Studies on the Constituents in Lysimachia Congestiflora / 中药新药与临床药理

ABSTRACT

Objective To investigate the constituents in Lysimachia congestiflora.Methods The constituents were isolated by the silica gel column chromatography,and their structures were identified by spectroscopy methods.Results ?-Stigmasterol(1),quercetin(2),myricetin 3′-methyl ether(3),syringetin-3-O-?-L-arabinofuranosid(4),ardicrenin(5) and ardisiacrispin A(6) were isolated and identified.Conclusion Six compounds have been isolated from Lysimachia congestiflora,and ardicrenin(5) is isolated from this species for the first time.
