芦荟、白芷提取物联合应用的抗氧化和美白活性评估

Evaluation of Antioxidation and Whitening Activities for Combination of Aloe vera and Angelica dahurica Extracts

为评估芦荟和白芷的乙醇提取物联合应用在抗氧化和美白方面的协同增效作用,采用乙醇浸提法从芦荟和白芷中提取分离功效成分,应用DPPH和ABTS方法评估其抗氧化活性,酪氨酸酶活性抑制实验评估其美白活性。结果表明,芦荟和白芷提取物联合应用比单独应用具有更强的抗氧化、清除DPPH自由基和抑制酪氨酸酶活性。芦荟和白芷提取物联合应用在抗氧化和美白方面具有协同增效作用。

To evaluate the synergetic effect of antioxidation and whitening activities for combination of Aloe vera and Angelica dahurica extracts,the active ingredients from Aloe vera and Angelica dahurica were separa- ted by an ethanol extraction method. The antioxidant activity was evaluated by DPPH and ABTS methods. And the whitening activity was tested by using a tyrosinase inhibition experiment. Results showed that, the combina- tion of Aloe vera and Angelica dahurica extracts had stronger antioxidant activity than the individual, as well as in the aspect of DPPH free radical scavenging and inhibiting tyrosinase activities. It has significant synergetic effect of antioxidation and whitening activities for combination of Aloe vera and Angelica dahurica extracts.
