  ABSTRACT: Physicochemical parameters of roots of three Plumbago species, Plumbago capensis , P. rosea and P. zeylanica belonging to Plumbaginaceae were analyzed. Microbial contamination, aflatoxins, pesticide residue and heavy metal content were also determined. Attempt has also been made to estimate the biologically active chemical plumbagin present in them and the data compared. The study ensures that the quality control parameters do help in the proper standardization of the crude drugs in drug development process for global acceptance.

  ABSTRACT: Two flavonoids and two carboxylic acids have been isolated from the ethyl acetate extract of the roots. The structures of these compounds have been established as myricetin-3,3',5',7-tetra methyl ether 1. ampelopsin-3',4',5',7-tetramethyl ether 2, plumbagic acid 3 and roseanoic acid 4 on the basis of UV, IR, H-1 and C-13 NMR and mass spectrum studies. The two carboxylic acids 3 and 4 arc reported here for the first time. Compounds 1 and 2 are the first report from the genus plumbago.
