Chinese Journal of Natural Medicines, 2010, 8(4):260-3. | Four Triterpenoids with Cytotoxic Activity from the Leaves of Actinidia valvata[Reference: WebLink] | To study the chemical constituents of the leaves of Actinidia valvata Dunn. METHODS AND RESULTS: Several chromatographic methods were applied to isolate and purify compounds and their structures were elucidated by spectroscopic methods. Four triterpenoids including corosolic acid(1),2α,3β,24-trihydroxyurs-12-en-28-oic acid(2,3,24-Trihydroxy-12-ursen-28-oic acid
,2),2α,3α,24-trihydroxyurs-12-en-28-oic acid(3) and 2α,3α,19α,24-tetrahydroxyurs-12-en-28-oic acid(4) were isolated from Actinidia valvata Dunn.They all showed in vitro cytotoxic activity against tumor cell lines including PLC,Hep3B,HepG2,HeLa,SW480,MCF-7 and Bel7402. CONCLUSIONS: These 4 compounds were all obtained from the plant for the first time. |
