Abstract

The amount of solvent affects the effectiveness of the extraction, so the chemical components are extracted entirely from the plant. This study investigated the best ratio of Akway bark : solvent (ethanol) to produce Akway extract with the highest antioxidant activity. Extraction with the treatment of Akway skin: ethanol ratio of 1:2; 1:4; 1:6 (b/v) was carried out and then the results were tested for total phenolic and flavonoid content and antioxidant activity. The best Akway bark:ethanol ratio was obtained at 1:4 (b/v) ratio with 9.54% extract yield, 289.57 mg GAE/g total phenolic content, 185.47 mg eq quercetin/g total flavonoids. Akway bark extract has potential as a source of antioxidants as indicated by its high antioxidant activity with DPPH free radical scavenging and ferric reducing activity of 50% (IC50) at extract concentrations of 16.59 µg/mL extract and 60.93 µg/mL extract, and carotene bleaching inhibition activity of 85.76%. There are 4 types of phenolic compounds and 4 types of flavonoid compounds identified with the highest percentage of components, namely Pereniporin B (57%).
