金菊花中微量元素和氨基酸的含量分析

The Determination of Trace Element and Amino Acids in Dendranthema Morifolium

目的研究金菊花干花中微量元素和氨基酸的含量及种类。方法利用原子吸收分光光度法和氨基酸自动分析法进行测定。结果金菊花含有丰富的Zn、Se、Fe、Cu等微量元素和7种人体必需的氨基酸,9种药用氨基酸和5种增香剂氨基酸,这3种氨基酸分别占氨基酸总量的38.7%、38.8%、26.9%,金菊花中游离氨基酸总含量达到9.83%。结论金菊花作为湖北一种道地药材,具有开发前景和应用价值。

Objective： To study on the trace element and amino acids of dried Dendranthema morifolium. Methods： In this study , atomic absorption spectrophotometry and the measure of automaticanalysing amino acids was used. Results.. Dendranthema morifolium Tzvel. contains four trace elements （zn, Fe, Se, Cu）, the seven humen essential amino acids, nine medicinal amino acids and five supplementary fragrance amino acids. The percentage of these three kinds of aminro acids in total ones are 38. 7, 38. 8 and 26. 9. The free amino acids has 9. 83 precent of weight in Dendranthema morif01ium Tzvel. Conclusion： Dendranthema morifolium Tzvel. as a genuine medicinal material has prosperous exploiting prospects and applied values.
