Hippophae rhamnoides L. is a unique plant, since fruit is rich of vitamins and oil. Recently, it has been cultivated to obtain domestic berries. We investigated vitamin content, polyphenol and antioxidant activity of 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). In addition, juice from Russian type berries showed higher content of sugar and lower acidity than that of European type. The residue after squeeze of juice had a lot of oil. Antioxidant activity of berries was not correlated with polyphenol content, while vitamins were shown to be a major activity of berries.
