Abstract

Background Rhizome kecombrang (Etlingera elatior (Jack) R.M.Sm), is one of many plants that are in use in Indonesia. Kecombrang rhizomes (Etlingera elatior (Jack) RMSm) rich in gallic acid which is traditionally used as an antiseptic. This study aims to determine the content of gallic acid in rhizome extract kecombrang (Etlingera elatior (Jack) RMSm). Methodology Kecombrang rhizome extract (Etlingera elatior (Jack) R.M.Sm), obtained by maceration method. Analysis of the chemical components using Thin Layer Chromatography (TLC) is characterized by the appearance of stains. Assay of gallic acid kecombrang rhizome extract (Etlingera elatior (Jack) R.M.Sm), using the TLC-densitometry. Results The results showed that phytochemicals in the extract testing kecombrang (Etlingera elatior (Jack) R.M.Sm), positive for gallic acid compounds containing gallic acid is 2,00012003 mgRE/g. Discussion This research used kecombrang rhizome as a sample and extract was obtained by using maceration. Qualitative and quantitative analysis by using TLC densitometry and acid gallic p.a was used as a standard. The qualitative assay according to the Rf value that compared with standard. Quantitative measurements analyzed the data by using the calibration curve. Conclusion Rhizome kecombrang (Etlingera elatior (Jack) R.M.Sm) contains gallic acid about 2,00012003 mgRE/g.
