Abstract: Two new flavonoids, 5,7,8,2'-tetramethoxyflavanone 1 and 2'-hydroxy-2,3,4'-trimethoxychalcone 3, together with three known flavones, 5-hydroxy-7-methoxyflavone 2, 5,2',6'-trihydroxy-7-methoxyflavone 4 and 5,7,2',6'-tetra­hydroxy­flavone 5 have been isolated from the whole plant of Andrographis macrobotrys. The structures of the new compounds 1 and 3 have been established using extensive 2D NMR and ESI-MS/MS studies.
