Abstract:
Chemical constituents of n-butanol part of ethanol extract from the leaves of Cyclocarya paliurus (Batalin) Iljinskaja were studied.Eight glycosides were separated and purified by silica gel, MCI, ODS, Sephadex LH-20 column chromatography and semi-preparative high-performance liquid chromatography.Based on the physicochemical properties and spectral data, these compounds were 3-ethyl-4-methyl-pentyl ester-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (1), juglanoside E (2), (4S)-α-terpineol-8-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside (3), (4S)-α-terpineol-8-O-β-D-apiofuranosyl-(1→6)-β-D-glucopyranoside (4), eugenyl-O-β-D-apiofuranosyl-(1→6)-O-β-D-glucopyranoside (5), kaempferol-3-O-β-D-glucuronopyranosyl methylester (6), kaempferol-3-O-β-D-glucuronopyranoside (7), and quercetin-3-O-β-D-glucuronopyranoside (8).Among them, compound 1 was a new compound, and compounds 2-6 were isolated from the genus Cyclocarya for the first time.
