Solani. The extract was further separated into two parts and one part separated by ethyl acetate while the other was separated by petroleum ether. Based on the inhibition experiment against R. solani, ethly acetate extract has a rather strong effect on R. solani with 89.70% inhibition rate and 15.52 mgmL^(-1) EC 50.The effect of petroleum ether extract on R. solani is relatively weak. The former was again divided into five parts in silica gel column, of which the second part significantly inhibits R. solani. During the periods of 24 and 48 hrs, the inhibition rate of the second part on R. solan is respectively 89.58% and 80.36%.

结果表明：鸭粪乙醇提取物对水稻纹枯病菌有抑制作用，24h内最高菌丝生长抑制率和EC50分别为88.64%、26.11mgmL^(-1)；鸭粪乙醇提取物经萃取分离得到石油醚和乙酸乙酯两种组分，其中石油醚组分抑菌效果较弱，乙酸乙酯组分抑菌能力较强，其对水稻纹枯病菌抑制率为89.70%，EC50为15.52mgmL^(-1)；对乙酸乙酯组分进行硅胶柱层析分离得到5种流份，其中第2流份有显著抑菌活性，在24h和48h内对水稻纹枯病菌的抑制率分别为89.58%和80.36%。
