Chemical studies of cyanolipids in Koelreuteria apiculata

Abstract

Many species of genus Sapindus (Sapindus saponaria [1], S. trifoliatus [2], Lepisanthes tetraphylla [3], S. obovatus [4, 9]) have been previously investigated for their cyanolipid content and all were found to contain only one type of cyanolipid, i.e. fatty acid diester of 1-cyano-2 hydroxymethylprop-1-ene-3- ol (II). Koelreuteria apiculata seed kernel oil has now been investigated and the oil is also found to contained the same type of cyanolipid.
