| Popis: | 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. |
