本文对败酱皂甙及其甙元的一般药理作用进行了研究。败酱皂甙是败酱(Patrinia scabiosal-folid)中的主要成份,其他败酱属植物中同样含有败酱皂甙。败酱皂甙是十一位碳上的羟基结合葡萄糖的环烯醚萜甙类化合物。败酱皂甙不同给药途径的LD_(50)分别为595毫克/公斤(静注)、350毫克/公斤(皮下)、555毫克/公斤(腹腔)、2克/公斤(口服)。其皂甙元的LD_(50)分别为143毫克/公斤(静注)、234毫克/公斤(皮下)、182 相似文献

Saikosaponins had marked suppressive ef-fect upon allergic inflammation,such as PCAreaction,Arthus reaction,adjuvant arthritis anddelayed hypersensitiveness.It had no obviouseffect on the antibody titre level and the amountof immune complexes in the serum of experi-mental rats in Arthus reaction or on the pha-gocytosis of the reticuloendothelial system ofexperimental mice.Saikosaponins solution did,however,decrease the leucocyte count and theamount of histamine and PGE in the inflamma-tory exudates of the Arthus reaction and blockthe release of histamine.Experimental resultsindicated that the suppressive action of Saikosa-ponins on allergic inflammation was due mainlyto the suppression of the synthesis,release andaction of inflammatory mediators such as his-famine,PGE and 5-HT of the inflammatoryprocess in the later stage of allergic reaction.No obvious effect on the humoral and cellularimmunity was noted. 相似文献
