6种中草药水提取物对兔球虫卵囊孢子化的影响

为了研究石榴皮、白头翁、青蒿、紫茎泽兰、秦皮、五倍子等6种中草药水提取物对兔球虫卵囊孢子化的影响,选用0.25、0.5、1.0 g/m L的单味药物对未孢子化的兔球虫进行体外抑制试验,连续7 d观察18个试验组球虫卵囊孢子化的情况。结果表明,所选用的6种中草药对兔球虫卵囊孢子化具有不同程度的抑制作用,其中抑制效果最好的是1.0 g/m L的五倍子,抑制率为41%;其次是0.5 g/m L的秦皮,抑制率为30%;效果较差的是0.25 g/m L的紫茎泽兰和0.25 g/m L的石榴皮,抑制率分别为9%和8%;最差的是1.0 g/m L的石榴皮,抑制率仅为6%。

Effects ofAqueous Extracts of Six Kinds of Chinese Herbal Medicine on the Sporulating of Rabbit Coccidia Oocysts

Abstract: In order to understand the effects of aqueous extracts of six different kinds of Chinese herbal medicine including pomegranate peel, Pulsatilla chinensis, Artemisia annuae,Eupatorium adenophorum, Cortex fraxini and Galla chinensis on the sporulating of rabbit coccidia oocysts. Three different concentrations ( 0.25 g/mL, 0.5 g/mL and 1.0 g/mL) of single Chinese herbal medicine were chose to unsporulated rabbit coccidia oocysts in vitro, the sporulated numbers of rabbit coccidia oocysts were observed in 18 experimental groups for seven consecutive days. The results showed that the six kinds of Chinese herbal medicines had different inhibition effects on rabbit coccidia oocysts to sporulate. 1.0 g/mL of Galla chinensis had the best inhibition effect, the inhibition rate was 41 %; followed by 0.5 g/mL of Cortex fraxini, the inhibition rate was 30 %; 0.25 g/mL of Eupatorium adenophorum and 0.25 g/mLof pomegranate peel had a little inhibition effect, the inhibition rates were 9 % and 8%, respectively; 1.0 g/ mL of pomegranate peel had the worst inhibition effect, the inhibition rate was only 6 %
