The aim of this work was to analyze physicochemical characteristics and fatty acid profile of seed oil of Lavandula bipinnata. The total lipid content of L. bipinnata seed was 27.2%. The oil was liquid at room temperature, with a specific gravity and refractive index of 0.971 and 1.480 respectively. The acid value (5.764 mg NaOH/g), saponification number (188.75 mg KOH/g), ester value (182.98 mg KOH/g), iodine value (169.2 mg/100 g), free fatty acid (2.88) and peroxide value (7.62 mq/kg) were comparable with that of sunflower oil. The seed oil possess high concentration of linolenic acid (66.25%) followed by linoleic (18.05%), oleic (7.20%) and palmitic (5.46%). L. bipinnata seeds accumulate a high amount polyunsaturated fatty acid (84.31%) and a monounsaturated fatty acid concentration of 7.29%. The seed oil failed to possess any antagonistic activity against the tested bacteria but a radical scavenging activity (IC50) of 8.15 μg/μl was observed against DPPH.
