摘要
目的:建立金银花中金属元素与总黄酮的含量测定方法。方法:用原子吸收分光光度法测定金银花中宏量元素钠、钙、镁、钾和微量元素铁、锰、铜、锌、铬、镍等金属元素的含量;用紫外分光光度法测定总黄酮的含量。结果:金银花中含有丰富的金属元素和黄酮类化合物。结论:本方法简便、快速、准确、灵敏度高、精密度好。
OBJECTIVE： To establish methods for the determination of the metal elements and the Total flavonoids in Flos Lonicerae Japonicae. METHODS： The atomic absorption spectrometry was adopted to determine the contents of macroele- ments （Na, K, Ca, Mg） and trace elements （Cu, Zn, Fe, Mn, Cr, Ni） while UV spectrometry was adopted for the determi- nation of the content of Total flavonoids in Flos Lonicerae Japonicae. RESULTS： Metal elements and Flavonoids were found to be rich in Flos Lonicerae Japonicae. CONCLUSION： The methods adopted in this study were simple, rapid, accurate, sensi- tive and precise.
