摘　　要：沙棘是胡颓子科(Elaeagnaceae)沙棘属(Hippophae)的灌木或小乔木。我国是沙棘中心产区,在“三北”地区和西南各省(区)均有天然分布。我国共有四种沙棘:即鼠李沙棘(H.rhamnoides L.)西藏沙棘(H.thibetan Schlechtend.)、柳叶沙棘(H.salicifolia D.Don.)和肋果沙棘(H,neuvocarpas W.Lineet T.N.He)。因沙棘果实含多种维生素、有机酸、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. turkest-anica 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.
