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

Abstract

AbstractThe oil content of samples of aerial parts of Lampsana communis L. subsp. communis, harvested in Indre et Loire (France) at different periods, varies from 1.1 to 2.1%. Nonsaponifiable matter in these samples represents 36.0 to 65.7% of the oil. Yields of triterpene alcohols of nonsaponifiable matter (25.9 to 81.8%) were determined by preparative thin‐layer chromatography after saponification. Seven of them were identified by gas chromatography‐mass spectrometry (GC‐MS). Six of the fatty acids in the aerial parts have also been identified by GC‐MS. The seeds of L. communis contain 2.6% oil.
