对补肾等37味中药的生药及煎剂作了12种元素的检测,结果显示不同药物的元素组成差异很大,每药可能有其特殊的元素谱。但若按药物功能归类,则同类药物各元素的差异消失。生药中的元素并不能在煎煮过程中全部溶出,煎剂中的元素浓度远较生药中为低。故可认为金属元素在中药的药理机制中不占主导地位。但对中药中金属元素分析将有助于临床合理用药及防止医源性疾病的发生。
Twenty-six elements were tested for 37 herbs, such as Bushen and other herbal medicines and decoctions. The results showed that the elemental composition of different drugs varies greatly, and each medicine may have its own special spectrum. However, if the drugs are classified according to their functions, the differences between the elements of the same drugs disappear. The elements in the crude drug cannot be completely dissolved during the decoction process. The concentration of elements in the decoction is much lower than that in the crude drug. Therefore, it can be considered that metal elements do not dominate the pharmacological mechanism of traditional Chinese medicine. However, the analysis of metal elements in traditional Chinese medicine will help clinical rational use of drugs and prevent the occurrence of iatrogenic diseases.
