OBJECTIVE
To investigate the chemical constituents of the roots of Periploca forrestii and evaluate their cytotoxicity activities.
METHODS
Silica gel column chromatography was employed for the isolation and purification of chemical constituents. The structures were identified on the basis of spectral data and the cytotoxicities of compounds 2-4 were investigated by several tumors cell lines including blood tumor (HL-60, CCRT-CEM), prostate tumor (PC-3, DU-145) and Melanoma (UACC-62).
RESULTS
Four compounds were isolated and identified as follows, lupeol-20(29)-en-3-nonadecanoate (1), peroiforoside I (2), 3beta,5beta,14beta-3OH-8beta-H-car-20(22)-enolide (3), perplocin (4).
CONCLUSIONS
Compound 1 is a new lupane triterpene fatty acid ester. Compounds 2-4 showed notable cytotoxicity against all tumor lines.
