A flavone and an unusual 23-carbon terpenoid from Andrographis paniculata.
Phytochemical investigation of the roots and aerial parts of Andrographis paniculata Nees yielded a new flavone, 5-hydroxy-7,2',6'-trimethoxyflavone and an unusual 23-carbon terpenoid, 14-deoxy-15-isopropylidene-11,12-didehydroandrographolide together with five known flavonoids and four known diterpenoids. The structures of these compounds were determined on the basis of spectral and chemical studies.
