A new meta-homoisoflavane, 10,11-dihydroxydracaenone C (1), together with 7,4'-dihydroxyflavone (2), 7,4'-dihydroxyflavane (3), 4,4'-dihydroxy-2-methoxychalcone (4), 4,4'-dihydroxy-2-methoxydihydrochalcone (5), 7,4'-dihydrohomoisoflavanone (6), 7,4'-homoisoflavane (7), lophenol (8), beta-sitosterol (9), stigma-5, 22-diene-3-ol (10), 1-(4'-O-beta-D-glucopyranosyl)benzyl-ethan-2-ol (11), 3,4-dihydoxy-1-allylbenezene-4-O-alpha-L-rhamnopyranosyl-(1 --> 6)-O-beta-D-glucopyranoside (12), 1-hydroxy-3,4,5-trimethoxybenzene-1-O-alpha-L-apiopyranosyl-(1 --> 6)-O-beta-D-glucopyranoside (13), and tachioside (14) have been isolated from the fresh stems of Dracaena cochinchinensis. Their structures have been established by spectroscopic analysis, especially by 2D NMR. This is the first time compounds 11, 13, 14 have been isolated from Dracaena.
