小红参、人参果等中药微量元素含量及其临床意义探讨

用原子吸收分光光度法测定了小红参等11种中药中 Zn、Sr、Ni、Mn 等10种微量元素和 Ca 等3种宏量元素的含量。并据测定结果参考有关文献对小红参、人参果、茜草、柴胡、甘草等灰分率、元素含量和元素比值等特点的临床意义作了探讨。初步认为它们对防治某些心血管病、血液病和加强免疫、抗放射线、抗癌、抗衰老研究将有一定价值。

Determination of Trace Elements in Chinese Herbal Medicines Salvia yunnanensis etc.and Their Clinical Significance

Using atomic absorption spectrophotometry,amounts of 10 kinds of trace elements(Zn,Sr,Ni, Mn,Mg,Fe,Cu,Cr,Co and Al)as well as Ca,K and Na were determined in Salvia yunnanensis, Fructus et Radix Panax ginseng,Rubia cordifolia,Bupleurum chinense,Codonopsis pilosula, Astragalus membranaceus,Glycyrrhiza uralensis,Angelica sinensis Panax notoginseng and Salvia miltiorrhiza.All of the 13 kinds of essential metals for human were found in these 11 kinds of Chinese herbal medicines,with the only exception of Co not detected in Glycyrrhiza uralensis.The ash ratio and contents of Co,Cr,Cu,Fe,Ni and K were highest in Salvia yunnanensis.The quantity of Zn and Mn were very high in Salvia yunnanensis and were also rather high in Bupleurum chinense,Rubia cordifolia and Fructus Panax ginseng,The Sr content amounted to as high as over 200 ppm in Glycyrrhiza uralensis.The highest ratio of Zn/Cu was found in Fructus Panax ginseng,while the ratios of Ca/Mg and K/Na were highest in Panax ginseng.The clinical significance of the above- mentioned characteristics was discussed with a review of relevant literatures.The authors consid- ered that these Chinese herbal medicines could be of certain effects in preventing and treating cardiovascular and hematologic diseases and in immunoenhancement,radiation protection,anti- cancer and delay of aging.
