摘　　要：对引进到拉萨的2种欧李材料(科尔沁和洛南)的果实及枝叶的营养成分、氨基酸和微量元素进行测定分析,为欧李在高海拔的开发利用提供理论依据。结果表明,科尔沁欧李果实的可溶性固形物、可溶性糖、总酸、还原糖、蛋白质、总氨基酸、必需氨基酸、微量元素含量均高于洛南欧李,但抗坏血酸、铁和锌含量相反;2种材料果实的天门冬氨酸和枝叶的谷氨酸在各类氨基酸中均达到最高,科尔沁欧李枝叶的总氨基酸、必需氨基酸、粗蛋白质、钙含量、半纤维素均高于洛南欧李,而洛南欧李枝叶的粗灰分、中性洗涤纤维、酸性洗涤纤维均高于科尔沁欧李。从2地引进的欧李枝叶中钙含量、氨基酸含量均远高于果实,其中枝叶中的钙含量约为果实的100倍。The nutrient components,amino acids and trace elements of fruits and branches of two Cerasus humilis Bunge materials(Horqin and Luonan)introduced to Lhasa were measured and analyzed,which provided a theoretical basis for the development and utilization of C.humilis at high altitudes.The results showed that the soluble solids,soluble sugars,total acids,reducing sugars,protein,total amino acids,essential amino acids and trace element contents of Horqin C.humilis fruit were higher than those of Luonan C.humilis,but the contents of ascorbic acid,iron and zinc were the opposite.The aspartic acid of fruits and the glutamic acid of the branches and leaves of two materials of C.humilis reached the highest among all kinds of amino acids.The total amino acids,essential amino acids,crude protein,calcium content and hemicellulose of the branches and leaves of Horqin C.humilis are higher than those of Luonan C.humilis.The crude ash content,neutral washing fiber,and acid washing fiber of Luonan C.humilis branches and leaves are higher than that of Horqin C.humilis.The contents of calcium and amino acids in the branches and leaves of Horqin and Luonan C.humilis were much higher than those in the fruits,and the calcium content in the branches and leaves was about 100 times that of the fruits.
