Aflatoxins are harmful compounds that induced carcinogenic impacts on tissues. It could generate oxidative stress causing cells damage. Bioactive substances from natural plants could avoid mycotoxins’ bad impacts. Cape-goldenberry (CGB), a source of active substances, was vacuum-dried at 30 °C then milled. Fresh and dried CGB-powder properties were estimated. Animal experiment was designed using six rat-groups to evaluate CBG effect to reduce harmful effect of aflatoxins. Rats treated groups were orally administrated by aflatoxins (AFs) with or without CGB in diets. Blood parameters, liver and kidney functions, serum lipids, and liver histological changes were estimated. The CGB powder showed several time doubles of phenolics, flavonoids, and antioxidants than fresh fruits. Diet supplementation by CGB of AFs-treated rats showed enhancement in final weight, food efficiency, and weight gain compared to AFs treatment only. Also, liver and kidney functions, liver enzymes, iron level, tumors indicator, and serum lipids of AFs- rats. Moreover, total protein, albumin, and globulin reduction by AFs have been improved by CGB presence in diets. Histopathological studies for AFs-rats liver showed dilated blood sinusoids with aggregation of inflammatory, Kupffer cell hyperplasia, degenerated hepatocytes, and apoptotic cells. However, in AFs-rat groups fed CGB in diets, liver hepatocytes appeared to be almost normal similar to the control. Results pointed out that CGB recorded a corrective action for aflatoxin B1 and G1 toxicity. This was recorded for the blood and serum parameters, and liver enzymes. This CGB action avoiding AFs-toxicity was more clearly declared in the liver tissues.
