为开发新资源,造福于人类,我们对野生植物刺老鸭进行开采,探讨研究。、性急毒性试验: (小鼠经口LD50测定)试验结果:五组试验动物染毒后两周均未见死亡,故该样品LD50>15000mg/kg,按我国食品毒理学六分级法属无毒。二、蓄积性毒性试验: (蓄积系数法)试验结果:累计剂量已超过5倍LD50,即K值大于5,动物仍没死亡,则可认为刺老鸭毒性甚小,或无蓄积性。三、致突变试验: (1)微核实验:
To develop new resources for the benefit of mankind, we have explored and explored the wild plant thorn ducks. , acute toxicity test: (mice oral LD50 determination) test results: five groups of experimental animals did not see death after two weeks of exposure, so the sample LD50> 15000mg/kg, according to China’s food toxicology six classification is non-toxic . Second, the cumulative toxicity test: (accumulation coefficient method) test results: cumulative dose has been more than 5 times the LD50, that is, K value is greater than 5, the animal has not died, you can think that the stab old duck toxicity is very small, or no accumulation. Third, the mutagenicity test: (1) micronucleus experiment:
