Object To investigate the chemical constituents of Lysimachia davurica Ledeb Methods The constituents were isolated by column chromatography and their structures elucidated by physicochemical properties and spectroscopic analysis Results Twelve components were isolated and identified as p coumaric acid (Ⅰ), 3, 5 dihydroxybenzoic acid (Ⅱ), quercetin (Ⅲ), quercetin 3 O β D glucopyranoside (Ⅳ), quercetin 3 O β D glucuronopyranoside ethyl ester (Ⅴ), chlorogenic acid ethyl ester (Ⅵ), chlorogenic acid butyl ester (Ⅶ), daucosterol (Ⅷ), quercetin 3 O β D galactopyranoside (Ⅸ), methyl β D glucopyranoside (Ⅹ), isorhamnetin 3 O rhamnopyranosylglucopyranoside (Ⅺ), and rutin ( ⅩⅡ ) Conclusion Ⅰ, Ⅱ, Ⅴ, Ⅹ, Ⅺ were isolated from Lysimachia L (Primulaceae) for the first time While Ⅵ and Ⅶ were isolated from nature for the first time
