治疗呼吸系统疾病中草药微量元素含量测定

Determination of the Contents of Trace Elements in Chinese Herbal Medicines for Treating Respiratory System Diseases

微量元素与人体健康有密切的关系,各微量元素之间按一定比例存在,以维护各自的生理功能,如果比例平衡失调,疾病就可能发生或发展,中草药中含微量元素丰实。选取了16种临床上常用的治疗呼吸系统疾病的中草药百合、鱼腥草、甘草、板兰根、五味子、黄芩、贝母、何首乌、紫草、石菖蒲、半夏、银杏、金银花、葛根、柴胡和川芎,采用HNO3-HClO4湿法消化,用原子吸收分光光度计测定其Fe,Ni,Mn,Cr,Cu和Zn六种微量元素的含量,通过药物中微量元素含量的测定,观察不同药物中微量元素的含量差别。测定结果显示,16种中草药中微量元素含量丰富,含量较多的微量元素有Fe,Zn和Mn,不同药物中含量有所差别,含微量元素较丰富的是何首乌、银杏叶、柴胡、五味子、半夏和紫草;含量较少的葛根、石菖蒲和板兰根。分析结果为研究中药理论、药理药效等方面的深入研究提供了有效的参考数据。

There is an intimate connection between trace elements and body healthiness, trace elements and organism depend on each other, and each trace element exists with certain proportion, which preserve physio-function. If the balance is of maladjustment, diseases may occur or develop. The trace elements were determined in 16 kinds of Chinese herbal medicines by atomic absorption spectrometry. The medicines include lilium brownii, herba houttuyniae, licorice root, radices isatidis seu baphicacanthi, Sehizandra sinensis Bail, Scutellaria baicalensis Georgi, Beimu, Polygonum multiflorum Thunb, Lithospermum officinalel, Rhizoma acori grarnjnoi, Pinellia ternate Breit, Salisburia adiantifolia, Lonicera japonica, Radices puerarire, Bupleurum falcatum and Ligusticum wallichii, all of which could be bought on the market. Sixteen kinds of Chinese herbal medicines commonly used to treat respiratroy system diseases in clinic were selected, dried and powdered, completely mixed, 1. 000 0 g was weighed accurately with analytical balance, and 3 portions were used for each kind of sample. The atomic absorption spectrometry was used to determine the contents of trace elements （Cu, Zn, Fe, Cr, Ni and Mn）, and the content discrepancy of the trace elements in different medicines was observed the results shows that the contents of the trace elements were rich in the 16 kinds of Chinese herbal medicines, there were more contents of Fe, Zn and Mn, but they were different in different medicines. And there were more trace elements in Salisburia adiantifolia, Polygonum multiflorum Thunb, Bupleurum faleatum, Sehizandra sinensis Bail, Pinellia ternate Breit and Lithospermum officinalel, and lower trace elements in Radices puerarire, Rhizoma acori gramjnoi and Radices isatidis seu baphieacanthi. The analytic results provided useful data for using Chinese herbal medicines and provided theoretical basis for studying Chinese herbal medicines theory.
