摘　　要：研究了三种豆科牧草刺叶锦鸡儿、白皮锦鸡儿和盐豆木地上部分乙醇提取物及其不同极性萃取部分对水稻纹枯病菌和小麦纹枯病菌的抑制活性。白皮锦鸡儿的抗菌活性相对较好，盐豆木中等，刺叶锦鸡儿的活性较弱。它们的乙醇粗提物和各萃取部分对小麦纹枯病菌的抑制活性普遍要强于对水稻纹枯病菌的抑制活性。三种植物的乙酸乙酯萃取部分对两种纹枯病菌具有较好的抑制活性，推测它们的抗菌活性成分主要存在于乙酸乙酯萃取组分中，为中等极性的化合物。The crude ethanol extracts and different polar fractions of three leguminous forages （ i. e. Caragana acantho- phylla,C, leucophloea and Halimodendron halodendron） in Xinjiang Province of China were studied for their inhibitory activity on Rhizoctonia solani and 17. cerealis. Of＇ three plants, C. leucophloea showed its strong anfifungal activity,and H. halodendron showed its moderate activity, and C. acanthophyUa showed its relatively weak activity. All the extracts and fractions of three plants were screened to show .＇~tmnger inhibitory activity on R. cerealis than that on R. solani. Of all the fractions of three plants,ethyl acetate fractions were found to have the strongest antifungal activity. It suggested that the antifungal components with their moderate polarity mainly existed in the ethyl acetate fractions of three plant species
