摘要
目的:对野生和栽培生地黄及不同贮藏年限的生地黄(2000、2002年采收)以及“道地(河南)和非道地(其他省份)”生地黄药材进行快速鉴别研究。方法:利用傅里叶红外光谱技术(FT -IR)结合对比软件,并借助计算机运用归一化图谱辅助处理技术。结果:野生和栽培生地黄红外吸收光谱有明显的差异;对不同贮藏年限生地黄的识别率为100%;“道地和非道地”生地黄既有整体差异,又有个体交叉,识别率高于90%。结论:该方法具有快速、准确等特点。
Objective:To identify the categories of Radix Rehmannia between the wild and the planting, different stored time,(gained in 2000,2002), trueborn place (Henan) and no-trueborn places.Methods:FTIR combined compare software,and the data was dealt with the means of normalization in computer.Result:The wild and the planting have evident difference. They can be identified for the different stored-time completely. The identification percentage between trueborn place and no-truedborn places is more than 90%.Conclusion:The method is fast,accurate.
