To study the triterpenoids and triterpenoid saponins of Viscum liquidambaricolum further, chemical constituents were isolated from the title plant by various chromatographic methods such as silica gel and ODS medium pressure column chromatography, Sephadex LH-20 column chromatography, et al. Their structures were elucidated by physiochemical properties and spectral analysis. Eight triterpenoids and triterpenoid saponins were isolated and identified as myricadiol(1), maslinic acid(2), 2alpha, 3beta, 23-trihydroxyolean-12-en-28-oic acid(3), oleanolic acid 3-O-beta-D-glucuronopyranoside-6'-O-methyl ester(4), oleanolic acid 3-O-beta-D-glucuropyranoside(5), oleanolic acid 3-O-beta-D-glucopyranosyl-(1-->2)-alpha-L-arabinopyranoside (6), 3-O-beta-D-glucuronopyranosyl-oleanolic acid-28-O-beta-D-glucopyranoside (7), 3-O-beta-D-glucuronopyranosyl-oleanolic acid-28-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (8). Compounds 1-8 were isolated from this plant and the genus for the first time.
