STUDIES ON THE PHENOLIC DERIVATIVES FROM GALEOLA FABERI ROLFE

Eight phenolic derivatives, p-hydroxybenzaldehyde (Ⅰ), 4,4'-dihydroxy-diphenyl methane(Ⅱ), 2,4-bis(4-hydroxybenzyl) phenol (Ⅲ), 5-methoxy-3- (2-phenyl-E-ethenyl)-2,4-bis (4-hydroxybenzyl) phenol(Ⅳ), p-hydroxybenzyl alcohol (V), 4-(β-D-glucopyranosyloxy) benzyl alcohol (gastrodin) (Ⅵ), bis-4-(β-D-glucopyranosyloxy) benzyl (S)-2-isopropylmalate (Ⅶ), his -4-(β-D-glucopyranosyloxy) benzyl (S)-2-sec-butylmalate(Ⅷ) were isolated from the rhizome of Galeola faberi Rolfe for the first time.Ⅳ and Ⅶ are new compounds. Ⅲ is a new natural compound.
