| 摘要： | 目的 分析黄芪闷润、蒸润切制前后的量值传递规律。方法制备3批黄芪闷润、蒸润切制饮片。通过《中药色谱指纹图谱相似度评价系统（2012版）》建立黄芪药材及其闷润、蒸润切制饮片的高效液相色谱叠加指纹图谱，结合前期定性分析结果指认共有峰，分析共有峰峰面积变化，并进行主成分分析。采用高效液相色谱法测定黄芪药材及其闷润、蒸润切制饮片中毛蕊异黄酮苷、黄芪皂苷Ⅰ、黄芪甲苷的含量，并比较不同样品中各成分的含量差异。结果指纹图谱分析结果显示，共指认了17个共有峰；黄芪闷润、蒸润后，饮片中各共有峰峰面积占比相比药材均发生了变化（如黄芪蒸润切制饮片中丙二酰基毛蕊异黄酮苷和丙二酰基黄芪皂苷Ⅰ峰面积占比降低，毛蕊异黄酮苷峰面积占比升高）。主成分分析结果显示，黄芪药材、黄芪闷润切制饮片、黄芪蒸润切制饮片各自聚为一类。含量测定结果显示，与黄芪药材相比，黄芪闷润切制饮片中毛蕊异黄酮苷的平均含量显著降低（P＜0.05）；黄芪蒸润切制饮片中毛蕊异黄酮苷、黄芪甲苷的平均含量均显著升高（P＜0.05）；黄芪闷润切制饮片中黄芪甲苷以及2种饮片中黄芪皂苷Ⅰ的平均含量差异均无统计学意义（P＞0.05）。结论黄芪药材闷润、蒸润切制前后量值传递规律存在差异，其中蒸润切制可能使不稳定成分（如丙二酰基毛蕊异黄酮苷、丙二酰基黄芪皂苷Ⅰ）转化更完全。 |
| ABSTRACT： | OBJECTIVE To analyze the quantity transfer rule in the processing of Astragalus membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. METHODS Three batches of A. membranaceus decoction pieces processed through moistening-soaking and steaming-soaking followed by cutting were prepared. The HPLC overlapping fingerprints of A. membranaceus and its decoction pieces were established through the Similarity Evaluation System of Chromatographic Fingerprints of TCM （2012 edition）. Combined with the previous qualitative analysis results， the common peaks were identified， the changes of common peak area were analyzed， and the principal component analysis was carried out. The contents of calycosin-7-glucoside， astragaloside Ⅰ and astragaloside Ⅳ in A. membranaceus and its decoction pieces were determined by HPLC， and the content differences of each component in different samples were compared. RESULTS The results of fingerprint analysis showed that 17 common peaks were identified. After steaming-soaking and moistening-soaking of A. membranaceus， the proportion of common peak area in the decoction pieces changed compared with the original medicine （for example， in A. membranaceus steaming-soaking decoction pieces， the proportion of peak area of malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ decreased， while the proportion of peak area of calycosin-7-glucoside increased）. The results of principal component analysis showed that A. membranaceus， and its decoction pieces after moistening-soaking and steaming-soaking followed by cutting were all clustered into one category respectively. The results of content determination showed that， compared with A. membranaceus， the average content of calycosin-7-glucoside in A. membranaceus moistening-soaking decoction pieces was significantly reduced （P＜0.05）； the average contents of calycosin-7-glucoside and astragaloside Ⅳ in A. membranaceus steaming- soaking decoction pieces were significantly increased （P＜0.05）； there was no significant difference in the average content of astragaloside Ⅳ in A. membranaceus moistening-soaking decoction pieces and astragaloside Ⅰ in the two decoction pieces （P＞ 0.05）. CONCLUSIONS There are differences in the quantity transfer rules of A. membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. Steaming-soaking followed by cutting may make the transformation of unstable components （such as malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ） more complete. |
