Inovasi Teh Daun Bakau Minyak (Rhizophora apiculata) dan Kandungan Kimianya

Abstract

Bakau Minyak (Rhizophora apiculata) is a species of the Rhizophoraceae family which is one of the most important species in the mangrove forest ecosystem. This study aims to analyze the content of chemical compounds in bakau minyak leaves (R. apiculata), analyze the tannin content in bakau minyak leaves (R. apiculata), analyze the antioxidant activity of bakau minyak leaves (R. apiculata), determine the level of public preference for bakau minyak tea (R. apiculata). Testing for chemical compounds in bakau minyak leaves was carried out using the phytochemical screening method which included examining the class of alkaloids, flavonoids, triterpenoids, tannins, saponins, steroids and glycosides. Determination of tannin content was carried out using the Lowenthal- Procter method. Determination of antioxidant activity was carried out using the 2,2-diphenyl-1-picrylhdrazyl (DPPH) using UV-Visible Spectrophotometry. Consumer preference level was tested by hedonic test based on color, aroma and taste parameters. The results of the phytochemical screening test for the ethanol extract of bakau minyak R. apiculata positively contain saponins, tannins, flavonoids, triterpenoids, glycosides and negatively contain alkaloids and steroids and the hot water extract of bakau minyak R. apiculata positively contains saponins, tannins, flavonoids, triterpenoids, glycosides, steroids and negatively contain alkaloids. Results of testing the analysis of tannin content in bakau minyak R. apiculata using a UV-visible spectrophotometerobtained with a value of 126.94 mg GAE/g. The results of test antioxidant activity using DPPH showed that the ethanol extract of bakau minyak leaves R. apiculata had antioxidant activity that was classified as very strong with a value of 6,990 ppm and the hot water extract of bakau minyak leaves R. apiculata had antioxidant activity that was classified as strong with a value of 58,139 ppm. Based on the hedonic test results of bakau minyak tea R. apiculata with color, aroma and taste parameters, bakau minyak tea was in adequate level.
