Fatty acid composition of Sonchus arvensis L. roots

Shukla, Shipra ; Kumar, Anil ; Bahadur, Lal ; Pal, Mahesh


The roots of Sonchus arvensis L. were extracted with petroleum ether to afford the extract 2.39 % yield to the fresh weight of the material. The fatty acid methyl esters (FAME) was prepared from the extract and analyzed by GC and GC-MS. Eighteen fatty acids were identified and major fatty acids found to be Myristic acid (26.23 %), Palmitic acid (26.23 %), Linoleic acid (19.94 %), Pentadecanoic acid (3.11 %), Stearic acid (1.49 %), Behenic acid (1.27 %). The most abundant fatty acid identified was Myristic acid (26.23 %).
