A new flavanone glucoside, named andrographidine A (1), and five new flavone glucosides, named andrographidines B (2), C (3), D (4), E (5) and F (6), were isolated from the root of Andrographis paniculata.Their structures were determined on the basis of spectral data, especially carbon-13 and proton nuclear magnetic resonance spectra, and chemical derivatization.They have uncommon O-substitution patterns involving 5-, 7-, 8-, 2'-, 3'- and 4'-O-substituents.Keywords - Andrographis paniculata; Acanthaceae; flavone glucoside; flavanone glucoside; andrographidine A; Andrographidine B; 13C-NMR; methylglucopyranoside per-p-bromobenzoate; A-value
