Abstract :
Pineapple is a fruit that is often consumed by the public. Pineapple contains flavonoid composition. Pineapple has hepatoprotective activity. The purpose of this study was to determine the total flavonoid levels in raw pineapple juice (Ananas comusus L.Merr) by UV-Vis Spectrophotometry. The method used in research is the colorimetry method. Identification of flavonoids with concentrated HCl reagents and magnesium metal which changes color to red which indicates a positive sample containing flavonoids. The results of the study showed total flavonoid levels contained in raw pineapple juice with an average flavonoid level of 0,00027367% QE.
