RESUMEN
Herbal medicines are natural products and their phytoconstitutents vary depending on time and region, processing and storage. Variations in the collection, processing or storage of an herb could impact its efficacy profile. Since prior knowledge regarding appropriate collection and usage of most medicinal plants exists in tradition, it can be used as a guide to quality standardization. The present study is aimed to carry out research work to evaluate Pharmacognostic investigation on Root & Leaf extract of Abutilon indicum. From the literature study it is found that a very little work is done on root & leaf part of plant for setting standardization limits. So, our aim is to find out again various standardization limits according WHO guideline like macroscopic & microscopic study, to find out LOD, ash values, extractive values etc. for root & leaf part of drug with a view to control the quality of crude drug.
RESUMEN
Objective: To evaluate the pharmacognostic parameters of the leaves of Abutilon indicum (Linn.) Sweet which will assist in standardization, quality assurance, purity and sample identification of the species. Methods: The pharmacognostic studies were carried out in terms of organoleptic, microscopic, powder microscopic, leaf constants and fluorescence analysis. Results:Macroscopic study showed that the leaf shape -cordate, Size -2-4 cm long, Colour - Green, Odour -Characteristic, Taste -Characteristic, Surface - Smooth, Apex -Acute to acuminate, Lamina-Simple, Cordate, Reticulate, Dentate, Margin-Crenate-Dentate. The microscopic features of leaves were observed as covering trichomes, glandular trichome, vascular bundles, crystals, stomata ,mucilage secretory cells adaxial epidermis, palisade mesophyll, spongy mesophyll and lateral vein. Further the study was evaluated leaf constants, powder microscopy and fluorescence study of leaf powder. Conclusion: Various pharmacognostic characters observed in this study help in the identification and standardization of Abutilon indicum (Linn.) Sweet.
