Flavones from the stem of Andrographis paniculata Nees.
Chemical investigation of Andrographis paniculata Nees (Acanthaceae) resulted in the isolation of three flavones identified as 5-hydroxy-7,8,2'-trimethoxyflavone 1, 5-hydroxy-7,8-dimethoxyflavone 2 and 5-hydroxy-7,8,2',5'-tetramethoxyflavone 3 from the hexane, methanol and chloroform extracts of the root and stem.
