为了测定不同极性溶剂的甘草提取物对植物病原菌的抑菌作用。采用生长速率法研究了甘草的6种溶剂提取物对禾谷镰刀菌、尖孢镰刀菌、半裸镰刀菌、茄链格孢菌和立枯丝核菌的抑菌作用。结果表明，不同提取溶剂的提取率和抑菌作用存在明显差异。乙酸乙酯和丙酮提取物对尖孢镰刀菌均有较好的抑菌活性，分别是82.64%和83.13%。具有抑菌活性的成分可能为甘草黄酮类。

In order to determine the different polarity of solvent licorice extract on bacteriostatic action of plant pathogenic bacteria, the growth rate method was used to study the bacteriostatic effect of 6 licorice solvent extract to Fusarium graminearum,Fusarium oxysporum,Fusarium semitectum,Alternaria solani and Rhizoctonia solani. The results showed that the extraction ratio and the bacteriostatic effect of the different extraction solvents had obvious differences. The ethyl acetate and acetone extracts had better antibacterial activity than other solvents,and the bacteriostatic effect to Fusarium oxysporum are 82.64% and 83.13% respectively. So the antibacterial substances could be the licorice flavonoids.
