Four known lupane-type triterpenoids, glochidonol (1), glochidiol (2), lup-20(29)-ene-1beta,3beta-diol (3) and glochidone (3) were isolated from the stem bark of Glochidion zeylanicum. Previously, lupeol (5), lup-20(29)-ene-3beta,24-diol (6) and betulin (7) were isolated from the stem bark of
Eight oleanane-type saponins, glomerulosides A-H, were isolated from leaves of Glochidion glomerulatum. All isolated compounds were evaluated for cytotoxic activity on four human cancer cell lines, A-549, HT-29, OVCAR, and MCF-7. Glomerulosides C and E, which contain a benzoyloxy group at C-22,
Combined chromatographic methods led to the isolation of two new triterpenoid saponins, glochieriosides A and B (1, 2), from the aerial parts of Glochidion eriocarpum, along with three known triterpenes, glochidone (3), lup-20(29)-en-3beta,23-diol (4), and lup-20(29)-en-1beta,3beta-diol (5). The
Six known lupanes lupenone ( 1), 3- epi-lupeol ( 2), glochidone ( 4), glochidonol ( 5), glochidiol ( 6) and lup-20(29)-ene-1beta,3beta-diol ( 7) were isolated from the roots and stem wood of Glochidion eriocarpum and three, 5, 6 and lup-20(29)ene-3alpha,23-diol ( 3), were isolated from the roots and
The anticancer activity of ten compounds from the aerial parts of Glochidion eriocarpum were evaluated on two human cancer cell lines, HL-60 and HCT-116. Compounds 1-4 displayed highly potent cytotoxic activity on the HCT-116 cancer cell line with IC(50) values ranging of 0.41∼1.16 μM. Compounds 1-4
Five new oleanane-type saponins, hirsutosides A - E, were isolated from the leaves of Glochidion hirsutum (Roxb.) Voigt. Their structures were elucidated as 21β-benzoyloxy-3β,16β,23,28-tetrahydroxyolean-12-ene 3-O-β-d-glucopyranoside (1), 21β-benzoyloxy-3β,16β,23,28-tetrahydroxyolean-12-ene
