玄明粉炮制方法考证及其拉曼光谱研究

Researches on the Processing Methods and Raman Spectroscopy of Matrii Sultas Exsiccatus

目的:通过本草考证和现代实验研究,以期明确玄明粉炮制方法变革原因。方法:通过对古代本草和现代炮制规范的考证,了解各时期玄明粉炮制方法的差异,依据本草中不同炮制方法制备玄明粉,利用拉曼光谱技术对其进行分析。结果:通过考证发现古代本草中玄明粉炮制方法存在明显区别,而在现代炮制规范中两者炮制方法趋于一致,依据古籍制备的玄明粉与风化硝样品拉曼光谱无明显差异,两者拉曼特征峰均为:1 153,1 132,1 102,992,648,632,621,466,450 cm^(-1),与现代炮制方法也相符合。结论:古代玄明粉炮制方法变革到现代方法具有一定道理,但仍需进一步研究。

Objective： To find out the transformation reasons of the processing methods for Matrii sultas Exsiccatus through the bencaological study and the modem experimental researches. Methods： The different processing methods for Matrii sultas Exsiccatus in different periods were collected through the researches on the ancient agrostology and the modem processing standards. Furthermore, different processed products were prepared and analyzed by Raman spectroscopy. Results： There were significant differences in the processing methods for Matrii sultas Exsiccatus in the ancient herbal documents while tending to be the same in the modem processing standards. No difference was shown in the Raman spectrogram between Matrii sultas Exsiccatus and Weathered mirabilite produced by the processing methods in the ancient agrostology. The Raman characteristic peaks of the two processed products were as follows： 1 153, 1 132, 1 102,992,648,632,621,466,450 cm^-1, which were in line with the Raman spectrogram of the products produced by the modem processing methods. Conclusion： The change of processing methods for Matrii sultas Exsiccatus has certain reasons, which is worthy of further studies.
