核桃叶乙醇提取物对菌类化感抑制的研究

Objective]The allelopathy of the extract from Walnut leaf alcohol to microorganism was researched.[Method]The extracts from the walnut leaf were obtained by distillation method for studying its antibacterial and antifungal activities. Use filter paper methed to detect the bacteriostatic effect of extract of alcohol.[Result] The extract from the walnut leaf alcohol had the remarkable inhibitory action to the Staphylococus, Bacillus subtilis, Rhizopus and Aspergillus and inhibitory action was enhanced with the concentration-increasing of extract from Walnut leaf alcohol.The result also showed that the bacteriostasis of the different bacterias was different with the same concentration. With the time going, antibacterial effect was weaker. [Conclusion] The extract from Walnut leaf alcohol had the varying degrees inhibitory action to the four bacteria and fungus tested and to provide experimental basis for the development of a series of related products such as the fungicide, biological pesticide, herbicide, biological experiments inhibitors, antihypertensive drugs.
