Lipids ofGlycyrrhiza glabra roots

A petroleum ether extract ofGlycyrrhiza glabra L. roots was investigated. The extract contains 70% neutral lipids and 30% polar lipids. Hydrocarbons, sterols esters, triacylglycerols, free fatty acids, free sterols, and diacylglycerols were identified. The fatty acid contents of all of the acyl-containing lipids were determined. Fourteen fatty acids were identified; the 18 ∶ 2 fatty acid prevails among the unsaturated acids, and the 16 ∶ 0 acid prevails among the saturated acids.
