The study was carried out to evaluate the physico-chemical characteristics and fatty acid profiles of seed and pulp oils of Sea-buckthorn (Hippophae rhamnodes L) wildly grown in Northern Areas of Pakistan (Skardu). The yield of oils from seed and pulp were 10% and 4.5% respectively. Physical characteristics i.e. specific gravity, refractive index, acid value, iodine value, saponification value and unsaponified matters were determined according to standard procedures. The unsaturated fatty acid in seed oil is (85%) and in pulp oil, is (63.4%) while saturated fatty acid in seed oil is (14.1%) and in pulp oil, is (36.0%) respectively. The GLC analysis of methyl esters derived from the seed oil of Sea-buckthorn revealed the presence of Palmitic acid (11.1%), Palmitoleic acid (9.8%), Stearic acid (2.6%), Oleic acid (Including Vaccenic acid) (22.1%), Linoleic Acid (29.6%) and alpha- and gamma-Linolenic Acid (23.4%). In pulp oil of Sea-buckthorn (H. rhamnodes L) we have Palmitic acid (34.5%) Palmitoleic acid (33.4%), Stearic acid (1.5%), Oleic acid (Including Vaccenic acid) (15.3%), Linoleic Acid (12.5%) and alpha- and gamma-Linolenic Acid (2.3%).
