title: One new dihydrobenzofuran lignan from Vitex trifolia.
abstract: A new benzofuran-type lignan, vitrifol A (1), was isolated from the fruits of Vitex trifolia, along with three known compounds 2-4. Their structures were elucidated mainly on the basis of 1D, 2D NMR and MS spectral data. Compound 1 was first isolated as a dimer of dihydrobenzofuran-type lignan.
