title: Two new triterpenoids from Callicarpa kwangtungensis.
abstract: Two new triterpenoids, 2α,3β,16α,19α,23-pentahydroxyolean-12-en-28-oic acid (1) and 2α,3α,11α,21α,23-pentahydroxyurs-12-en-28-oic acid (2), were isolated from the aerial parts of Callicarpa kwangtungensis. Their structures were elucidated by 1D and 2D analyses, as well as MS and IR spectra.
