Abstract: This study presents nutritional and antimicrobial characteristics of seabuckthorn seed oil, extracted from berries of Hippophae salicifolia (4.3-4.9%) and H. rhamnoides (4.75-5.25%). Physicochemical analysis of seed oil gave: acid value, 4.0-4.7 mg KOH/g; saponification value, 184.3-230.2 mg KOH/g; peroxide value, 17.5-18.3 meq/kg; and unsaponifiable matter, 0.60-0.78%. The oil contained oleic acid (31.8-37.0%), linoleic acid (25.8-27.9%) and linolenic acid (14.1-17.8%), and thus showed predominance of unsaturated fatty acids (82.6-83.5% w/w) comprising of both polyunsaturated fatty acids (39.9-45.8% w/w) and monounsaturated fatty acids (36.9-43.6 % w/w). Seeds of both species contained vitamin E (27.0-30.0 ìg/g). Seed oil exhibited good antimicrobial property (growth inhibition zone diam, 4.0 mm) against Escherichia coli. Thus, owing to high content of linolenic acid and vitamin E and good antimicrobial property, seed oil can be exploited in pharmaceutical, cosmetic and nutraceutical preparations. Seed cake was rich in proteins and minerals and can be used as animal feed.
