Popis: Extracts of Vetiveria nigritana flowering tops and rhizomes were analyzed by mean of GC/MS for their fatty acids and unsaponifiable components. In flowering tops extract, the acid fraction is characterized by the presence of palmitic acid and other long chain fatty acids (until C 34). Unsaponifiable contains a high percentage of sterols (43.89%, mainly b-sitosterol). In rhizomes extract, acid fraction is composed by a high amount of typical organic acids of the genus Vetiveria and by a low quantity of fatty acids. Unsaponifiable fraction is characterized by the presence of a great percentage of sesquiterpenic derivatives (54.8%), and of sterols in low amount (13.7%).
