摘要: | 目的 比较姜半夏与其竹沥炮制品的高效液相色谱(HPLC)指纹图谱及核苷类成分变化,为竹沥半夏的质量评价提供参考。方法采用《中药色谱指纹图谱相似度评价系统(2012版)》建立10批姜半夏及其炮制品竹沥半夏的HPLC指纹图谱,并对其共有峰进行系统聚类分析(HCA)、主成分分析(PCA)和正交偏最小二乘-判别分析(OPLS-DA);测定姜半夏与竹沥半夏中次黄嘌呤、尿苷、腺嘌呤、鸟苷共4种核苷类成分的含量。结果10批姜半夏和竹沥半夏与其对应对照指纹图谱R的相似度均在0.851~0.990之间。2种样品共得到10个共有峰,并指认出了4个成分,分别为次黄嘌呤、尿苷、腺嘌呤、鸟苷。HCA、PCA、OPLS-DA结果均显示,姜半夏、竹沥半夏样品分别聚为一类,且OPLS-DA筛选出姜半夏与竹沥半夏4个差异性成分,根据变量重要性投影值排序依次为峰8、峰1、峰6(腺嘌呤)、峰10。含量测定结果显示,竹沥半夏中次黄嘌呤、尿苷、腺嘌呤、鸟苷的平均含量较姜半夏分别下降了15.90%、12.00%、26.04%、22.18%,其中次黄嘌呤、腺嘌呤、鸟苷含量差异具有统计学意义(P<0.05或P<0.01)。结论本研究建立的指纹图谱及含量测定方法操作简便、重复性好,可用于姜半夏和竹沥半夏的定性、定量分析;竹沥炮制姜半夏后4种核苷类成分的平均含量降低。 |
ABSTRACT: | OBJECTIVE To investigate the changes in high performance liquid chromatography (HPLC) fingerprint spectra and nucleoside components between Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and its processed product Succus bambusae pinella preparata, providing a reference for the quality evaluation of the latter. METHODS HPLC fingerprint was established for 10 batches of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and its processed product Succus bambusae pinella preparata following the Similarity Evaluation System of TCM Chromatographic Fingerprints (2012 Edition). Hierarchical cluster analysis (HCA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS- DA) were conducted on their common peaks. The contents of four nucleoside components, hypoxanthine, uridine, adenine, and guanosine, in both Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata were determined. RESULTS The similarity between the fingerprints of the 10 batches of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, Succus bambusae pinella preparata, and their corresponding reference fingerprints ranged from 0.851 to 0.990. A total of 10 common peaks were obtained for both samples, and 4 components were identified as hypoxanthine, uridine, adenine, and guanosine. The results of HCA, PCA and OPLS-DA showed that the samples of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata were clustered into separate categories, with OPLS-DA selecting 4 differential components between them, ranked by variable importance projection values as peak 8, peak 1, peak 6 (adenine) and peak 10. The content determination results showed that the average contents of hypoxanthine, uridine, adenine and guanosine in Succus bambusae pinella preparata declined by 15.90%, 12.00%, 26.04% and 22.18% compared to Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, respectively, with statistically significant differences in the contents of hypoxanthine, adenine and guanosine (P<0.05 or P<0.01). CONCLUSIONS The established fingerprint and content determination methods are simple to operate and have good repeatability, which are suitable for qualitative and quantitative analysis of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata. The average contents of the four nucleoside components decreased after the processing of Succus bambusae pinella preparata. |
