Analytical characterization of Salicornia bigelovii seed oil cultivated in Pakistan

J Agric Food Chem. 2002 Jul 17;50(15):4210-4. doi: 10.1021/jf0114132.

Abstract

Seeds of Salicornia bigelovii (hybrid variety sos-10) were collected from five coastal areas of Pakistan on the Arabian Sea. Hexane-extracted oil content was 27.2-32.0%. Results of other physical and chemical parameters of the extracted oil were as follows: iodine value, 128.0-130.5; refractive index (40 degrees C), 1.4680-1.4695; unsaponifiable matter, 1.63-2.00%; saponification value, 178.6-189.0; density (30 degrees C), 0.9036-0.9074. Tocopherols (alpha, gamma, and delta) in the oil ranged up to 200 mg/kg. The S. bigelovii seed oil was found to contain high levels of linoleic acid (74.66-79.49%) and less oleic acid (12.33-16.83%). Saturated fatty acids, palmitic and stearic acids, ranged from 7 to 8.50% and from 1.24 to 1.69%, respectively. Linolenic acid (C(18:3) omega-3) was found within the range of 1.50-2.31%. The induction period (Rancimat, 20 L/h, 120 degrees C) of the crude oil was 1.40-1.70 h. Specific extinctions at 232 and 270 nm were 1.90-2.40 and 0.40-0.62, respectively. Many parameters of S. bigelovii seed oil were quite compatible with those of safflower oil.
