英文摘要：

Objective To study the chemical constituents of Laggera pterodonta（ DC.） Benth.. Methods Various chromatographic methods were applied to isolate and purify the ethnol extract of the aerial parts of Laggera pterodonta. Their structures were identified by chemical and spectral analysis. Results Six flavonoids were obtained and their structures were elucidated as 5,6-dihydroxy-3,7,4＇-trimethoxyflavone（1）, artemitin（2）,casticin（3）, 5,4＇-dihydroxy-6,7-dimethoxyflavone（4）, penduletin（5） and chrysosplenetin B（6）. Conclusion Compounds 1, 3 and 4 were isolated from the plant for the first time.
