There are many types of this oil, depending on what part of the plant is used to extract oil.
Sea buckthorn seed oil : This is extracted specifically from the seeds inside the berries.
Sea buckthorn pulp oil : This is taken from the berry pulp, discarding the seeds.
Berry with Seeds oil : This is the most common form of sea buckthorn oil which is made from whole berries, including the seeds.
All these oils have moderate differences in terms of their nutrition value, their color and aroma. They however have quite similar properties because they all come from the same plant.
Sea buckthorn berry has very impressive nutritional profile. It contains over 190 nutrients and phytonutrients, including vitamin C, which is 12 times higher than that of an orange. It also contains high amounts of vitamins, minerals, fiber, and protein, making it a powerful superfood. This berry also has as much vitamin E as wheat germ, three times more vitamin A than carrots, and four times more superoxide dismutase (SOD), an important enzyme that helps prevent free radical damage, than ginseng. Plus, it’s the only plant source that contains omega 3, 6, 9, and 7.
Both sea buckthorn seed and fruit oil are rich in nutrients such as carotenoids, tocotrienols, and tocopherols. They are loaded with antioxidants like phenols, terpenes, and glucosides; vitamins A, C, and E; beta-carotene; plant sterols; and trace elements such as copper, iron, selenium, and manganese.
There is a major difference between the fatty acid composition of the two sea buckthorn oils. The major fatty acids in seed oil are omega 3 and 6, particularly linoleic acid and alpha-linoleic acid (comprising 70 percent). Meanwhile, the fruit oil contains monounsaturated fatty acids and omega 7 (palmitoleic and palmitic acid).
