for Tannin, Steroid, and Amino acid. The antioxidant activity of V. sessilis extracts was assessed by decreasing the radical scavenging activity of (1,1-diphenyl-2-picrylhydrazyl (DPPH). Results exhibited that all extracts have antioxidant activity with different concentrations, showed the superiority of the polyphenol 86.02 % inhibition ratio at (1000 μg/ ml), flavonoid 84.05 % at (1000 μg/), and hexane extract 68.5 % at (1000 μg / ml) compared to ascorbic acid, which recorded 81.17% at a concentration of 1000 μg/ml. Whereas, the hexane extract recorded the lowest inhibition rate at (50 μg /ml). Efficacy showed of separated extracts from V. sessilis as antifungal activity using well diffusion plate method. The polyphenol extract (VP) was the highest activity against all isolated candida spp. from foot ulcers of diabetic patients, while the other extracts showed varying activity against different candida spp.at P. value < 0.01. The results that a high Zone rate of inhibition/mm 2 was (26.7 ± 0.6) against C. albicanis, while no inhibition/mm 2 (9.8± 0.8) for hexane extract against the same candida. HPLC analysis indicated the presence of 7 compounds in separated polyphenol extract of V.sessilis (Chlorogenic acid, Ferulic acid, Gallic acid, Rutin, Qurcetine, Kaempferol and Apigenin) with specific retention times. The detected compounds possess antioxidant and antimicrobial activities. These results suggested that separated extracts from V. sessilis have high antioxidant and antifungal activities. In the future, V. sessilis extracts could become one of the important alternatives in infection treatment, even if in a limited way due to the spread of candida spp. that are resistant to antifungals.
