摘要
药用植物红景天提取物具有抗高寒、抗疲劳、抗缺氧等作用,可作为食品新资源开发利用.以红景天0.8、1.6、3.2g/kg 体重分别给怀孕大鼠灌胃,结果除阳性对照组外,各实验组均未出现畸胎.本试验结果为红景天饮料的毒理学安全性评价提供了科学依据.
The extract of rhodiola appear to be effective to help the body to resist and tolerate low temperature,fatigue and oxygen hungry.We propose that it might be possible to be used as a new food resourses and supplement.In our study the extract of rhodiola was given to groups of pregnant rats by stomach-tubing in doses of 0.8g,1.6g and 3.2g/kg of body weight re- spectively.The results showed that there were no teratogenic effects for the experimental groups and the negative control group.However,teratogenic effects for the positive control group was obvious.This results provide the scientific evidence for the evaluation of toxicolo- gy and safety of rhodiola containing beverage.
