Objective:
To investigate the effect of high doses apigenin on antioxidase activity of and DNA oxidative damages in rats.
Methods:
100 Wistar rats were randomly divided into five groups including control, dose one to four groups. The trial lasted 13 weeks, the blood samples and liver of rats were collected at the end of the experiment. The activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione-S-transferase (GST) and levels of malondialdehyde (MDA) were determinde, 8-OHdG content, which is indicative of DNA damage were assessed.
Results:
At 2 g/kg and 4 g/kg apigenin, the activity of SOD and GSH-Px in male rat liver significantly decreased, at 2 g/kg bw dose, the activity of male rat liver GST also greatly decreased. At the dose of 4 g/kg apigenin, GSH-Px activity in serum of both sex rats significantly decreased, its male rat GST activity at dose of 8 g/kg apigenin also greatly decreased.
Conclusion:
High dose apigenin could decrease antioxidase activity of male rat, but, it didn't cause DNA damage.
