摘　　要：对西双版纳天然林内小叶红光树、假广子和红光树的成熟种子进行脂肪酸成分分析.结果表明：3 个种共同含有的11 种脂肪酸总含量为96.51% - 99.27%,其中十四烷酸、十六烷酸和十八碳烯酸的总含量为90.85% - 95.24%.3 个种11 种脂肪酸含量具有高度的相似性.This study aimed to analyze the fatty acids of seeds of three Knema species (K. globularia, K. elegans and K. tenui-nervia ) in Xishangbannan of Yunnan province, China. The result showed that 11 kinds of fatty acids were consisted in Kne-ma globularia, K. elegans and K. tenuinervia simultaneously and their total percentage was in range of 96.51% to 99.27%, of which myristic acid (14∶0), palmitic acid (16∶0) and oleic acid (18∶1) accounted for 90.85% to 95.24%. The component pat-terns of fatty acids percentage were similar among the 3 species about the 11 kinds of fatty acids.
