ABSTRACT
Chemical constituents of the dried aerial parts of Euphorbia nematocypha were investigated. A new oleanane triterpenoid, trans, trans-2',4'- hexadienedioicacid-1'-ß-amyrin ester (1), together with, ß-amyrin (2), ß-amyrin acetate (3), betulinic acid (4), ellagic acid (5), oleanolic acid (6), ß-sitosterol (7), kaempferol (8), quercetin (9), lupeol (10) and pseudo-taraxasterol (11) were isolated from the methylene chloride extract. Their structures were elucidated on the basis of extensive spectroscopic (1D- & 2D-NMR) and ESI-MS analysis and comparison with data reported in the literature. The new isolated triterpenoid showed moderate cytotoxic activities against HeLa and MCF-7cell lines.
