In older to gain the optimization extract of polysaccharide of Rana chensinensis David by pulsed electric field (PEF), we have inspected single factor influence and then optimized them by orthogonal experiment.

Acute toxicity of Cu~(2+) and Cr~(6+) to Rana chensinensis tadpoles;

Toxic effect of cadmium on renal microstructure of Rana chensinensis;

Inductive effects of cadmium chloride on micronuclei and nuclear anomalies in erythrocytes of Rana chensinensis;

The optimal condition for Temperaria chensinensis polysaccharides(TCPS) extraction from the head of Chinese forest frog was with 20% of enzyme preparation, at pH 9 0 and 50℃ for 6 hours, which was determined through the positive crossing test.

There can be found Chinese Forest Frogs and Heilongjiang Forest Frogs in the Northeast of China.

Chinese Forest Frog (Rana chensinensis) is a kind of important amphibian in China and also one of the most important medical animals of Hei Longjiang Province.
