		abstract={Red kidney bean is one of the string bean that contain highest fiber with
concentration 26,3 gram/100 gram substance. Red kidney bean contains flavonoid
tannin steroid/triterpenoid and kumarin. Flavonoid in red kidney bean has antidiabetes activity. This research aims to determine total flavonoids content in the red
kidney bean extract. Extraction is done using maceration method with 70% ethanol
solvent. The extract which is got is used for qualitative and quantitative analysis.
Quercetin used as a standard solution. Qualitative analisys using TLC, Wilstater
Cyanidin method, and qualitative analisys using aqueous NaOH. Quantitative
analysis using Visible Spectrophotometry on a wavelength of 430.0 nm and
operating time at the 27th minute. The results of qualitative test showed that the
extract was positive flavonoids. The average concentrations of total flavonoids was
0,4733% extract with a variation coefficient value of 1,2%.}
