Antioxidant and Antitumor Activities of Methanolic Extracts from Humulus japonicus

Abstract

To evaluate the antioxidant and potential of Humulus japonicus, total polyphenol and flavonoid content, radical scavenging activities, and antitumor activities were measured. The total polyphenol and flavonoid contents of the methanol extracts from Humulus japonicus were <TEX>$30.13{\pm}1.13$</TEX> and <TEX>$13.61{\pm}0.49$</TEX> mg gallic acid equivalent/g extract, respectively. DPPH radical and hydroxyl radical scavenging activities of methanol extracts of Humulus japonicus were 60% and 35%, respectively. The Humulus japonicus higher activities of anticancer activities on liver cancer cell lines compared to other cancer cell lines.
