Synergistic effect ofSacoglottis gabonensis bark extract.

Area of Science:

• Toxicology
• Pharmacology
• Natural Products Chemistry

Background:

• Aflatoxin B1 is a potent carcinogen requiring understanding of its metabolic pathways.
• Sacoglottis gabonensis is a plant with traditional medicinal uses.
• Ethanol is a common co-ingestant with potential to alter xenobiotic metabolism.

Purpose of the Study:

• To investigate the influence of Sacoglottis gabonensis aqueous bark extract and ethanol on the metabolism of aflatoxin B1 in rats.
• To determine potential synergistic interactions between the plant extract and ethanol in modulating aflatoxin B1 biotransformation.

Main Methods:

• Weanling male Fischer F344 rats were administered Sacoglottis gabonensis extract, ethanol, or both for 7 days.
• Microsomal and cytosolic fractions were isolated to assay aflatoxin B1 metabolism, including dihydrodiol, Q1, M1, Pi, protein adducts, and glutathione conjugation.
• Liver glutathione content was measured to assess cellular detoxification capacity.

Main Results:

• Pretreatment with Sacoglottis gabonensis extract or ethanol alone increased aflatoxin M1 production compared to controls.
• Combined extract and ethanol treatment significantly enhanced both aflatoxin M1 and Q1 production.
• All treatments led to significant reductions in hepatic glutathione levels, suggesting increased oxidative stress or conjugation activity.

Conclusions:

• Sacoglottis gabonensis extract, particularly in combination with ethanol, can significantly alter aflatoxin B1 metabolism in rats.
• The observed increase in aflatoxin M1 and Q1 suggests enhanced bioactivation or altered detoxification pathways.
• These findings highlight the potential for synergistic interactions between natural products and ethanol to influence toxicological responses to mycotoxins.
