| 摘 要： | 采用红外指纹图谱结合计算机辅助比对软件技术,对14个省32个牛膝样品进行了道地与非道地性的鉴别研究,并对部分不同贮存时间的牛膝进行了对比,以考察其在贮存过程中的变化情况.结果表明,各产地牛膝的相关系数有一定的差异.以0.9840为划分标准,相关系数大于0.9840的为道地牛膝药材(怀牛膝),小于0.9840的为非道地牛膝药材;通过不同贮存时间牛膝相关系数的变化,可以考察牛膝在贮存过程中是否发生变化及变化大小.本方法制样简单、测定快速、结果可靠、重复性好.

| Abstract: | Objective: To study the genuine of 32 samples of Niuxi from 14 provinces, and compare some samples stored for different time to check the change in the coures of store Method: IR spectroscopy and Analyze Technology Auxiliary softeare Result: The coefficient correlations had certain difference among these Niuxi from different places They were divided into two parts if r=0 9840 the standerd: trueborn crude drugs(r>0 9840) and non trueborn(r<0 9840) And we can know the change in medicinal materials according r Conclusion: The method is operated simple and determined fast; the result is reliable; repetitiveness is good |
