Chemical composition of Essential oil from the leaves of two species of BaiJiangCao, Patrinia scabiosaefolia Fisch and Patrinia villosa (Thunb.) Juss.

摘要

The essential oil obtained by the hydrodistillation of the leaves of Patrinia scabiosaefolia Fisch and Patrinia villosa (Thunb.) Juss were analyzed by a combination of capillary GC-FID and GC/MS analytic techniques. 51 components comprising 94.56% of essential oil in leaves of P. scabiosaefolia Fisch and 33 components comprising 89.87% of oil in leaves of P. Villosa Juss were identified, respectively. The principal ingredients of oil from P. scabiosaefolia Fisch were 3-Methylbutanoic acid, Palmitic acid, Hexanoic acid and cis-Anethol and the principal ingredients of oil from Patrinia villosa (Thunb.) Juss were Camphogen, 2-Methyl-6-hydroxyquinoline, β-Damascenone and β-Ionone. Nine common components were confirmed in the essential oil of P. scabiosaefolia Fisch and P. Villosa Juss.
