Abstract To study the bioactive constituents from Andrographis paniculata, two compounds were isolated and purified by column chromatography on AB-8 macroporous adsorption resin and polyamide. Their structures were determined by various spectroscopic methods, including UV, FABMS, 1H-NMR, 13C-NMR, DQFCOSY, TOCSY, HMQC, HMBC, and NOESY. The 1H-NMR and 13C-NMR signals of the two compounds were assigned. The structures of the two compounds were elucidated as 5,4′-dihydroxy-7-methoxyflavone-6-yl-?-D-glucopyranoside and 5,4′-dihydroxy-7-methoxyflavone- 8-yl-?-D-glucopyranoside, respectively.
