Triterpene alcohols and fatty acids in lipids and nonsaponifiable matter of Lapsana communis L. subspecies communis (Asteraceae)

摘要

The oil content of samples of aerial parts of L. communis subsp. communis, harvested in Indre et Loire (France) at different periods, was in the range 1.1-2.1%. Non-saponifiable matter in these samples represented 36-65.7% of the oil. Yields of triterpene alcohols, known to have antiinflammatory properties, in the nonsaponifiable matter (25.9-81.8%) were determined by preparative TLC after saponification. Seven of them were identified by GC-MS. Six of the fatty acids were also identified by GC-MS.The seeds of L. communis contained 2.6% oil.
