| Abstract: | The aim of the experiment was to observe the liver toxicity of different polarity section extracts from Aster tataricus L.f.on SD rats.The subchronic test was performed via the daily oral administration of Aster tataricus L.f.at dose of 0.34 g/kg body weight in SD rats which were divided into six groups(control group, petroleum ether group, ethyl acetate group, N-butyl alcohol group, mother liquid group and 75% ethanol group), observing the effects on food consumption, body weight gain, viscera coefficient, urine examination, blood routine examination, serum biochemistry indices, liver antioxidant function analysis and histopathological observation.There was no significant changes of body weight gain, viscera coefficient, urine examination and liver antioxidant function among six groups(P>0.05), but WBC significantly and extremely significantly decreased in male rats of ethyl acetate group, mother liquid group and N-butyl alcohol group(P<0.05; P<0.01), and significantly and extremely significantly decreased in female rats of N-butyl alcohol group and petroleum ether group, ethyl acetate group(P<0.05; P<0.01);The LDH significantly increased in female rats of ethyl acetate group(P<0.05);Slight congestion and necrosis were showed in liver in petroleum ether group and ethyl acetate group, there was no differences observed in other groups.The extracts of Aster tataricus L.f., especially petroleum ether extract and ethyl acetate extract could cause slight liver toxicity under the dose of 0.34 g/kg body weight. |
