[Phytochemical investigation on Lysimachia fortunei].

ABSTRACT

OBJECTIVE: To investigate the chemical constituents in the ethyl acerate extract of Lysimachia fortunei. METHOD: The compounds were isolated by silica gel chromatography, and their structures were elucidated by NMR data and references. RESULT: 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. CONCLUSION: 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.
