Isolation and characterisation of cytotoxic compounds from Euphorbia clementei Boiss.

A new phorbol-type diterpene ester, 4,20-dideoxy-4α-phorbol-12β-acetate-13α-isobutyrate, in addition to 11 known compounds were isolated from the latex and roots of Euphorbia clementei Boiss. Structure elucidation was performed by comprehensive 1D and 2D NMR analyses (1H and 13C NMR, COSY, ROESY, HSQC and HMBC experiments), mass spectrometry (HR-ESI-MS) and… CONTINUE READING
