Abstract:
OBJECTIVE To study the correlation between processing time, chroma value and UPLC fingerprint map of Dipsaci Radix. METHODS Established the UPLC fingerprint of Dipsaci Radix. Monitored the changes of chemical components in the processing process of wine and salt processed Dipsaci Radix, spectrophotometer was used to objectively quantify the chroma value of different processed products. SPSS 20.0 and SIMCA 14.0 statistical software was used to analyze the correlation between processing time and chroma value and fingerprint. RESULTS In the process of processing, the decoction pieces color of the powder deepened and L*, b* and E* values decreased. The correlation analysis showed that the processing time was significantly correlated with the chroma value and fingerprint of decoction pieces. CONCLUSION The method of UPLC fingerprint is stabled and reliabled, combines with the objective discriminant analysis of the chroma value of the Dipsaci Radix processed products, which lay the foundation for standardizing the processing technology of wine and salt processed products and evaluating the quality of Dipsaci Radix.
