Abstract:
Aim To assay the mutagenicity of Enphorbia lunulata(EL) decoction and to modify the Ames test for evaluation the mutagenicity of herbal medicine samples.Method The mutagenicity of EL decoction was assayed by standard Ames test; the teratogenicity was done by mammalian bone marrow chromosomal aberration test. In modified Ames test system,the influence of histidine EL decoction was excluded by additional negative control, in which the test media was supplied with histidine (histidine amount equaled to the histidine in different concentration of EL decoction).Result The mutagenicity of EL decoction was positive in the standard Ames test. The teratogenicity of EL decoction was negative in mammalian bone marrow chromosomal aberration test. By the modified Ames tests,the mutagenicity of EL decoction was negative.Conclusion The standard Ames test is not suitable for evaluating the mutagenicity of EL decoction, but the modified Ames test is. The mutagenicity in vitro and the teratogenicity in vivo of EL decoction are all negative.
