Chemical constituents of andrographis paniculata (Burm.f.) nees
Chemical investigation of the dichloromethane extracts of Andrographis paniculata (Burm.f.) Nees led to the isolation of andrographolide (1), 14-deoxyandrographolide (2), 14-deoxy-12-hydroxyandrographolide (3), a mixture of β-sitosterol (4a) and stigmasterol (4b) in a 3:1 ratio, and chlorophyll a (5...
