| 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. |
