Article abstract of DOI:10.1016/0031-9422(81)85279-X

From the ether-soluble fraction of an extract of Sapium indicum two new nitrogen-containing esters of deoxyphorbol, sapintoxins B and C, were isolated.Both were characterized by the bright blue fluorescence which they exhibited in UV light.Sapintoxin B was identified as 12-(N-methylaminobenzoyl)-4-deoxy-5-hydroxyphorbol-13-acetate and sapintoxin C as 12-(N-methylaminobenzoyl)-4,20-dideoxy-5-hydroxyphorbol-13-acetate. -- Key Word Index - Sapium indicum; Euphorbiaceae; phorbol derivatives; N-methylaminobenzoyl esters; 4-deoxy-5-hydroxyphorbol; 4-20-dideoxy-5-hydroxyphorbol.
