[Phytochemical investigation on Lysimachia fortunei].
OBJECTIVE
To investigate the chemical constituents in the ethyl acerate extract of Lysimachia fortunei.


METHODS
The compounds were isolated by silica gel chromatography, and their structures were elucidated by NMR data and references.


RESULTS
Nine natural constituents were isolated, and their structures were identified as 9, 19-cyclolanost-24-en-3-one (1), 24-ethyl-5alpha-cholesta-7, 22(E)-dien-3-one (2), 1-pentatriacontanol (3), beta-stigmasterol (4), 24-ethyl-5alpha-cholesta-7, 22(E)-dien-3beta-ol (5), palmitic acid (6), isorhamnetin (7), kaempferol (8) and quercetin (9) respectively.


CONCLUSIONS
All compounds mentioned above were isolated from this plant for the first time, and compound 1, 2 and 5 were obtained from the genus for the first time.
