[Two new glycosides from Erigeron breviscapus (Vant.) Hand.-Mazz].

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: Compounds VI and VII were new compounds.
