Colony Stimulating Factor-Inducing Activity of Hesperidin

Abstract

To evaluate immunomodulating activities of bioflavones, colony-stimulating factor (CSF)-inducing activity of two dihydroflavones, three flavones and three flavonols were tested. These samples were suspended in saline and injected intraperitoneally (i.p.) into mice at a dose of 1 mg 6 h before bleeding. All compounds carrying the glucosyl-rhamnose moiety showed potent activity. Among them, hesperidin exhibited the strongest activity. Serum CSF production in mice injected with 1 mg hesperidin reached a peak at 9 h later. The activity of hesperidin was dose-dependent at a range of 0.3 to 20 mg/mouse.
