Abstract

Cinnamon bark contains compounds that can be used as traditional medicine. The content of compounds in cinnamon bark are flavonoids, saponins, tannins, alkaloids, eugenols, and cinnamaldehydes. One of the contents of cinnamon bark compound is flavonoids which have antioxidant activity. The purpose of this study was to determine the antioxidant activity content in cinnamon bark ethanol extract from maceration and socletation extraction methods using UV-Vis spectrophotometry. The method of extracting compounds in this study uses maceration and sokhletation extraction methods, while for testing the antioxidant activity in this study using the FRAP method. The results of the search by comparing the two extraction methods obtained better yields on the maceration method with a yield of 70.2%. Antioxidant activity test using FRAP method found antioxidant activity on cinnamon bark extraction method that is 0.24880 mgAAE / g extract with %KV that is 0.06%. Whereas the extraction of cinnamon bark soccletation on a 50µl pipeline had a smaller antioxidant activity of 0.09678 mgAAE / g extract with an average %KV of 0.11%. Comparison test with ANOVA analysis obtained sig. <0.05 ie there is a significant comparison between antioxidant activity between maceration and socletation extraction methods.
