Pharmacognostic 8 Phytochemical Evaluation of Bryophyllum Pinnatum Leaves

Abstract

In the present study leaves of Bryophyllum Pinnatum (life plant) were subjected to pharmacognostical studies such as determination of epidermal cell, parenchyma cell, cambium, xylem, phloem, stomata. Quantitative microscopy including stomatal number, stomatal index, vein islet and vein terminations were determined by using fresh leaves of the plant and results were observed. Physicochemical studies such as ash values, extractive values of plant part were carried out to confirm the identity of plant and to ascertain the quality and purity of the drug. Ash values such as total ash, acid insoluble ash, water soluble ash and sulphated ash of the plant were determined and recorded. Extractive values such as alcohol soluble extractives and water soluble extractive values were determined. These parameters may be useful for the identification and authentification of the plant for the future investigators.
