Abstract
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:
