A Comparative Study on Antioxidant and Anti-inflammatory Effects of Green Coffea arabica Beans by Country of Origin

In this study, the extracts of green Coffea arabica bean by country of origin were tested as a potential source for natural ingredients in cosmetic products. Antioxidative activities were measured by total polyphenol, 1,1-diphenyl-2-picrylhydrazyl radical (DPPH), and 2,2 -azino-bis (3- ethylbenzothiazoline-6-sulphonic acid) (ABTS) assay. Anti-inflammatory activities were checked by nitric oxide (NO) assay. The total polyphenol content was found to be higher in ethanol extract than in water extracts, and in particular Ethiopia ethanol extracts had 852.39 mg/100 g, making them the highest in content. The antioxidant measurement was measured with DPPH and ABTS, indicating that antioxidant strength increased dependent on the concentration of all extracts to be superior. The cell survival rate of the extracts of green Coffea arabica beans by country of origin was confirmed by MTT assay and was close to 100 ㎍/㎖ to 100%. Anti-inflammatory activity by NO assay showed lipopolysacchride (LPS)-induced NO was significantly inhibited following treatment with extract of green Coffea arabica beans by country of origin and decreased in a concentration-dependent manner. This study confirmed the efficacy of green Coffea arabica beans by country of origin through research related to antioxidants and anti-inflammatory, and confirmed its availability as a natural material for cosmetics.
