The work deals with Pharmacognostic, physicochemical and preliminary phytochemical analysis of Hibiscus cannabinus L., (Malvaceae). The macroscopic and microscopic characteristics were observed namely physical constant values, ash values, and micro-chemical analysis. The presence of lignified cells, pericyclic fibers, stone cells, cuticles, calcium oxalate crystal, as seen in the powders of leaves. Physical constants like foreign organic matter, moisture content, ash content, acid-insoluble ash and water-soluble ash extractive values were determined the extracts shows presence of steroids, flavonoids, carbohydrates, alkaloid, glycosides, phenols, and tannins by phytochemical screening. The above study will highlighted characterize the pharmacognotical, physicochemical and preliminary phytochemical parameters of Hibiscus cannabinus Linn.
