Abstract

Abstract: The water extract of Enshi Se-enriching Tengcha(ESTC) on the animal safety was investigated according to the Standard of Health Food Test and Assess. Acute toxicity test on mice showed that LD₅₀ was greater than 30βg/kg.bw. Three genetic tests showed negative results. 90 days feeding test showed that the outer appearance, behavior, weights, organ coefficients, the indexes of hematology and biochemistry in rats have no significant difference comparing with the control group. Significant pathological changes of inherent organs were not discovered. All results showed that ESTC was safet for rats.

Key words: Ampelopsis grossedentata, Enshi, Toxicity, Genetic tests, Toxicology assessment on safety
