【 摘 要 】

Habenarioside, a new natural product identified as [(2R)-2-[(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)oxy]-2-(2-methylpropyl)-1,4-dioxo-1,4-butanediyl]bis(oxymethylene-4,1-phenylene) bis-β-D-glucopyranoside, along with two known related metabolites, loroglossin and militarin, were isolated from the ethanol extract of the whole plant Habenaria petalodes Lindl. (Orchidaceae). The flavonoids isoquercitrin, isorhamnetin 3-O-β-D-glucopyranoside, and isorhamnetin 3,7-di-O-β-D-glucopyranoside were also isolated. The structures of all compounds were established by analysis of their MS, IR, UV, 1D and 2D NMR spectra, and comparison with published data.
