n-hexane as solvent. The material that has been submerged in petroleum ether is wrapped in
filter paper and then tied with thread. Then it is put into the socket extractor. Furthermore, the
flavonoid and antioxidant levels were tested. The highest flavonoid content in taro leaves was
obtained by maceration method with ethanol solvent, as much as 12.836 mg QE/g. The highest
