Two new 2'-oxygenated flavones, 5, 2', 6'-trihydroxy-7-methoxyflavone(3)and skullcapflavone I 2'-O-β-D-(4"-E-cinnamyl)glucopyranoside(5), together with three known flavones, 7-O-methylwogonin(1), skullcapflavone I(2)and skullcapflavone I 2'-O-β-D-glucopyranoside(4)were isolated from the whole plant of Andrographis elongata, and the structures were elucidated by FAB-MS and one- and two-dimensional(1D- and 2D)-NMR spectral studies including ^1H-^1H correlation spectroscopy(COSY), heteronuclear single quantum coherence(HSQC), heteronuclear multiple bond connectivity(HMBC) and rotating frame Overhauser enhancement spectroscopy(ROESY) experiments, and chemical studies.
