Evaluation of eugenol for mutagenicity by the mouse micronucleus test
Journal of Oral Pathology
|September 1, 1986
Summary
Eugenol, a compound found in cloves, showed mutagenic potential in mice. Both intraperitoneal and oral administration induced genetic mutations, indicating a need for further toxicological evaluation.
Area of Science:
- Toxicology
- Genetics
- Pharmacology
Background:
- Eugenol (2-methoxy-4-allylphenol) is a naturally occurring phenolic compound.
- Its mutagenicity in eukaryotic systems requires thorough investigation.
Purpose of the Study:
- To evaluate the in vivo mutagenicity of eugenol in mice using the bone marrow micronucleus test.
- To compare the mutagenic effects of intraperitoneal (IP) and oral (PO) administration routes.
Main Methods:
- Determined the 50% lethal dose (LD50) for IP and PO eugenol administration in male mice.
- Administered 80% and 25% LD50 doses via IP route and undiluted eugenol via PO route.
- Assessed mutagenicity by quantifying micronuclei formation in polychromatic erythrocytes.
Main Results:
- Both IP and PO eugenol administration induced significant increases in micronuclei formation compared to controls (P < 0.001 for IP, P < 0.003 for PO).
- IP delivery resulted in a higher frequency of micronuclei compared to the PO route.
- The LD50 for IP eugenol was 1109.6 mg/kg, while oral administration was not lethal up to 14,794 mg/kg.
Conclusions:
- Eugenol exhibits mutagenic capacity in eukaryotic hosts.
- The route of administration influences the observed mutagenic effects.
- Further toxicological studies are warranted to fully assess the risks associated with eugenol exposure.
