Abstract

Six phenylnaphthlene-type (1, 3~7) and a spirocycloyclohexadienone-type (8) neolignans, adihydronaphthalene dione (2), and a sesquiterpenoid derivative (9) were isolated from the bioactive fraction of the roots of Vitex negundo L (Verbenaceae). Their structures were elucidated by extensive spectroscopic analysis including 1D and 2D NMR and MS. Among them, compounds, 1 and 2, were identified as new isolates from natural products.
