Flavonoids, triterpenoids and a lignan from Vitex altissima

A new lignan, altissinone (1), and a new flavonoid, 2″-O-p-hydroxybenzoylorientin (2), along with 11 known compounds have been isolated from ethyl acetate extractives of the leaves of Vitex altissima. The structures of these compounds were determined by 2D NMR data. The isolates were evaluated for their antioxidant and 5-lipoxygenase inhibitory activities.
