Quantitative Analysis of Radix Rehmanniae from Genuine Producing Area by Near Infrared Spectroscopy

Article Preview

Abstract:

In this paper the water extract of Radix Rehmanniae from genuine producing area was rapidly determined by near-infrared spectroscopy (NIRS). The quantitative analysis model of the water extraction of Radix Rehmanniae was established by Partial Least Square (PLS). The correlation coefficient of calibration (R2) was 0.99529; the root-mean-square error of prediction (RMSEP) was 0.134. The results indicated that the water-soluble components in Radix Rehmanniae from genuine producing area can be rapidly and accurately determined by near-infrared spectroscopy technology.
