    摘要:

    目的 基于指纹图谱、聚类分析与主成分分析方法为不同产地荆芥药材质量控制提供参考。方法 利用高效液相色谱法对荆芥药材进行质量分析,所获数据用中药色谱指纹图谱相似度评价系统构建荆芥药材的指纹图谱,并应用SPSS 23.0统计软件进行聚类分析和主成分分析,综合评价不同产地荆芥药材的质量。色谱柱为 SinoChrom ODS -BP(4.6 mm×250 mm,5 μm);流动相为乙腈-0.05%磷酸水溶液,梯度洗脱;检测波长:283 nm;流速:1.0 mL/min;柱温:30 ℃;进样量:20 μL。结果 荆芥药材高效液相色谱指纹图谱28个峰确定为共有峰,除河南鹿邑、四川自贡的样品相似度低于0.9外,其他的21批荆芥药材的相似度为0.930~0.982。聚类分析结果表明,荆芥药材可被分为亳州荆芥与四川、河南、河北等其他产地荆芥两大类。主成分分析结果表明,前6个主成分的累计贡献率达到88.247%,选择这6个因子可对不同产地荆芥药材进行综合分析。结论 根据最终的综合得分结果可知,安徽、河北产荆芥药材质量相对较好。

    Abstract:

    Objective To provide a reference for quality control of fineleaf Schizonepeta herb from different producing areas based on fingerprint, cluster analysis, and principal component analysis. Methods High-performance liquid chromatography (HPLC) was used to analyze the quality of fineleaf Schizonepeta herb, and the data obtained were analyzed by the chromatographic fingerprint similarity evaluation system of traditional Chinese medicine to establish the fingerprint of fineleaf Schizonepeta herb. SPSS 23.0 was used for cluster analysis and principal component analysis, and all data were used to evaluate the quality of fineleaf Schizonepeta herb from different producing areas. HPLC was performed on a SinoChrom ODS-BP column (4.6 mm × 250 mm, 5 μm) with a mobile phase of acetonitrile-0.05% aqueous phosphoric acid solution for gradient elution, at a detection wavelength of 283 nm, a flow rate of 1.0 mL/min, a column temperature of 30 ℃, and an injection volume of 20 μL. Results A total of 28 peaks of the HPLC fingerprint of fineleaf Schizonepeta herb were determined to be common peaks, and apart from the samples from Henan Luyi and Sichuan Zigong with a similarity of below 0.9, all the other 21 batches had a similarity of 0.930-0.982. The cluster analysis showed that the medicinal material of fineleaf Schizonepeta herb was classified into Bozhou fineleaf Schizonepeta herb and fineleaf Schizonepeta herb from other producing areas including Sichuan, Henan, and Hebei. The principal component analysis showed that the top six principal components had a cumulative contribution rate of 88.247% and could be used for the comprehensive analysis of fineleaf Schizonepeta herb from different producing areas. Conclusion The comprehensive analysis shows that fineleaf Schizonepeta herb from Anhui and Hebei has relatively good quality.
