Abstract
OBJECTIVE: To study the chemical constituents from Lysimachia circaeoides. METHODS: The column chromatographic techniques were applied to isolate the constituents. EI-MS and NMR were used to identify the structures. RESULTS: Eight compounds were isolated and identified from the extract of L. circaeoides and their structures were elucidated as kaempferol (1), beta-daucosterol (2), beta-sitosterol (3), quercetin (4), luteolin (5), quercetin-3-O-beta-D-galactoside (6), kaempferol-3-O-beta-D-glucoside (7) and rutin (8). CONCLUSION: Compounds 1 - 8 are isolated from this plant for the first time.
