摘　　要：研究了从长裙竹荪中提取一种生物防腐剂,最佳提取工艺条件为:长裙竹荪子实体粉碎过80目筛,加入95%乙醇经45kHz超声波处理20min,加入0.1%果胶复合酶酶解1h后,在80℃下,1∶15料液比浸提8h,收集滤液减压浓缩至无酒精挥出,得到的棕色膏状物具有明显的抑菌效果,尤其对革兰氏阳性菌和革兰氏阴性菌效果明显,但对酵母和霉菌基本无抑菌效果。This paper studies the biological preservatives from the gown Dictyophora, the optimum conditions： Dictyophora gown were shoot Fruitbody smash the heads of 80 screen, add ed 95 % ethanol , by trasonic treatment 45 kHz 20 min, added 0.1% pectin enzymatic hydrolysis of an hour later, at 80 ℃, 1：15 materials extraction fluid than eight hours to collect filtrate decompression without alcohol concentration to lead, by the brown paste of a significant inhibitory effect, especially against Gram-positive bacteria and gram-negative bacteria obvious effect, but without yeast and mold basic antibacterial effects.
