Objective: Chrysin and rutin are two dietary flavonoids lying in fruits or honey bee’s products. Their pharmacological properties include antioxidant, anti-inflammatory, anticancer, neuroprotection and immunomodulatory. In the current study, the potentiality of chrysin and rutin to protect human gingival fibroblasts against oxidative cell damage has
been investigated in vitro.
Method: Human gingival fibroblasts, passage 3, were concomitantly put in contact with the cytotoxic compounds and chrysin or rutin for 24 h at 37 °C, 5% CO2 atmosphere, and 96% humidity. The amount of viable cell after the incubated time was recorded by using the thiazolyl blue tetrazolium bromide (MTT) assay.
Results: Chrysin in all tested concentration didn’t exhibit any cytoprotective effect against the tert-butyl hydroperoxide-induced oxidative cell damage. Moreover, chrysin in a low concentration (5 and 10 µg/mL) didn’t protect the fibroblasts against oxidative cell damage induced by the hydrogen peroxide. However, chrysin in a concentration of 20 µg/mL showed a significant cytoprotective activity in the hydrogen peroxide-induced cell damage (p
