OBJECTIVE To study the chemical constituents from the roots of Ardisia crenata var. bicolor. METHODS The 70% ethanol extract from A. crenata was isolated and purified by silica, Sephadex LH-20, ODS, and preparative RP-HPLC, then the structures of obtained compounds were identified by physicochemical properties and spectral data. RESULTS Twelve compounds were isolated and identified as isolariciresinol-3α-O-β-D-glucopyranoside (1), isolariciresinol-4-O-β-D-glucopyranoside (2), lyoniresinol (3), lyoniside (4), isolariciresinol (5), lyoniresinol-3α-O-β-D-glucopyranoside (6), psychotrianoside G (7), pridentigenin E (8), 3β-O-{β-D-glucopyranosyl-(l→2)-α-L-arabinopyranoside}-cyclamiretin A (9), ardisimamilloside H (10), 3β-O-{α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl(1→4)-α-L-arabinopyranosl}-3β-hydroxy-13β,28-epoxy-16α-hydroxy-30-al (11), foegraecumoside L (12). CONCLUSION Compounds 1-6 and 12 are isolated from Ardisia for the first time,and compounds 1-9, 12 are isolated from this plant for the first time.
