摘要
为调查黄连花薹作为可食用资源的安全性,开展了黄连花薹及其主要生物碱的急性毒性和亚急性毒性试验.在急性毒性试验中,用20 000 mg/kg黄连花薹提取物和743.2 mg/kg生物碱混合物分别灌胃KM小鼠,14 d内未发现任何毒性反应且无动物死亡现象.在亚急性毒性试验中,以500、1 000、2 000 mg/kg 3个剂量的黄连花薹提取物及37.16 mg/kg的生物碱混合物分别灌胃SD大鼠28d,对照组和各处理组的动物体重和器官相对质量没有显著性差异,生化、血液和尿液指标检查均在正常范围内,主要脏器无病变,而且未观察到动物死亡现象.上述实验结果证明了黄连花薹作为药食同源原料的安全性.
Abstract
In order to study the safety of Coptis chinensis inflorescence as an edible raw material,the acute and sub-acute oral toxicities of C.chinensis inflorescence extract(CE)and its main alkaloids(MIX)were tested.KM mice were orally administered with 20 000 mg/kg CE or 743.2 mg/kg MIX for 14 days,and no toxicity or mortality was observed.SD rats were orally administered with three different doses of CE(500,1 000,2 000 mg/kg)and the alkaloids mixture(37.16 mg/kg)for 28 days.There was no significant difference detected in animal weight and organ relative weight between the control group and the treat-ment groups.The serum biochemical,hematological and urine parameters of all groups were examined and found to be within the normal ranges.Finally,the main organs did not present any histopathological lesions,and no animal death was observed.Based on these results,the safety of C.chinensis inflorescence as a medicinal and food homologous raw material can be ensured.
