In the present study, six new compounds namely, picralactones CH (1-6) along with nine known compounds (7-15) were isolated from the branches and leaves of Picrasma chinese P.Y. Chen. Their structures were determined with the help of spectroscopic techniques such as NMR, HR-ESI-MS, UV, IR and CD. Cytotoxicity of all compounds was evaluated against MDA-MB-231, SW-620 and HepG2 human cancer cell lines. Compound 4 showed cytotoxic activities.
