Objective To investigate the pharmacognostic characters of important medicinal plant, Artemisia parviflora (A. parviflora) Roxb. Methods The pharmacognostic studies were carried out in terms of macroscopical, microscopical characters, physicochemical parameters of A. parviflora. Samples of different plant parts were fixed with formalin, acetic acid and ethyl alcohol (FAA), sectioned with rotary microtome and studied under microscope. Results Some of the diagnostic features of the leaves and stems are the presence of amphistomatic epidermis, cyclocytic stomata, and collateral vascular bundles. Macroscopic study showed basal and lower stem leaves cuneate, oblong-obovate to flabellate, coarsely dentate to incised-dentate at the apex; middle and upper stem leaves mostly basally auriculate, palmatifid to deeply palmatisect or irregularly incised laciniate into linear to narrow lanceolate, acute segments. Further, ash and extractive values were calculated as per WHO guidelines. The preliminary phytochemical screening showed the presence of alkaloids, sterols/terpenoids, flavonoids, tannins, phenols and coumarins. Conclusion Various pharmacognostical characters were observed in study which can help in identification and standardization of A. parviflora.
