Chemical Constituents of Vitex trifolia Leaves

Using various chromatographic methods, one new lanostane triterpene, 3α-hydroxylanosta-8,24E-dien-26-oic acid (1), one new lignan, matairesinol 4'-O-β-D-glucopyranoside (2) along with five known compounds, ecdysone (3), 20-hydroxyecdysone (4), 20-hydroxyecdysone 2,3-monoacetonide (5), turkesterone (6), and polypodine B (7) were isolated from the leaves of Vitex trifolia L. Their structures were elucidated by 1D-, 2D-NMR spectroscopic analysis, HR-ESI-MS, CD, and by comparing with the NMR data reported in the literature.
