Abstract:
Objective: To study the chemical constituents of Dendrobium officinale in order to provide more scientific basis for its development and utilization of medicinal resources. Methods: The compounds were isolated and purified by repeated column chromatography with silica gel and ODS column, and semi-preparative HPLC. Their structures were identified by spectroscopic data. Results: Fourteen compounds were isolated from the 70% ethanol extract of D. officinale and identified as: benzyl-O-β-D- glucopyranoside (1), isorhamnetin-3-O-α-L-rhamnopyranosyl (1→2)-β-D-glycopyranoside (2), conicaoside (3), 3,4,5-trimethoxyphenyl- 1-β-D-glucopyranoside (4), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucoside (5), 4-(3'-hydroxypropyl)-2,6-dimethoxy-phenol- 3'-O-β-D-glcoside (6), thymidine (7), syringin (8), 4-allyl-2,6-dimethoxyphenyl glucoside (9), (+)-syringaresinol (10), syringaresinol- 4'-O-β-D-monoglucoside (11), naringenin (12), p-hydroxybenzoic acid (13), and 4,4'-dihydroxy-3,5-dimethoxybibenzyl (14). Conclusion: The compouds 1-6 are isolated from the species of Dendrobium Sw. for the first time, and 7-8 are isolated from D. officinale for the first time.
