摘　　要：以长白山野生高山红景天为试材,比较分析了必需氨基酸在不同性别高山红景天不同器官之间的分布差异。结果表明:高山红景天中测出的7种人体必需氨基酸中亮氨酸含量最高、占1/4,其它6种必需氨基酸分别占2.44%～17.39%;亮氨酸和苯丙氨酸在叶片中分布多,赖氨酸和苏氨酸在根中分布多,缬氨酸、异亮氨酸和甲硫氨酸的分布因性别而异;从不同性别来看,有亮氨酸和苏氨酸在雌株中、赖氨酸和甲硫氨酸在同株中、缬氨酸、异亮氨酸和苯丙氨酸在雄株中分布较多的趋势;高山红景天中测出的2种人体半必需氨基酸中精氨酸的含量远比组氨酸高。Using wild Rhodiola sachalinensis A.Bor of Changbai Maintain as material,the difference of essential amino acids distribution in different sexual and organs of Rhodiola sachalinensis A.Bor were comparisoned and analysised.The results showed that contained 7 kinds of essential amino acids for human body,in which leucine acid content was the highest（25%）and others essential amino acids were occupy from 2.44% to 17.39% of total amino.The content of leucine and phenylalanine acids were the highest in leaf.The content of lysine and threonine acids were the highest in root.The characteristics of distribution of valine,isoleucine and methionine acids varies by sexual.By sexual,leucine and threonine acids were in female plant,lysine and methionine acids were in hermaphrodite plant,the content of valine,isoleucine and phenylalanine acids were found to be higher in male plant,2 kinds of semi-essential amino acids for human were arginine and histidine acid.The content of arginine was obviously higher than histidine acid.
