Chemical constituents from Gastrodia elata (II) / 中草药

ABSTRACT

Objective: To study the chemical constituents of Gastrodia elata. Methods: The compounds were separated and purified by column chromatography and their structures were established by spectroscopic methods. Results: Nine compounds were isolated from the 50% ethanol extract of G. elata, whose structures were determined as 1-furan-2-yl-2-(4-hydroxy-phenyl)-ethane-1, 2-dione (1), 2, 4-bis (4-hydroxybenzl)-phenol (2), 4-(methoxymethyl) phenyl-1-O-β-D-glucopyranoside (3), 1-furan-2-yl-2-(4-hydroxy-phenyl)- ethanone (4), parishin B (5), parishin C (6), {1-[4-(β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyloxy) benzyl], 2-[4-(β-D-glucopyranosyloxy) benzyl]} citrate (7), bis (4-hydroxybenzyl) sulfide (8), and di-(p-hydroxybenzy1) disulfide (9). Conclusion: Compound 1 is a new compound, named gastrofurodione, and compound 9 is isolated from this genus for the first time.
