Comparative Morphological, Microscopical Study of Ocimum Species: Research Article

ABSTRACTNow a days, increasing use of herbal products needs to study the medicinal plants by more appropriate study in relation to maintain its quality standards. In this paper, the literature and the published work on comparative Pharmacognostical study of Ocimum species. Aim of present study is to establish comparative standards for different species of Ocimum, to collect and comparatively evaluate morphological microscoscopical characters of different species of Ocimum, to comparatively evaluate micro chemical parameters of different species, to develop comparative standards to differentiate species of Ocimum. The T.S of leaf shows the presence of epidermis, parenchymatous cells, collateral vascular bundle, lateral vein, glandular trichomes which are peltate type and sessile. Powder microscopy of the leaf shows the presence of epidermal peelings and multicellular unbranched trichomes.  In present study, the authenticated plants were studied for Pharmacognostical Evaluations including study of Macroscopic Evaluations, Microscopic Evaluations. The macroscopic of leaves and steam of each species was studied by observing the organoleptic characters such as colour, size, texture and surface characteristics.
