Six compounds were isolated from Dracaena cochinchinensis (Lour.) S.C. Chen. Their structures were identified as 2,3,5,6-tetracchloro-1,4-dimethoxybenzene (I), 7-hydroxy-4'-methoxyflavan (II), 4'-hydroxy-3,5-dimethoxystilbene (III), 4'-hydroxy-2,6-dimethoxydihydrochalcone (IV), 4'-hydroxy-2,4,6-trimethoxydihydrochalcone (V) and 6-hydroxy-7-methoxy-3-(4'-hydroxybenzyl) chromane (VI) by chemical method and spectral analysis. IV and VI are new compounds.
