Two New Alkaloids from the Roots of Baphicacanthus cusia

摘要

Phytochemical investigation of the root of Baphicacanthus cusia (NEES) BREMEK afforded two new alkaloids, baphicacanthin A ( 1 ) and baphicacanthin B ( 2 ), along with 28 known compounds. The chemical structures of these compounds were elucidated on the basis of one and two dimensional (1D/2D)-NMR and high resolution (HR)-MS spectral evidence.
