Hippophae rhamnoides L. is a unique plant, since fruit is rich of vitamins and oil. We investigated vitamin content, fatty acid composition of oil and antioxidant activity in the berries harvested in Iwate prefecture (Rikuzen-takata city). Content of carotene and alpha-tocopherol of H. rhamnoides ssp. mongolica (Russian type) was higher than that of H. rhamnoides ssp. rhamnoides (European type). L-ascorbic acid showed no difference between these types. Both of these berries contained 2% oil, and linoleic and alpha-linolenic acids comprised about 20% of oil fatty acids. The proportion of palmitoleic acid was higher in the oil of berries of Russian type than the berries of European type. In contrast the proportion of oleic acid was higher in the oil of berries of European type than that of Russian type. Antioxidant activity of this berry was very high compared with other berries, and it was not correlated with polyphenol content, while vitamins were shown to be major activity sources of this berry.
