ABSTRACT

Objective:

To investigate the effect of different extracts of Lysimachiae Herba on the main toxicity induced by Tripterygii Radix et Rhizoma.

Method:

Ninety male SPF Kunming mice were randomly divided into 9 groups according to their body weightcontrol group, Lysimachiae Herba water extract group, Lysimachiae Herba 30% ethanol extract group, Tripterygii Radix et Rhizoma group, Tripterygii Radix et Rhizoma combined with Lysimachiae Herba water extract group, Tripterygii Radix et Rhizoma combined with Lysimachiae Herba 30% ethanol extract group, Tripterygii Radix et Rhizoma combined with Lysimachiae Herba 60% ethanol extract group, Tripterygii Radix et Rhizoma combined with Lysimachiae Herba 95% ethanol extract group and Tripterygii Radix et Rhizoma combined with Lysimachiae Herba ethyl acetate extract group. The dosage of Tripterygii Radix et Rhizoma and Lysimachiae Herba were 2,1 g·kg<sup>-1</sup> based on crude drugs, respectively. The control group was given an equal volume of solvent, and each group was given by gavage for 14 consecutive days. The blood and liver tissues were taken 24 hours after the last administration. The enzyme linked immunosorbent assayELISA) was used to detect serum biochemical indexes and liver lipid peroxidation/antioxidant indexes in mice. Meanwhile, principal component analysis was used to evaluate the attenuating effect and the mechanism of Lysimachiae Herba extract on toxicity of Tripterygii Radix et Rhizoma.

Result:

Compared with control group, Tripterygii Radix et Rhizoma caused the levels of alanine aminotransferase(ALT),aspartic acid amino transferase(AST),alkaline phosphatase(ALP) in serum of mice, and the levels of malondialdehyde (MDA) in liver, and comprehensive score of toxicity (Z value) produced by the above four indexes increased significantly (<italic>P</italic><0.01). The levels of total superoxide dismutase (T-SOD),glutathione-peroxidase (GPX),glutathione-S transferase (GST) decreased significantly (<italic>P</italic><0.01) in liver. Compared with Tripterygii Radix et Rhizoma group, after intervention with extracts of two solventswater, 30% ethanol) of Lysimachiae Herba, the levels of serum ALT, AST, ALP and liver MDA were significantly decreased (<italic>P</italic><0.05, <italic>P</italic><0.01), while the levels of liver T-SOD, GPX and GST were significantly increased (<italic>P</italic><0.01). After intervention with extracts of two solvents (60% ethanol, 95% ethanol) of Lysimachiae Herba, the levels of serum ALT, AST, ALP were significantly decreased (<italic>P</italic><0.01), and liver GPX levels were significantly increased (<italic>P</italic><0.01). After the intervention with ethyl acetate extract of Lysimachiae Herba, only the level of serum AST was significantly decreased (<italic>P</italic><0.05) and the level of GPX was significantly increased (<italic>P</italic><0.05). After the intervention with extracts of different solventswater, 30% ethanol, 60% ethanol, 95% ethanol, ethyl acetate) of Lysimachiae Herba, it can significantly reduce the comprehensive score of toxicity (<italic>P</italic><0.01). The overall decline rates of toxicity were 127.5%, 113.4%, 98.1%, 56.3% and 31.0% respectively. Among them, the toxicity reduction rate of the extracts with water as a solvent was 14.1%, 29.4%, 71.2%, 96.5% higher than those of other solvent extracts with ethanol.

Conclusion:

The extracts of different solventswater, 30% ethanol, 60% ethanol, 95% ethanol and ethyl acetate) of Lysimachiae Herba can reverse the toxicity induced by Tripterygii Radix et Rhizoma in varying degrees. Among them, water and 30% ethanol are the best solvents for detoxification, especially water as the extraction solvent, and with the increase of ethanol content or fat solubility of extraction solvent, the detoxification shows a downward trend.
