[Effects of processing on antioxidation of Radix et Rhizoma Rhei and Rhizoma Polygoni Cuspidati]
1Nanjing University, School of Life Sciences, State Key Laboratory of Pharmaceutial Biotechnology, Nanjing 210093, Jiangsu, China.
Objective:
To investigate the effects of Processing on antioxidation of Radix et Rhizoma Rhei and Rhizoma Polygoni Cuspidati.
Method:
The oxygen free radicals generation system and mouse liver homogenate lipid peroxidation in vitro were used.
Result:
The processed products of Radix et Rhizoma Rhei and Rhizoma Polygoni Cuspidati could scavenge superoxide radical (O2-.) generated through hypoxanthine-oxidase system and (.OH) generated through Fenton action, and inhibit lipid peroxidation induced by hydroxyl radical generation system, respectively. There existed significant differences among the different processed products.
Conclusion:
After Radix et Rhizoma Rhei and Rhizoma Polygoni Cuspidati were processed, their effects became weaker.
