Pharmacognosy of the floral and vegetative parts ofArtemisia scoparia Waldst, and Kit. (‘Dona’), a bitter aromatic herb used in the indigenous systems of medicine, was carried out with a view to lay down standards for the genuine drug. The parameters studied include anatomical and microscopic details of the different parts; certain physico-chemical constants such as ash values, percentage of tannins, and successive extractives; as well as qualitative detection of the main chemical constitutents in the various extractives. Thin layer chromatography and fluorescence tests of drug powder were also carried out. Presence of casparian strips in the endodermis, resin canals, four-to eight-celled characteristic glandular hairs on the corolla and absence of pappus are some of the diagnostic features of the drug.
