摘要选取云南、贵州、河南的经不同工艺处理生丝、薄板干燥、高温气流干燥的烟丝；采用微波协助萃取技术进行样品的前处理；经活化的阳离子交换柱进行纯化，再用柱前衍生反相高效液相色谱的方法对其游离态氨基酸进行含量分析。 - The antimicrobial secretion could be divided into three sections , every section had antimicrobial activity . the first could be extracted by petroleum ether , the second could be extracted by ethyl alcohol , the third could dissove in water and could be separated by sephadex g - 50 , g200 gel filtration chromatography and carbornmethyl cellulose - 1 anion - exchange chromatography and detected by a256 , . the antimicrobial secretion had wide spectrum and had strong inhitory activity against germs and fungi , they could inhibit sixteen kinds of plant pathogenic germs , eight kinds of animal germs and eight kinds of plant pathogenic fungi
粗提物经石油醚萃取可得第一个活性部分，剩余部分经无水乙醇萃取可得第二个活性部分，剩余物质再经凝胶sephadexg - 50后有两个峰，第二峰有活性，再经凝胶sephadexg - 200后有三峰，第二峰有活性，将其经过阳离子交换柱cm - 1后有两峰，此两峰均有抑菌活性。
