[Chemical constituents of Lysimachia paridiformis].

To study the chemical constituents from Lysimachia paridiformis.The column chromatographic techniques were applied to isolate the chemical constituents of Lysimachia paridiformis. EI-MS and NMR were used to identify the structures.Seven compounds were isolated and identified from the extract of L. paridiformis, and their structures were elucidated as stigmasterol (1), oleanolic aicd (2), beta-amyrin (3), quercetin (4), luteolin (5), quercetin-3-O-beta-D-galactoside (6) and beta-daucosterol (7).Compound 1 -7 are isolated from this plant for the first time.
