OBJECTIVE
To study the chemical constituents from the upground part of Erigeron breviscapus.
METHOD
The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR.
RESULT
Two new compounds were isolated and identified as 5,4'-dihydroxy flavonod-7-O-beta-D-pyranglycuronate buthyl ester(VI) and 3,5-dimethoxy benzene carbonic acid-4-O-beta-D-pyranglucose(VII).
CONCLUSION
Compounds VI and VII were new compounds.
目的
研究灯盏花地上部分的化学成分。
方法
采用硅胶柱色谱法对化合物进行分离纯化，并通过红外光谱（IR）、质谱（MS）、核磁共振（NMR）和二维核磁共振（2D-NMR）进行鉴定。
结果
分离得到两个新化合物，分别鉴定为5,4'-二羟基黄酮-7-O-β-D-吡喃葡萄糖醛酸丁酯（VI）和3,5-二甲氧基苯甲酸-4-O-β-D-吡喃葡萄糖（VII）。
结论
化合物VI和VII为新化合物。
