Simultaneous and Rapid Detection of Concentrated Liquid of Compound Dahuang Decoction Based on Near Infrared Spectroscopy
Near infrared spectroscopy was used to detect the concentration density (25 ℃)
solid-containing content
rhein content and glycyrrhizic acid content of compound Dahuang decoction.
Method:
2
The concentrated liquid of compound Dahuang decoction was determined by near infrared optical fiber transmission spectrometry. The contents of rhein and glycyrrhizic acid were determined by HPLC. Fifty-one samples were used for internal cross-validation
and partial least square regression was used to establish correction models between near-infrared spectrum and density
solid-containing content
rhein content and glycyrrhizic acid content
respectively. Ten unknown concentrated liquid samples were collected for external validation and prediction.
Result:
2
The external validation complex correlation coefficients between near-infrared spectra and density
solid-containing content
rhein content and glycyrrhizic acid content of the concentrated liquid of compound Dahuang decoction were 0.995 9
0.999 6
0.997 0 and 0.992 2
and the root mean square error of prediction (RMSEP) values were 2.50×10
-3
0.17
7.57 and 67.10
respectively.
Conclusion:
2
The near infrared spectroscopy is suitable for the determination of evaluation indexes of the concentrated liquid index of compound Dahuang decoction
