Abstract

The papaya plant is one of the plants of the Caricaceae family which is spread in the tropics, including Indonesia. Papaya leaves and flowers contain flavonoids which can be used as raw material for traditional medicines for the treatment of diabetes mellitus. The aim of the researchers was to determine the ratio of total flavonoid levels in papaya leaf and flower extract (Carica papaya L.) by UV-Vis Spectrophotometry. The method used in the research is Chang's method. Identification of flavonoids with concentrated HCl reagent and magnesium metal gives rise to a red color change indicating a positive sample containing flavonoids. The results of the study were the comparison of total flavonoid levels contained in papaya leaf and flower extract with an average flavonoid level of 6.8357% b / b for papaya leaves and 1.6025% b / b for papaya flowers. The results of the Independent Samples Test showed that there were significant differences between the levels of total flavonoid ethanol extract of papaya leaves and flowers indicated by the value of Sig. (2-tailed) 0,000 < 0,05.
