目的 采用多指標成分定量結合化學計量學評價小兒感冒顆粒的質量。方法 采用UPLC法測定15批小兒感冒顆粒中告伊春、木犀草苷、綠原酸、3,5-O-二咖啡?；鼘幩?、對羥基苯乙酮、迷迭香酸、靛玉紅、連翹苷，結合聚類分析、主成分分析評價不同廠家、不同批次小兒感冒顆粒的質量差異。結果 15批小兒感冒顆粒樣品分為3類，同廠家樣品間差異性不明顯，不同廠家樣品存在差異性。3個主成分的累計方差貢獻率達到91.050%。結論 方法高效、科學合理，結果較準確，可用于小兒感冒顆粒質量綜合評價。

Objective To evaluate quality of Xiaoer Ganmao Granules by multi-index component determination combined with chemometrics. Methods UPLC method was used to determine contents of goitrin, luteolin, chlorogenic acid, p-hydroxyacetophenone, 3,5-O-dicaffeoylquinic acid, rosmarinic acid, forsythin, and indigo in 15 batches of Xiaoer Ganmao Granules, and cluster analysis and principal component analysis were combined to evaluate the quality differences of Xiaoer Ganmao Granules from different manufacturers and batches. Results Fifteen batches of Xiao’er Ganmao Granules were divided into three categories, and there were no obvious differences between samples from the same manufacturer, but there were differences between samples from different manufacturers. The cumulative variance contribution rate of the three principal components reached 91.050%. Conclusion The method is efficient, scientific, and reasonable, and the results are accurate, which can be used for comprehensive quality evaluation of Xiaoer Ganmao Granules.
