TITLE: | |
摘要: | 目的:建立石仙桃药材的高效液相色谱(HPLC)指纹图谱并进行聚类分析,为石仙桃药材的质量评价提供参考。方法:根据《中药色谱指纹图谱相似度评价系统》(2012版)建立广西、广东和福建产16批石仙桃药材的HPLC指纹图谱[色谱柱为Agilent SB-aq,流动相为乙腈-0.05%磷酸水溶液(梯度洗脱),流速为1.0 mL/min,检测波长为220 nm,柱温为30 ℃,进样量为5 μL],并采用SPSS 22.0统计学软件对其进行聚类分析。结果:根据建立的HPLC指纹图谱,共确定了11个共有峰,并指认了其中的共有色谱峰1为天麻素;16批样品的相似度均大于0.9。16批药材样品可聚为2类。结论:建立的HPLC指纹图谱和聚类分析结果可为石仙桃药材的质量控制提供一定的参考。 |
ABSTRACT: | OBJECTIVE: To establish HPLC fingerprint of Pholidota chinensis and cluster analysis the samples, and to provide reference for quality evaluation of P. chinensis. METHODS: HPLC fingerprints of 16 batches of P. chinensis from Guangxi, Guangdong and Fujian were established according to 2012 edition of Similarity Evaluation System for Chromatographic Fingerprint of TCM [chromatographic column was Agilent SB-aq column with mobile phase consisted of acetonitrile-0.05% phosphoric acid solution (gradient elution), at the flow rate of 1.0 mL/min. The detection wavelength of 220 nm, the column temperature was 30 ℃ and the sample volume was 5 μL].The cluster analysis was carried out by using SPSS 22.0 statistical software. RESULTS: Accoding to the established HPLC fingerprint, 11 common peaks were indentified, and the common peak 1 was identified as gastrodin; the similarity of 16 batch of samples was greater than 0.9. 16 batches of medicinal materials could be divided into 2 groups. CONCLUSIONS: The established HPLC fingerprint and cluster analysis can provide reference for the quality control of P. chinensis. |
