Flavanone Glycosides from Citrus junos and their Anti-Influenza Virus Activity

Abstract

By bioactivity-guided fractionation, a new flavanone triglycoside, naringenin 7-O-(2″,6″-di-O-α-rhamnopyranosyl)-β-glucopyranoside (1), as well as hesperetin 7-O-(2″, 6″-di-O-α-rhamnopyranosyl)-β-glucopyranoside (2), hesperidin (3) and narirutin (4) have been isolated from the fruits of Citrus junos Tanaka (Rutaceae). In addition, hesperetin 7-O-(2″,6″-di-O-α-rhamnopyranosyl)-β-glucopyranoside (2) is reported for the first time from this plant and inhibits the influenza A virus.
