Aurea helianthus (AH), one of representative warm-temperature plant in southern Korea, is traditionally used in China for various medicinal purposes. The bioactive constituents from aerial parts of the AH leaf and stem as well as flowers have been studied by several researchers showing anti-inflammation, immune-modulatory, antioxidant, and whitening effects. However, the effects of the AH flower on the biological activities for cosmetic application have not been thoroughly investigated. This study reported the possible utilization of AH flower extracts (AHF) with different extraction methods and validated antioxidant and analysis of the bioactive components. The AHF was treated with hot water, cold water, 70% ethanol respectively. Besides component analysis of the extract, the antioxidant activities were determined with 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging and 2,2"-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assay. The 70% ethanol extracts showed the highest antioxidant activities and active ingredient contents like the total phenolic, flavonoid and sugar and protein contents. Interestingly, collagen contents and free amino acids analysis were determined maximum in the cold-water extracts. Then the diversification and standardization of extraction methods were to be studied further in the future. In summary, AHF are useful plant resources that can provides promising antioxidation and can be used as potential natural cosmetics ingredients and healthy foods.
