不同商品等级远志药材的HPLC指纹图谱分析

目的:对不同商品等级的远志药材进行HPLC指纹图谱分析。方法:收集河北安国、安徽亳州、广西玉林、四川荷花池4个药材市场中不同商品等级的47批远志药材,测定其直径及抽心率,构建上述药材的HPLC指纹图谱并进行相似度分析,建立不同等级远志药材的对照指纹图谱,流动相乙腈-0. 05%磷酸水溶液梯度洗脱,检测波长316 nm。结果:不同商品等级的远志药材,在化学成分的种类上相似,但在化学成分的含量上存在一定差异,远志筒统货与依据47批药材建立的对照指纹图谱的相似度介于0. 925~0. 996;远志小筒药材与对照指纹图谱相似度介于0. 840~0. 997;远志中筒药材与对照指纹图谱相似度介于0. 865~0. 996;远志大筒药材与对照指纹图谱相似度介于0. 931~0. 993。结论:传统判别药材质量优劣的"辨状论质"经验具有一定的科学依据,但后续应建立药材外观性状与其内在化学成分相关的商品等级标准,以确保同等级商品远志药材质量的一致性,进而提高其临床用药的准确性。

HPLC Fingerprint Analysis of Polygalae Radix with Different Commercial Grades

Objective: To analyze the difference of HPLC fingerprint of Polygalae Radix with different commercial grades. Method: A total of 47 batches of Polygalae Radix with different commercial grades collected from four medicinal materials markets were measured for their diameters and doping percents.The fingerprint of Polygalae Radix were analyzed by HPLC and their similarities were calculated.Then,the control fingerprint of Polygalae Radix with different grades was established. Result: The similarity between the different batches of Tonghuo and the established control fingerprint of 47 batches of Polygalae Radix ranged from 0.925 to 0.996;the similarity between the different batches of Xiaotong and the control fingerprint ranged from 0.840 to 0.997;the similarity between the different batches of Zhongtong and control fingerprint ranged from 0.865 to 0.996;the similarity between the different batches of Datong and the control fingerprint ranged from 0.931 to 0.993. Conclusion: The traditional theory of''determination of quality through characters'' experience has certain scientific basis.It is necessary to establish the standard of commercial grade related to intrinsic chemical composition and appearance for ensuring the consistency of the quality of Polygalae Radix with the same grade,and improving the accuracy of clinical use of Polygalae Radix.
