A new ursane-type triterpenoid saponin from the aerial parts of Clematoclethra scandens subsp. actinidioides.[Pubmed: 25660290]


A new ursane-type triterpenoid saponin, 2α,3α,24-trihydroxyurs-12,20(30)-dien-28-oic acid β-D-glucopyranosyl ester (1), together with six known triterpenoid saponins, was isolated and characterized from the aerial parts of Clematoclethra scandens subsp. actinidioides.

To study the chemical constituents of Clematoclethra scandens subsp. actinidioides, chromatographic methods such as silica gel and MCI column chromatographic technology, and preparative HPLC were used and sixteen compounds were isolated from the aerial parts of this plant. By using spectroscopic techniques including 1H, 13C-NMR, HMBC and ESI-MS, these compounds were identified as betulinic acid (1), ursolic acid (2), oleanic acid (3), corosolic acid (4), 3beta-(trans-p-coumaroyloxy)-2alpha, 23-dihydroxyurs-12-en-28-oic acid (5), 3beta-(trans-p-coumaroyloxy)-2alpha, 23-dihydroxyurs-12, 20 (30)-dien-28-oic acid (6), 2alpha, 3alpha, 23-trihydroxyurs-12, 20 (30)-dien-28-oic acid (7), 2alpha, 3alpha, 23-trihydroxyurs-12-en-28-oic acid (8), asiatic acid (9), 2alpha, 3alpha, 24-tri-hydroxyurs-12-en-28-oic acid (10), 2alpha, 3beta, 23-trihydroxyurs-12, 20 (30)-dien-28-oic acid (11), 2alpha, 3beta, 19alpha, 24-tetrahydroxyurs-12-en-28-oic acid (12), 2alpha, 3alpha, 19alpha, 24-tetrahydroxyurs-12-en-28-oic acid (13), 2alpha, 3beta, 23, 24-tetrahydroxyurs-12-en-28-oic acid (14), 2alpha, 3alpha, 19alpha, 23, 24-pentahydroxyurs-12-en-28-oic acid (15) and daucosterol (16). Among them, compounds 3-6, 11-12, 14 and 15 were isolated from this endemic plant for the first time.
