Rapid Determination of Moisture Content in Amomi Fructus by Near Infrared Spectroscopy
Objective: To quickly determine the moisture content in Amomi Fructus by using near infrared spectroscopy(NIRS) technology. Method: Vacuum drying method was used for determination of moisture content in samples of Amomi Fructus.Both standard normalization method and the second derivative method were used for the spectra pretreatment
combined with partial least squares(PLS) to establish near infrared quantitative analysis models for the moisture content of Amomi Fructus. Result: The internal cross-validation correlation coefficient (R2) in the calibration set of the established models
root mean square error of calibration (RMSEC)
root mean square error of prediction (RMSEP) and the performance index (PI) were 0.986 7
0.242
0.285 and 92.5. Conclusion: The method is simple
rapid
accurate
and non-destructive
and can be used for rapid determination of moisture content in Amomi Fructus.
