Antimutagenic effect of methanolic extracts from peanut hulls
1Department of Food Science, National Chung Hsing University, Taiwan, Republic of China.
Abstract:
The antimutagenic effects of methanolic extracts of peanut hulls (MEPH) were evaluated by the Ames test. MEPH inhibited the mutagenicity of 4-nitroquinoline-N-oxide (NQNO), a direct-acting mutagen. MEPH also inhibited the mutagenicity of some indirect-acting mutagens and decreased in the order of 2-amino-3-methyl-imidazo(4,5-f)quinoline (IQ) > aflatoxin B1 (AFB1) > 2-amino-6-methyldipyrido(1,2-a:3',2'-d)imidazole (Glu-P-1) > 3 amino-1,4-dimethyl-5H-pyridol(4,3-b)indole (Trp-P-1) > benzo(a)pyrene (B(a)P for S. typhimurium TA98, and IQ > Trp-P-1 > Glu-P-1 > AFB1 > B(a)P for S. typhimurium TA100.
Insights
Methanolic extracts of peanut hulls (MEPH) show antimutagenic effects, inhibiting both direct and indirect mutagens. This natural compound demonstrates potential in reducing DNA damage from various harmful agents.
Area of Science:
- Food Science
- Toxicology
- Natural Product Chemistry
Background:
- Mutagens, such as 4-nitroquinoline-N-oxide (NQNO), pose risks to DNA integrity.
- Certain food components may possess antimutagenic properties.
- Peanut hulls are a byproduct with potential bioactive compounds.
Purpose of the Study:
- To investigate the antimutagenic potential of methanolic extracts of peanut hulls (MEPH).
- To evaluate the efficacy of MEPH against direct and indirect-acting mutagens using the Ames test.
Main Methods:
- The Ames test was employed to assess mutagenicity.
- Methanolic extracts of peanut hulls (MEPH) were prepared and tested.
- Inhibition of mutagenicity by MEPH against NQNO and various indirect mutagens was quantified.
Main Results:
- MEPH demonstrated significant inhibition of the direct-acting mutagen NQNO.
- MEPH also inhibited indirect-acting mutagens, including aflatoxin B1 (AFB1), IQ, Glu-P-1, Trp-P-1, and B(a)P.
- The order of inhibition varied between bacterial strains S. typhimurium TA98 and TA100.
Conclusions:
- Methanolic extracts of peanut hulls possess notable antimutagenic properties.
- MEPH can counteract the mutagenic effects of both direct and indirect mutagens.
- Further research into peanut hull extracts could yield natural antimutagenic agents.
