OBJECTIVE
To study the chemical constituents of ethanol extract from dried roots of Euphorbia fischeriana.
METHODS
Compounds were separated by column chromatography with silca gel and elucidated by chemical evidence and spectral analysis.
RESULTS
Isobauerenyl acetate, beta-amyrin acetate,
Chemical constituents of the dried aerial parts of Euphorbia nematocypha were investigated. A new oleanane triterpenoid, trans, trans-2',4'- hexadienedioicacid-1'-β-amyrin ester (1), together with, β-amyrin (2), β-amyrin acetate (3), betulinic acid (4), ellagic acid (5), oleanolic acid (6),
