title: [Constituents of the petroleum ether and ethyl acetate extract fractions from Dracaena cochinensis (Lour.) S.C. Chen].
abstract: Six constituents have been isolated from the petroleum ether and ethyl acetate extract fractions of Dracaena cochinensis. Their structures have been identified as 1,2,4,5-tetrachloro-3,6- dimethoxy-benzene,docosyl alcohol, octadecyl acetate, eicosyl acetate, resveratrol and 4',7-dihydroxy-flavone on the basis of physical, chemical and spectral deta. Of these compounds 1,2,4,5-tetrachloro-3,6-dimethoxy-benzene is a new one.
