采用高效液相色谱法获取12批补阳还五汤全方、14批补阳还五汤精简方指纹图谱化学成分的数据,运用主成分分析法（principal component analysis,PCA）对采集的数据进行降维处理,计算出综合排名第一的中药材指纹图谱批次。运用灰色关联度法（grey relational analysis,GRA）将所求批次的指纹图谱特征峰和脑损伤的保护作用关联起来,探讨补阳还五汤全方及精简方中指纹图谱共有峰和特有峰与脑损伤保护作用贡献程度的强弱关系。本研究结合PCA和GRA开展补阳还五汤谱效关系研究,能提升数据的有效性和准确度。

The HPLC fingerprint of the 12 batches of Buyang Huanwu Decoction and the 14 batches of its optimized prescriptions were determined. The principal component analysis (PCA) was used to reduce the data dimension. The ranked first batch of fingerprints of Chinese medicines were evaluated. The protective effects of brain damage and the characteristic peaks were correlated by grey relational analysis (GRA). The correlation between common peaks and charactersistic peaks of Buyang Huanwu Decoction and its optimized prescriptions with its contribution onthe protective effect of cebebral ischemia were ...
