| Popis: | The exposure of reactive oxygen species is one of the aging triggers at cellular level. The antioxidants have been used as strategic efforts in overcoming the accumulation of ROS. Previous research using crude extracts of clove bud and leaves showed its potential as an antioxidant agent. However, no data were available regarding the antioxidant and antiaging activities of subsequent fractions of clove extracts. Therefore, this study aimed to analyze the antioxidant and antiaging activities of the n-hexane and ethanol fractions from clove bud and leaves. Antioxidant and antiaging activities were tested at the cellular level using the yeast model Schizosaccharomyces pombe. The highest flavonoid content was shown by clove leaf n-hexane fraction (25.6 mgQE·g−1). However, ethanol fraction of clove bud (FEB) showed the highest antioxidant activity based on TBA and antiglycation assays. FEB (8 μg·mL−1) and leaf ethanol fraction (FEL) (10 μg·mL−1) were able to induce yeast tolerance against oxidative stress. In addition, FEB could induce mitochondrial activity and delay the G1 phase of the cell cycle. FEB was found to be rich in gallic acid and (15Z)-9,12,13-trihydroxy-15-octadecenoic. Based on the data, FEB shows the potential antiaging activity, which is promising for further development as biopharmaceutical product formulations. |
