Abstract

Mangrove species Rhizophora mucronata fruit has the potential to be utilized in a variety of processed foods. This study aimed to analyze the flavonoid compounds from the ethanol extract of fruit powder mangrove Rhizophora mucronata. The study conducted through several stages, extraction using ethanol solvent, phytochemical screening, FT-IR (Fourier Transform Infrared Spectroscopy), the creation of a standard solution and eluent preparation, isolation of flavonoids using TLC (Thin Layer Chromatography) densitometric method. The results of the analysis of phytochemical screening showed positive results containing flavonoids. Determination of Rutin at 0.32 to 0.46 Rf range obtained rutin an average grade 13.29% ± 0.43. Infrared spectrum analysis showed absorption OH phenol in number 3260 cm-1, C = C aromatic ring in the area from 1650 to 1450 cm-1, and the absorption at 1660 cm-1 indicating a carbonyl group C = O.
