摘要:

对西藏凹乳芹根、叶提取物进行急性毒性及亚急性毒性实验研究,先经预试验确定给药组数和剂量,然后灌胃给药,测试西藏凹乳芹根、叶提取物的半数致死量(LD50)及最大耐受量(MTD);再分别以LD50的1/20和1/40剂量连续灌胃给药做亚急性毒性实验。结果显示,西藏凹乳芹根和叶提取物的LD50分别为154.81和 58.27 g/kg,MTD分别为108.28和32.62 g/kg。西藏凹乳芹根、叶提取物的亚急性毒性实验各组的血液生化指标、脏器指数、体重及摄食量与对照组相比均没有明显变化。因此,西藏凹乳芹根、叶提取物属无毒级,长期服用未发现毒性反应,有较高的食用安全性。

Abstract:

To evaluate the acute toxicity and subacute toxicity of extracts from roots and leaves of Vicatia thibetica de Boiss.in mice.The number and dosage of the drug groups were determined by pre-test,and were administrated by gavage to test the LD50 and MTD of the extracts from roots and leaves of V. thibetica.The subacute toxicity experiments were carried out by gavage of 1/20 and 1/40 of LD50.The results showed that the LD50 of the extracts from the roots and leaves were 154.81 and 58.27 g/kg,and the MTD of the extracts from the roots and leaves were 108.28 and 32.62 g/kg,respectively.There were no significant changes in blood biochemical indexes,organ index,body weight,and food intake in the subacute toxicity experiment group compared with the control group.Therefore,the extracts from the roots and leaves of V. thibetica were of non-toxic grade with high edible safety,and no toxic reaction was found after long-term use.

Key words: Vicatia thibetica de Boiss., acute toxicity, subacute toxicity, half lethal dose, maximum tolerance ,
