Abstract:

OBJECTIVE:The genotoxicity of essential oil from Chenopodium ambrosioides L. was evaluated with TK gene mutation test to provide information for its safety. METHODS:The mouse lymphoma cells L5178Y were exposed to essential oil of C. ambrosioides at volume fraction concentrations of 0.002%, 0.004%,0.006% and 0.008% for 3 h. 1% dimethyl sulfoxide (DMSO) and 10 μg/mL cyclophosphamide (CP) were used as solvent and positive controls,respectively. TK gene mutation was assessed with microwell method to detect cytotoxicity and mutation frequency at TK locus in L5178Y cells. RESULTS:Relative survival (RS),relative suspension growth (RSG) and relative total growth (RTG) decreased when concentration of essential oil from C. ambrosioides increased,with only 29.38%,38.13% and 5.75%,respectively,in 0.008% dose group indicating significant cytotoxicity. Compared with the solvent control mutation frequency (TMF) increased with the rising concentration of essential oil(F=410.5,P=0.00). Multiple comparisons of TMT between the different essential oil groups,positive control group and solvent control group were statistically significant differences (P<0.05). The percentage of small growth mutant (SCM) was more than 95%. CONCLUSION: Essential oil from C. ambrosioides showed strong cytotoxicity and could increase mutation frequency at TK gene locus in L5178Y cells.
