Cyclopropenoid fatty acids in abutilon ramosum seed oil

Abstract

Seed oil of Abutilon ramosum was found to contain the following fatty acids (wt.%): malvalic (2.48%), sterculic (1.29%), myristic (1.0%), C15:0 (1.78%), palmitic (19.1%), palmitoleic (0.51%), stearic (6.53%), oleic (23.72%), linoleic (42.55%) and linolenic (0.91%). The qualitative and quantitative analysis of the fatty acids were carried out by HBr-titration and the gas-liquid chromatography of the silver nitrate-methanol-treated esters using the fatty acid esters of the oil of sterculia foetida as reference standard.
