Constituents of Essential Oil and Lipid Fraction from the Aerial Part of Bupleurum scorzonerifolium Willd. (Apiaceae) from Different Habitats.

The essential oils and lipid fraction extracted from the aerial parts of were determined by a GC-MS method. In total, up to 67 components were identified. --Ocimene, --ocimene, limonene, -pinene, -copaene, -elemene, and caryophyllene oxide were recognized as consistent components of the essential oil extracted from the aerial parts of , regardless of the habitat. The content of these components varied from traces to a significant amount. The volume of the lipid fraction varied from 2.73 to 9.38%. In total, 23 components were identified, including 20 fatty acids, two sterols, and one ketone. The major fatty acid components identified were 16:0, 18:2n9, and 18:1n9. The total content of these fatty acids reached up to 76.19%. The lipid fraction of the aerial parts of predominantly contained MUFA and PUFA, which confirmed the pharmacological value of the species. The main factors affecting the composition of essential oils and lipid fractions of are environmental ones that determine the moisture supply to the plants in semiarid and arid areas.
