STUDIES ON THE CHEMICAL COMPONENTS IN FRUITS OF H. RHAMNOIDES

The chemical components of the fruits of three subspecies of Hippophae rhamnoides are reported in this paper. It is found that the contents of chemical components between the subspecies of H. rhamnoides at different locations vary significantly.The contents of chemical components in fresh fruits are: vitamin C 86.97-1897.38mg/100g, organic acids 1.21-8.12%, dissolvable saccharides 0.86-16%. The oil in absolute dry pulp is 2.53-38.65%. The composition of oil is 20-31% saturated fatty acids and 65-76% unsaturated fatty acids. The oil also contains vitamin E 100-200 mg/100 g and β-carotene 32.75-72.83 mg/100g. There are notable differences in vitamin C, dissolvable saccharides and oil in the fruits of the three subspecies, but no observable difference between H. rhamnoides L. subsp. sinensis Rousi and H. rhamnoides L. turkestanica Rousi,by means of "t" test. Besides, there are 17 kinds of amino acids and 26 kinds of mineral elements in H. rhamncides L. subsp. sinensis Rousi.
