Abstract:

An N-alkylamide profiling from an ethanolic Anacyclus pyrethrum DC. root extract was performed using a gradient reversed phase high performance liquid chromatography/UV/electrospray-ionization ion-trap mass spectrometry (HPLC/UV/ESI-MS) method on an embedded polar column. MS1 and MS2 fragmentation data were used for identification purposes while UV was used for quantification. Thirteen N-alkylamides (five N-isobutylamides, three N-methyl isobutylamides, four tyramides and one 2-phenylethylamide) were detected. Six of them, identified as undeca-2E,4E-diene-8,10-diynoic acid isobutylamide, undeca-2E,4E-diene-8,10-diynoic acid N-methyl isobutylamide, tetradeca-2E,4E-diene-8,10-diynoic acid tyramide, deca-2E,4E-dienoic acid N-methyl isobutylamide, tetradeca-2E,4E,XE/Z-trienoic acid tyramide and tetradeca-2E,4E,XE/Z,YE/Z-tetraenoic isobutylamide, are novel compounds which have never been reported before from Anacyclus pyrethrum.
