摘要: 目的对艾叶不同组分中主要成分含量及小鼠急毒大小进行比较研究,探讨不同提取方式对艾叶质量与毒性之间相关性的影响。方法分别制备挥发油、全组分、水提组分、醇提组分样品,运用药典挥发油测定法、UV法与经典的小鼠急毒试验方法,进行艾叶不同组分中主要成分挥发油及黄酮类的含量测定及急性毒性比较研究。结果艾叶中挥发油含量为0.76%,总黄酮含量大小依次为醇提组分>水提组分>全组分;艾叶不同组分对小鼠急性毒性强度为:挥发油>水提组分>醇提组分>全组分,挥发油与水提组分LD50按含生药量计算分别为1.673 mL·kg-1、80.228 g·kg-1,95%可信区间分别为1.5538~1.7954mL·kg-1、77.407~83.405 g·kg-1;醇提组分最大耐受量MTD为75.6 g·kg-1,相当于临床70 kg的成人每公斤体重日用量的588.0倍;艾叶全组分最大给药量MLD为24.0 g·kg-1,相当于临床70 kg的成人每公斤体重日用剂量的186.7倍。结论艾叶挥发油对小鼠可产生明显的急性毒性反应,是其毒性物质基础之一,不同组分中总黄酮含量存在显著性差异,但通过实验未发现其与小鼠急性毒性具有相关性,总黄酮是否会产生肝毒性尚需要进一步的研究确证。另外,除挥发油外艾叶毒性物质还包括一些水溶性及醇溶性成分,尚需进一步考察。关键词:艾叶;提取方式;挥发油;总黄酮;含量测定;急性毒性

Abstract: Objective By comparing the volatile oil, total flavonoids content and the acute toxicity of different extracts in Folium Artemisiae Argyi, to explore the effect of different extraction solvents on the quality and toxicity of Folium Artemisiae Argyi. MethodsBy using pharmacopeial determination of volatile oil method, UV and the classic acute toxicity experiment method, to determine the content of volatile oil and total flavonoids, as well as compare the acute toxicity of different extracts. ResultsThe content of volatile oil is 0.76%, while the total flavonoids content of different extracts from the biggest to the smallest is alcohol extraction components, water extraction components and all components. The acute toxicity of different extracts from the biggest to the smallest is volatile oil, water extraction components, alcohol extraction components and all components. The LD50 of volatile oil and water extraction components in Folium Artemisiae Argyi are 1.673 mL·kg-1 and 80.228 g·kg-1 while the 95% confidence limit are 1.5538 ~1.7954mL·
