Abstract
Hesperetin, an important bioactive compound in Chinese traditional medicine, has antioxidant and anticarcinogenic properties. Hesperetin is found in abundance in orange and grape juices (200–590 mg L−1) consumed in the daily diet. We have investigated the effect of different doses of hesperetin on faecal and colonic mucosal bacterial enzymes and aberrant crypt foci (ACF) in 1,2‐dimethylhydrazine (DMH)‐induced colon carcinogenesis in male Wistar rats. The rats were divided into six groups and were fed a modified pellet diet for 16 weeks. Group 1 served as control and group 2 received the modified pellet diet along with hesperetin (30 mg kg−1). The rats in groups 3–6 rats were given a weekly subcutaneous injection of DMH (20 mg kg−1) for the first four weeks. Hesperetin was supplemented orally at different doses (10, 20 or 30 mg kg−1) for a total of 16 weeks. At the end of the experimental period all rats were killed. In DMH‐treated rats, the activity of faecal and colonic mucosal bacterial enzymes, such as β‐glucuronidase, β‐galactosidase, β‐glucosidase, nitroreductase, sulfatase and mucinase, were significantly elevated, but in rats supplemented hesperetin along with DMH the activity was significantly lowered (P < 0.05). The total number of aberrant crypts was significantly increased in unsupplemented DMH‐treated rats, while hesperetin supplementation to DMH‐treated rats significantly reduced the total number of crypts. The results demonstrated that hesperetin supplementation at a dose of 20 mg kg−1 played a potent role in suppressing the formation of aberrant crypt foci and reducing the activity of bacterial enzymes in colon cancer.
