Abstract

Indonesia is a country rich in natural resources from flora, fauna, and minerals. Many plants have medicinal properties including Binahong leaves. Binahong consists of secondary metabolites such as saponins, quinones, flavonoids, steroids, monoterpenoids, while the rhizome contains flavonoids, polyphenols, tannins, and steroids. The plant has an anti-bacterial, anti-cholesterol, healing of cuts and hepatoprotective wounds activity.  The purpose of this study is to identify the comparative content of polyphenols, flavonoids, and the antioxidant activity of binahong simplicia leaves using the oven drying method and room temperature. Observed parameters consisted of yield, water content, polyphenol content, total flavonoid levels, and antioxidant activity. Results showed that the best treatment based on the highest levels of polyphenols (1.782% vs 1.561%), flavonoids (0.702% vs  0.354%) and antioxidant activity (782.79 vs 887.31). Conclusion, the treatment of binahong leaves by oven drying produces the highest content of polyphenols and flavonoids in binahong leaves. They have antioxidant activity better than those which are produced by room temperature drying treatment
