After the acet is vaporized, the active substance in water is gotten. and which is vaporized at low temperature. then the crude active substance is purified by column chromatography on sephadex g - 75. after a series of purifications again, we could get some white powder at last. though the active substance is diluted to50 g / ml, the activity is still checkeded - up through phyto phtnora casicileon. the purified active substance is insensitive to heat, resistant to chloroform 、 ethanol and the orhers. in addition, the active substance is sensitive to high ph ( 10 ~ 14 ), but it is not sensitive to low ph ( 1 ~ 5 ). furthermre, when the ph is made to low again, the activity of it ' s comes back
用蒸餾水對菌體稀釋；加入適量吸附樹脂在150rpm 、 28下振蕩吸附4h ， 80 %的丙酮解吸，過濾解吸液得到活性物質的澄清溶液，旋轉蒸發儀旋轉蒸發去處丙酮，經sephadexg - 75分子篩層析得單一活性峰，收集峰值部分樣品液經冷凍乾燥得到淡褐色粉末，該活性物質用丙酮充分洗滌、甲醇-乙醚重結晶獲得略帶微黃的白色粉末，該活性物質50 g / ml仍可對蘇雲金芽孢桿菌hd - 1產生明顯的抑制作用。
