ABSTRACT
Objective:
To evaluate the toxicological safety of over-ground parts of Glycyrrhiza uralensis, in order to provide basis for the rational utilization of over-ground parts of Glycyrrhizae Radix et Rhizoma recourses.Method:
Mice acute oral toxicity test, micronucleus test of mice bone marrow, mice sperm shape abnormality test and toxicological test based on chronic nonbacterial prostatitis model were carried out.Result:
Maximal tolerable dose(MTD) of over-ground parts of G.uralensis water extract (WE) and alcohol extract (AE) were 96,128 g·kg-1, respectively. Macro-porous resin enriched product of AE was harmful to mice, with gender differences. Micronucleus rates of each dose(8,16,32 g·kg-1) group and control group for female mouse were 0.28%, 0.34%, 0.26% and 0.22%, respectively. Micronucleus rates of each dose(8,16,32 g·kg-1) group and control group for male mouse were 0.32%, 0.30%, 0.36% and 0.28%, respectively. Sperm shape abnormality rates of each dose group and control group were 3.16%, 3.01%, 2.67% and 3.23%, respectively. Micronucleus rate and sperm shape abnormality rate had no significant increase compared with the negative control. The 30-day repeated intragastric WE and AE had no effect on the general conditions of the model rats. Compared with normal group, AE group showed a significant decrease in heart weight, and significant increases in liver weight, liver index and kidney index (PPConclusion:
The results indicated that both of WE and AE have potential toxicity. WE does not show any genetic toxicity to mice. Therefore, further studies shall be made for toxicological safety of over-ground parts of G. uralensis.
