Abstract

Seabuckthorn (Hippophae spp.) is widely distributed shrub of the cold Himalaya region with multiple medicinal properties. In the present article, we investigate some physicochemical parameters of the H. Salicifolia grown in the higher altitude of Himalaya where plants were grown in natural condition. We evaluate the oil content from its fruit via Soxhlet extraction and studied its parameters such as Acid value, Free fatty acid %, Density, refractive index and Total soluble sugar, Vitamin C concentration and Carotenoid content. Besides that, esterification of oil was also done to analyze the chemical components present in its oil via GC MS. For this purpose seeds were collected from the DIBER field station Auli (Joshimath), Oil percentage was almost 11% using hexane as a solvent which has the acid value of 9.23 mg KOH/g. The density of oil was 853 Kg/m3, Refractive index was found 1.82 these two are specific stable identification for the oil. Further to this, the GC-MS study revealed that important chemical constituents were found are Docosanol, ß Sitosterol, Phytol and cis-linoleic acid. The result revealed the capability of H. salicifolia seed oil for medicinal purpose and for the food purpose.
