摘要
本文分析了我国豆科黄华族3属7种植物种子中的游离氨基酸组成,并初步讨论了其系统学意义。发现均含有较高的游离氨基酸,其总量的变化范围在2.792—12.51毫克/克干重之间,其中除谷氨酸和天门冬氨酸的含量均很高外,还发现含有很高的精氨酸,尤其是新疆黄华中精氨酸含量高达8.62毫克/克干重;属间、种间的游离氨基酸组成有着较大的差异,但不能完全反映出种属间的系统关系。
The total seed free amino acids for 7 species of Thermopsideae (Fabacae) of china range from 2.792 to 12.51 mg/g. dr. wt. Besides high contents of glutamic acid and aspartic acid, very high contents of arginine were also detected in all the species, especially in Thermopsis turkestaica. Although the free amino acid compositions are significantly different from one another, there is no obvious interrelation between free amino acid compositions and systematic relationships among this tribe
