Abstract
Vicia sativa L. (common vetch) is a potential food source for both human beings and animals because of its abundant nutritional composition. There is a lack of phytochemical study on the whole plant, and thus the objective of this study was to investigate the isolation of phytochemicals and evaluate their biological activities. A new flavanol, (2R,3S)-3,3′-dihydroxy-4′,7-dimethoxyflavanol (1), together with nine known compounds, two flavones (2–3), one coumarin (4), and six oleanane triterpenoids (5–10), was obtained from Vicia sativa L.. The structure of the new compound 1 was determined via its NMR spectra, IR and CD data. Compound 3 displayed the potential of the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging effect in antioxidant test. In terms of cytotoxic activities, compound 3 showed moderate cytotoxic activities against three human tumor cells, especially HeLa cells.
