Abstract
Objective Wungu leaves contain flavonoids that has an crucial role in human health. The flavonoids were obtained through an extraction process. The extraction method that requires a short time but can produce optimal extract conditions is the sonication. One of the factors of the extraction process is the type of solvent. Flavonoids can dissolve in polar extraction solvents. The prior research has proven the presence of flavonoids in the extraction solvents of purple leaf, namely aquades, 30% ethanol, 50% ethanol, and 70% ethanol. This goal is to determine the optimal type of extraction solvent for purple leaves based on the highest total flavonoid content through the sonication extraction method. Method The wungu leaves were extracted using aquades, 30%, 50%, and 70% ethanol; and 2M HCl was added to assist the hydrolysis process. Then, the total flavonoid content was calculated using a Nano Spectrophotometer after sonication. Result The total flavonoid value in the 70% ethanol solvent group was superior (0.2515 mg QR/g DW). Based on the One-Way ANOVA Hypothesis test, the results indicate a difference between two or more groups with a significance of 0.006. Conclusion It can be assumed that there is a new finding that extraction conditions can be optimized using 70% ethanol solvent.
