Four New Triterpenoids from Callicarpa kwangtungensis
AbstractFour new triterpenoids which were identifed as 2α,3β,6β,19α-tetrahydroxy- oleanolic acid 28-O-β-D-glucopyranoside (1), 2-O-β-D-glucopyranosyloxy-3α,19α-di-hydroxyoleanolic acid (2), 2-O-β-D-glucopyranosyloxy-3α,19α-dihydroxyursolic acid (3), 2α,3α,6β,19α-tetrahydroxyursolic acid 28-O-β-D-glucopyranoside (4), were isolated from the aerial parts of Callicarpa kwangtungensis together with three known triterpenoids identified as 2α,3β,21β-trihydroxyursolic acid 28-O-β-D-glucopyranoside (5), 2α,3α,19α,23-tetrahydroxyoleanolic acid 28-O-β-D-glucopyranoside (6), 2α,3α,19α,23-tetrahydroxyursolic acid 28-O-β-D-glucopyranoside (7). Their structures were elucidated by the combination of mass spectrometry (MS), one and two-dimensional NMR experiments. View Full-Text
