Sea buckthorn oil
Sea buckthorn oil is derived from plants in a group of species of the genus ''Hippophae'', the most commonly used of which is ''Hippophae rhamnoides''. As species belonging to this genus accumulate lipids in the mesocarp (the fleshy part of the fruit),〔 oil can be extracted from either the seeds or the pulp of the fruit.
==Chemical constituents==
Oil content in seeds of sea buckthorn is on average 7-11 % while oil content of pulp is around 1.5-3 % (per fresh weight). Seed oil is characterized with high contents of polyunsaturated fatty acids〔 while pulp oil contains monounsaturated fatty acids〔 and carotenoids. Both oils also contain dense amounts of tocopherols, tocotrienols and plant sterols.
===Fatty acids===
Oils from sea buckthorn seeds and pulp differ considerably in fatty acid composition. While linoleic acid and α-linolenic acid are the major fatty acids in seed oil, sea buckthorn pulp oil contains approximately 65% combined of the monounsaturated fatty acid, palmitoleic acid, and the saturated fatty acid, palmitic acid.〔 Few other vegetable oils contain a similar quantity of these fatty acids.
