Acylated 5,7,2',6'-oxygenated flavone glycosides from Andrographis alata.
Five acylated 5,7,2',6'-oxygenated flavone glycosides along with the known 5,2',6'-trihydroxy-7-methoxyflavone-2'-O-beta-d-glucopyranoside have been isolated from the whole plant of Andrographis alata. The structures of the compounds were established from spectral (mainly 1D and 2D NMR) and chemical studies.
