A rapid and sensitive silver ion high-performance liquid chromatographic (Ag[I]-HPLC) method is developed for the simultaneous determination of the biologically active diterpenoids andrographolide, 14-deoxy-11,12-didehydroandrographolide, 14-deoxyandrographolide, and neoandrographolide in Andrographis paniculata Nees. HPLC is carried out for determining andrographolide and its derivatives with ...
