摘要
对绞股蓝总皂甙(GPS)的研究表明:急性毒性>1000Omg/kg,各项致突变试验结果均为阴性;在GPS剂量为1000、2500,500Omg/kg时由环磷酰胺所致小鼠骨髓细胞微核率分别为11.9‰、8.5‰和13.6‰均较环磷酰胺组的29.9‰明显降低(P<0.05)。在5-50μg/皿范围内,GPS对TA98、TA100和TA102菌株经不同阳性物诱导后的菌落回变数有不同程度降低,对TA98菌株在2-AF(S9+)有良好的抗诱变作用,并呈剂量反应关系。结果提示,绞股蓝总皂甙在体内和体外均表现出明确的抗诱变作用。本文还对其抗诱变作用的可能机理进行了探讨。
The result showed that acute toxicity of GPS is over l0000mg/kg and has no
mutagenic potentialin the mutation assays. White animals were administrated GPS,the
micronucleus rate of PEC in mice bonemarrow induced by cyclophosphamide(CP)were
obviously inhibited.1000mg/kg 11.9‰,2500mg/kg 8.5‰,500Omg/kg 13.6‰ compared to CP 29.
9‰(P<0.05)。From 5-50mg/plate.GPS were also inhibited the re-version frequencies in strain
TA98,TA100 and TA102 by varied positive mutagens.GPS showed a good dose~respose
inhibition of revere mutation of strain TA98 induced by 2-AF(S9+).The results suggested
thatGPS have a possible antimugenesis in both vitro and vivo.The probable mechanism of
antimutagenesis of GPShas been suspected.
