The pentacyclic triterpene Esters and the free, esterified and glycosylated sterols of Sorghum vulgare grain

Abstract

The free, esterified and glycosylated sterols and triterpene esters of Sorghum vulgare grains were analysed by GLC. 4-Demethylsterols were found free, esterified and glycosidated. 4-Monomethyl-sterols were found completely free whilst the triterpenes were completely esterified. Three quarters of the total sterols in the grain were located in the embryo whilst the triterpenes were equally distributed between the embryo and endosperm.
