Pistacia vera, Anacardiaceae, Phytoglycolipids. Seeds Two phytoglycolipids (PGL1 , PGL2), which in qualitative composition of their long-chain bases, sugar components and fatty acids show a close similarity with the phytoglycolipids of other plant seeds, were isolated from the pistacchio seeds (Pistacia vera L .) . The saccharid chain contain inositol, glucuronic acid, glucosamin, mannose, galactose and arabinose. The major fatty acids were the saturated 2-hydroxy C22 , C23 and C24 acids; the major long-chain bases were dehydrophyto-sphingosine and phytosphingosine. PGL1 should posses the typical groundstructure of the seed phyto­ glycolipids. PGL2 seems to contain a saccharid chain formed slight differently.
