Abstract

In this study, chemical composition, fatty acid (FA) profile and oil characteristics of seeds of Salvia leriifolia Benht collected from different regions of Iran. All samples were rich in oil (24-28.5% dry weight basis), protein (24.5-28.5%) and crude fiber (13.1-16.6%). The mean values for Ca, P, K, Mg, Fe, Mn, Cu, Na and Zn were found at the levels of 3866, 2970, 3141, 2584, 57, 18.5, 9.0, 10 and 18.5 mg/kg, respectively. Iodine value varied from 83 to 107 which indicated level of unsaturation extracted oils. Saponification number, acid value, peroxide value and refractive index varied from 177 to 198, 0.70 to 1.36, 0.80 to 1.01 and 1.448 to 1.460 respectively. Fatty acids (FA) analysis revealed that oleic acid from 39.6% to 44.9% and linoleic acids from 41.1% to 44.4 were the main unsaturated FA. Palmitic acid (11.3-13.5%) is also the main saturated FA and alpha linolenic acid was found at trace levels (lower than 2%). The results showed that the seeds of all six S. leriifolia can be a good source of edible oil.
