Two cytotoxic triterpenes have been isolated from Euphorbia pulcherrima. Their structures and stereochemistry have been established from NMR, IR, and EI-mass spectroscopy. The compounds were identified as 9,19-cycloart-23-ene-3 beta,25-diol and, 9,19-cycloart-25-ene-3 beta,24-diol. Cytotoxicity evaluation was performed using Ehrlich ascites tumor cells… CONTINUE READING
