study the fatty acid composition and the physicochemical properties of salvia macrosiphon boiss seed oil

in this study, the oil yield, fatty acid (fa) composition and the physicochemical and quality characteristics of salvia macrosiphon crude seed oil were determined. the main fatty acids ranked in the following order of abundance: α- linolenic acid> linoleic acid> oleic acid. the n3 /n6 fa ratio and polyunsaturated fa/ saturated fa ratio were 1.6 and 7.23, respectively. the fa composition revealed that the oil had great potential to use as nutritional dietary component and also was very susceptible to oxidation. the physicochemical properties such as iodine ( 168.7 gi2/100g oil) , acidic ( 0.5) and peroxide ( 1.9) value, color ( l: 59.22, a: -5.09, b: 22.94) and refractive index (1.4723) were also determined. total phenol, tocopherol and sterol content were 165.22 mg ga/kg oil, 629.59 and 2540.6 ppm. in addition oxidative stability index was 3.94 h.
