STUDIES ON THE CHEMICAL COMPONENTS OF FRUITS OF CHINESE SEABUCKTHORN

Chinese Seabuckthorn (Hippophae rhamnoides subsp. sinensis) mainly distributes in the Loess plateau region of China. The result given by analysing the Chinese Seabuekthorn fruits demonstrates: fresh fruit contains 73.6% water, 738.2mg/100g Vitamin C(variation range: 378.0—1319.6mg/100g), 4.6—13.5mg/100g carotene, 3.23—5.30% organic acid, 5.2—12.7% soluble sugar; Malic acid is 67—71% by organic acid, glucose is 49.6% by soluble sugar and fruetose is 48.2% Seed is 5.8—7.9% by fruit weight. Fruit pulp contains 2.05% oil and seed contains 8.36% oil. The main factor influencing the change of chemical components is growing habitat, especially the light conditions, and the types of fruit colour.Oil of fruit pulp contains 54.0—102.6mg/100g carotene, 40.1—61.8mg/100g Vitamin E, 32.8% saturated fatty acid and 66.8% unsaturated fatty acid Oil of seed contains 27.8mg/100g carotene, 65.7—104.0mg/100g Vitamin E, 11.0% saturated fatty acid and 88.9% unsaturated fatty acid. There is a great capacity of Vitamin E and carotene in the oil of Chinese Seabuekthorn fruits, which is very precious.
