| 摘 要： | 目的运用近红外光谱技术（NIR）快速测定青翘中醇浸出物的含量。方法运用NIR结合偏最4、二乘法（PLS）建立青翘药材中醇浸出物含量的定量校正模型。结果所建立的定量校正模型内部交叉验证决定系数为0．99262，内部交叉验证均方差为0．83793，校正均方差为0．284，预测均方差为0．438。结论运用NIR测定青翘药材中醇浸出物含量是可行的。

| Abstract: | Objective To determine the content of ethanol-extract in green Forsythia Fructus by near-infrared spectros- copy （NIR）. Methods The quantitative model of ethanol-extract in green Forsythia Fructus was established by combining the NIR with partial least squares. Results The correlation coefficients, root mean square error of cross validation, root mean square error of calibration and root mean square error of predication was O. 992 62,0.837 93,0.284 and O. 438 ,respectively. Conclusion It is feasible to determine the content of ethanol-extract in green Forsythia Fructus by NIR. |
