title: New Phenolic Derivatives from Galeola faberi.
abstract: Seven phenolic derivatives, 2,4-bis(4-hydroxybenzyl)phenol ( 1), bis[4(beta- D-glucopyranosyloxy)-benzyl] ( S)-(-)-2-isopropylmalate ( 2), bis[4-(beta- D-gluco-pyranosyloxy)benzyl] ( S)-(-)-2-sec-butylmalate ( 3), 4-hydroxybenzyaldehyde ( 4), 4,4'-dihydroxydiphenyl-methane ( 5), 4-hydroxybenzyl alcohol ( 6), and 4-(beta- D-glucopyranosyloxy)benzyl alcohol ( 7), were isolated from the rhizome of GALEOLA FABERI for the first time. Substance 1 is a new natural compound; 2 is identical with the previously isolated and characterised Substance V from GALEOLA SEPTENTRIOUS. It is accompanied in the plant here studied by the novel homologue 3. Their structures were established by chemical and spectral methods.
