Abstract:The present study was undertaken with an objective to investigate the pharmacognosy of the aerial parts
Artemisia roxburghiana, an ethno-medicinally important plant belonging to sunflower family
(
Asteraceae,)
. Pharmacognostic evaluations were conducted in terms of macroscopic, microscopic, physicochemical and phytochemical analysis according to the WHO and other recommended procedures.
Physiochemical investigation of plant point up that the total ash, acid insoluble ash, water soluble ash, sulphated ash values and loss on drying re 6.26%, 4.0%, 5.46%, 5.66% and 0.30%, respectively. In the present study it is noted that the extractive value of water is similar to the organic solvent investigated. Through the preliminary phytochemical assessment of the crude extracts indicated presence of metabolites like glycosides, flavonoids, phenols, saponins, steroid, which are responsible for pharmacological properties.
Pharmacognostical characters, when stem cut the section of petiole following feature are observe like vascular bundles, xylem, phloem, cambium cell, upper epidermis, lower epidermis & polygonal cells. Pluricellular covering trichomes and clavate trichomes are important diagnostic feature found in A. roxburghiana.
