In this study, a new flavonoid glycoside was isolated from the heartwood of Toxicodendron vernicifluum, together with four known compounds. The new compound showed significant cytotoxicity against A549 cell lines.
Toxicodendron vernicifluum (Stokes) F.A. Barkley, also called 'Qishu', is a shrub belonging to the Anacardiaceae family and producing lacquer. In this work, a new flavonoid glycoside (1), was isolated from the heartwood of T. vernicifluum, together with four known compounds (2-5). The structure of the new compound was determined as 4 ',7-dihydroxy-3 '-methoxy-3-O-beta-D-glucopyranosyl-flavonoid (1), on the basis of acidic hydrolysis, and spectroscopic analyses. Compound 1 showed significantly cytotoxic against A549 cell lines with the values of IC50 at 1.5 mu M.
