Abstract :
Flavonoids in tomato juice has been scientifically proven to have antioxidant activity. Flavonoid can reduce LDL (Low Density Lipoprotein) cholesterol and hypertension. The purpose of this study given information the compound of flavonoids in tomato juice (Lycopersicum esculentum Mill.). Extraction of flavonoids was done using the methanol solvent. Determination of total flavonoids compound was done using UV-Vis Spectrophotometer at 439,8 nm with the operating time 32 minutes until 40 minutes. The analysis showed that the average level of total flavonoids in tomato juice is 20,2963 mgQE / 100 gram of tomatoes and Coefficient of Variation that was 0,3628 %.
