Abstract

The purpose of this research was to observe the content of phytochemical component and antioxidant activity of chinese water chesnut purun extract (Eleocharis dulcis) and giant molesta (Salvinia molesta) with three solvents of different levels of polarity. This research was conducted in December 2017 until October 2018. This study used an experimental laboratory method and data analysis was carried out descriptively. Some of the steps carried out include the stages of sampling, sample extraction, calculation of extract extracts, quantitative phytochemical analysis (flavonoid content, phenol content, phenolic content, and tannin content), and test phase of antioxidant activity (DPPH, ABTS and Reducing ability) The results showed that extracts of extract using ethanol 70% in chinese water chesnut (Eleocharis dulcis) and giant molesta (Salvinia molesta) had the highest values of 2.01% and 2.26%. Quantitative phytochemical tests on chinese water chesnut extract and giant molsta showed that ethanol 70% solvents at flavonoid levels had the highest values of 288.75 mg/ml and 267 mg/ml. The results of antioxidant activity with the chinese water chesnut and giant molesta extracts had very weak IC50 values in n-hexan solvents valued at 1977.22 ppm and 3211.2 ppm. Chinese water chesnut of extract had the highest ABTS value in ethyl acetate solvents at a concentration of 1000 ppm at 85.253% and in giant molesta extract at a concentration of 1000 ppm using ethanol 70% solvent had the highest value of 76.665%. Ethanol 70% extract in chinese water chesnut extract and giant molesta had the highest reducing ability power with a mean absorbance of 0.477 and 0.520. The best solvent for extracting rat purun and kiambang is 70% ethanol.
