Presented by: Miin Chiu
Introduction
In recent years, consumers choose skincare cosmetics, brand's claim is no longer sole basis in judgement, more and more consumers will pay attention to whether the ingredients in beauty products are natural, safe and effective, which also gives natural, healthy Chinese herbal medicine (CHM) great room for development. The development of Chinese herbal medicine has a history of thousands of years, how to find out safe and effective raw materials of Chinese herbal medicine is the purpose of this study. Four nourishing CHMs (Prunella vulgaris, Pv、 Cuscuta chinensis, Cc、 Magnolia officinalis, Mo and Davallia formosana Hayata, DfH) were selected as study materials to estimate the bioactivities by antioxidant ability and antioxidant content assay.
Methods
The methods of bioactivity analysis were divided into two parts, one is antioxidant activity assessments (including DPPH radical-scavenging activity assay and ferric reducing antioxidant power, FRAP assay), the other is antioxidant content determinations (containing total phenolic content and total flavonoid content).
Results
Results showed that the DPPH free radical scavenging ability of four CHMs in both water extracts and ethanol extracts were better than Vitamin C, the extracts of Cuscuta chinensis were excellent than BHA. The reducing power of all CHMs water extracts were little less than Vitamin C. The total phenolic content of four CHMs were not enough, but total flavonoid contents of Magnolia officinalis extracts were quite high that lead to the strong reducing ability.
Conclusion
In addition to the tonic effect for four Chinese herbal medicines selected, all the extracts of them have good free radical scavenging capacity, the ethanol extract is much better than the water extract. Magnolia officinalis will have the priority to be selected as the best raw material to add into skincare products because of its strong antioxidative ability and high total flavonoid content.
