摘要

目的: 运用近红外光谱法快速测定青翘中连翘苷、连翘酯苷A及醇浸出物的含量。方法: 运用近红外光谱技术结合偏最小二乘法（PLS）建立青翘中连翘苷、连翘酯苷A及醇浸出物含量的定量校正模型。结果: 连翘苷、连翘酯苷A及醇浸出物的定量校正模型的内部交叉验证决定系数（R2）分别为0.957 33，0.986 93，0.992 62，验正集相关系数（r）分别为0.941 9， 0.976 1，0.989 7。结论: 近红外光谱法简便准确，可用于青翘中连翘苷、连翘酯苷A及醇浸出物含量的快速测定。

Abstract

Objective: To determine the content of phillyrin

forsythoside A and ethanol-extract in green Forsythiae Fructus by near-infrared spectroscopy. Method: Combine the near-infrared spectroscopy with partial least squares (PLS) to establish the quantitative model of phillyrin

forsythoside A and ethanol-extract in grown Forsythiae Fructus. Result: The correlation coefficients (R2) of phillyrin

forsythoside A and ethanol-extract were respectively 0.957 33

0.986 93 and 0.992 62.The validation coefficients (r) were respectively 0.941 9

0.976 1 and 0.989 7. Conclusion: The method is convenient and accurate and it's feasible to determine the content of phillyrin

forsythoside A and ethanol-extract in green Forsythiae Fructus by near-infrared spectroscopy.
