通过测定松科3个树种云南松、华山松和云南油杉针叶的氨基酸、粗蛋白、粗脂肪和总糖含量，进行相关数据分析。结果表明，3种针叶内均含有17种氨基酸；其氨基酸平均含量最高的是谷氨酸、天冬氨酸、精氨酸和苏氨酸，最低的是组氨酸、蛋氨酸和半胱氨酸；3种针叶各种氨基酸含量大小依次为云南松＞华山松＞云南油杉；3种针叶粗蛋白含量分别为11.37％、13.72％和7.28％；粗脂肪含量分别为6.18％、10.82％和2.76％，总糖含量分别为4.85％、6.54％和7.35％。在与其他针叶树种针叶比较的基础上，探讨了云南松和华山松作为医药原料和畜禽饲料的开发应用前景。%The content of amino acids , crude proteins, crude fats and total sugars in leaves of Pinus yunnanensis, Pinus armandii, Keteleeria evelyniana were analyzed .The results show that all 3 conifer needles contain 17 amino acids.The highest amino acids content in these 3 conifer needles were glutamic acid , aspartic acid, arginine, threonine and the lowest content were histidine , methionine, cysteine.The order of amino acids content in 3 coni-fer needles was Pinus yunnanensis>Pinus armandii>Keteleeria evelyniana.The contents of crude proteins in Pinus yunnanensis, Pinus armandii and Keteleeria evelyniana’ s leaf were 11.37 %, 13.72 % and 7.28 %, the con-tents of crude fats were 6.18%, 10.82% and 2.76%, the contents of total sugars were 4.85%, 6.54% and 7.35 % respectively.Compared with other conifers needles , future prospects were discussed for the needles as raw materials for medicine and feedstuff .
