Total Phenolic and Flavonoid Content, Antioxidant, and Toxicity Test with BSLT of Meistera chinensis Fruit Fraction from Southeast Sulawesi

Meistera chinensis is one of the new generations Zingiberaceae family. have a large number species and still need research to reveal their chemical content. chinensis, local plant that widespread in Konawe Regency, Southeast Sulawesi. Empirically, M. used as flavor enhancer food, aches, increases body immunity. There are no reports content or its biological activity. In this study, fruit was tested for phytochemicals, antioxidants using ABTS test, total phenolic, flavonoid content, toxicity test with BSLT. extracted ethanol fractionated by ethyl acetate solvent use vacuum liquid chromatography. Phytochemical screening carried out qualitatively calorimetric method. The fraction monitored lethal brine shrimp (BSLT). These fractions method obtained 1-8 (F1-F8) ascorbic acid were controls. results showed radical scavenging activities very strong activity IC50 42.7±3.53 mg/L (F8). phenolic contents 30.72±1.07 mgGAE/g 8.02±0.48 mgQE/g, respectively. phytochemical evaluation contains terpenoids, saponins, phenolics, steroids, alkaloids, flavonoids. BSLT found be toxic 5.20±0.72 mg/L. findings indicate acts an antioxidant agent.
