Abstract:
OBJECTIVETo study the chemical constituents from Lobelia chinensis.
METHODThe constituents were extracted with 95% EtOH, partitioned with different solvents, and isolated and purified by silica gel column chromatography and crystallization, their structures were elucidated by physico-chemical properties and spectroscopic data.
RESULTSeven compounds were isolated from the titled plant. They were identified as 5-hydroxy-4'-methoxyflavone-7-O-rutinoside (1), n-butyl-O-beta-D-fructopyranoside (2), 5,7-dimethoxycoumarin (3), cirsiumaldehyde (4), diosmetin (5), 5-hydroxymethyl-2-furancarboxaldehyde (6), and 6-hydroxy-7-methoxycoumarin (7).
CONCLUSIONCompounds 2-4, 6, and 7 were obtained from the titled plant for the first time.
