Abstract:

Objective: To explore if chlorogenic acid (CHA) could ameliorate intestinal mitochondrial damage in rats. Methods:
Intestinal mitochondria of rats were treated with hydrogen peroxide. The mitochondrial swelling, membrane potential, MDA content,
T-SOD and GSH-Px activities, and the enzymatic activities of mitochondrial respiratory chain complexes Ⅰ, Ⅳ, and Ⅴ were
evaluated. Results: CHA significantly inhibited mitochondrial swelling caused by hydrogen peroxide and reduced cell membrane
potential. CHA (0.032 mg/mL and 0.064 mg/mL) significantly decreased the concentration of MDA when compared with the control
group. The activities of T-SOD, GSH-Px and complex Ⅰ in the CHA group (0.064 mg/mL) were significantly increased when
compared with the control group. Conclusion: CHA can attenuate mitochondrial damage induced by hydrogen peroxide through
increasing the activities of mitochondrial respiratory chain complex enzymes and antioxidant enzymes.

Key words: chlorogenic acid, mitochondria, oxidative damage, respiratory chain complex
