Antioxidant Potential of Ethanol Extract of the Tarantan Plant (Tournefortia pubescens Hook. F.) by Using the DPPH Method

Abstract

This research was carried out with the aim of knowing the antioxidant activity of Tarantan (Tournefortia pubescens. Hook.f.) using the DPPH method. Tarantan is an endemic plant that is found in Bonelemo Village, West Bajo District, Luwu Regency, South Sulawesi Province and is used by the local community as a wound medicine. The research implementation method starts from taking and preparing samples, maceration using ethanol, phytochemical testing, flavonoid content testing, antioxidant testing and data analysis. Based on the results of research conducted, Tarantan (Tournefortia pubescens. Hook.f.) contains flavonoids, alkaloids, terpenoids, steroids and phenolics; The total flavonoid compound content of Tarantan (Tournefortia pubescens. Hook.f.) extract was 5.904 mg/g QE or 0.0005904%; The IC50 value of Tarantan (Tournefortia pubescens. Hook.f.) extract was 79.334 µg/mL. This value indicates that Tarantan extract (Tournefortia pubescens. Hook.f.) is a very strong antioxidant.
