Simulated Accelerated Test to Study Correlation Between Color Change in Storage and Medicinal Ingredients of Rhei Radix et Rhizoma
To study the correlation between the content changes of main medicinal ingredients and the color values of Rhei Radix et Rhizoma during storage based on the principle of chromaticity analysis
and to provide reference for studying on the mechanism of discoloration and improving the quality evaluation of Rhei Radix et Rhizoma.
Method:
2
Simulated accelerated test was adopted in this study
where Rhei Radix et Rhizoma was stored under high temperature(40±5) ℃
high humidity RH(92.5±5)%and strong light(4 000±500)Lx conditions to accelerate its discoloration. For the samples taken at different time points
the color value was determined by spectrophotometer and the total contents of anthraquinone and free anthraquinones
sennoside A
B
catechin and gallic acid were determined by high performance liquid chromatography (HPLC). The correlation between the effective components and the color value of rhubarb was analyzed by SPSS software.
Result:
2
During the storage process
it was observed by the eye that the color of Rhei Radix et Rhizoma was significantly darker and darker in the simulated acceleration test. According to the analysis of the chromaticity value results
the changes of chromaticity values

and significantly positively correlated with catechin content(

but there was no correlation with total anthraquinones and sennoside A. The chromaticity value

Conclusion:
2
There is a certain correlation between the change of color value and the content of six medicinal ingredients during Rhei Radix et Rhizoma storage.
