Comparison of antioxidant activity of two Chinese herbal cosmetic formulations
The antioxidant activities of two cosmetic formulations with different effects composed of a variety of Chinese herbal extracts were compared,such as the content of phenol and total flavonoids,the scavenging ability of DPPH free radical and the reducing ability.The contents of total phenolic flavonoids in whitening formula are 720.25 mg GAE/g and 18.17 mg QE/g respectively,the contents of total phenolic flavonoids in moisturizing formula are 538.88 mg GAE/g and 4.34 mg QE/g respectively,and the EC50 values of whitening formula and moisturizing formula are 106.44 μg/mL、98.27 μg/mL,the experimental results show that the content of total phenol and total flavonoids in whitening formula is greater than that in moisturizing formula,the EC5o of whitening formula is less than that of moisturizing formula,and the reduction ability of whitening formula is greater than that of moisturizing formula.Through the comparison of these indexes,it can be seen that the antioxidant capacity of whitening formula is stronger than that of moisturizing formula.The experiment also used whitening and moisturizing herbal formulations as raw materials,which were incorporated into the preparation process of lotion and emulsion,respectively,to prepare well performing lotions and emulsions with whitening and moisturizing effects.
