Abstract
Litsea garciae is an evergreen tree growing up to 26 meters tall and useful tropical plant species. This plant have medicinal uses. The lightly burned bark can be used to cure caterpillar sting. The purpose of this study was to analyze the characteristics of secondary metabolite compounds, total phenolic and flavonoid content, antioxidant and antibacterial activity from leaf, bark and branch of L.itsea garciae plant extracts. Antioxidant activity was determined by using free radical method (1,1-diphenyl 2-picrylhydrazyl). Antibacterial activity against Propionibacterium acnes was assayed by 2,3,5-triphenyl tetrazolium chloride method. The sample extracts were obtained using a successive maceration method with n-hexane, ethyl acetate, and ethanol solvent. The result of phytochemical analysis on Litsea garciae extract positive contained several secondary metabolite compounds. Among the three sample extracts, the highest of total phenol content present in all three parts of ethanol extract with a value of 0.9-1.0 μg/mg GAE. The highest total flavonoid content was 10.1 μg/mg CE. The highest antioxidant activity was found in ethyl acetate stem extract (86% ± 0.00) at 100 ppm concentration, with IC50 at 41.54 ppm. The present work showed that L. garciae ethanol extract has potential to inhibit the growth of P. acnes bacteria.
