Abstract

Angsana (Pterocarpus indicus Willd.) is a forest plant widely used as an ornamental garden and as a shade. In many countries, Angsana is used as a traditional medicine, such as an antidiabetic drug. The compounds that act as antidiabetes are flavonoids. The purpose of this study was to determine the total flavonoid content of ethanol extract of old and young Angsana leaves using visible spectrophotometry. The wilstater test was performed as a qualitative research test to show that the ethanol extract of Angsana leaves contains flavonoid compounds. AlCl3 was selected as a reagent in visible spectrophotometry to determine the flavonoid of Angsana leaf. The result of the accuracy test was 83.67% with acceptance criterion 80-120% and the precision test is 8.96% with acceptance criterion ≤10%. The total flavonoid levels of ethanol extract of old and young Angsana leaves were respectively 7.53 ± 0.32% w/w and 3.31 ± 0.07 % w/w.
