Powdered Crude Drug Microscopy of Leaves and Bark

Powdered Crude Drug Microscopy of Leaves and Bark is a complete resource for the microscopic identification and authentication of herbal drugs. Various microscopic techniques, structural and cellular features of herbs are examined for the determination of botanical origin. This method is useful for identifying species with similar morphological characters. Today, there are a variety of methods available to authenticate herbal drugs, ranging from simple morphological examination to physical and chemical analysis, and DNA molecular biology. Due to cost, powder microscopy is the most practical method for primary authentication. Botanical microscopy is a unique, valuable, rapid and cost effective assessment tool, and plays an important role in the authentication and assessment of medicinal plants. This book is an essential resource for students and researchers involved in the study of plants and natural products. Provides fundamental understanding of the macroscopic and microscopic characteristics of crude drugsIncludes specific characteristics and sub-features for identifying barks, including stone cells, calcium oxalate crystals, starch grains, medullary rays, fibres, sclereids, cork, isolated oil cells, tubular lactiferous canals, phloem parenchyma, masses, rhytidoma, parenchyma, and secretory canalsIncludes specific characteristics for identifying leaves, such as epidermis, stomata, trichomes, calcium oxalate crystals, fibres, cell contents, cystoliths, lamina, starch grains, tracheids, lactiferous canals and xylem vesselsProvides photographs of the macroscopy and microscopical characters of the crude drugFeatures a standard operating protocol for preparation of slides to observe general as well as distin-guishing microscopical characters of barks and leaves for industrial grounded and lab samples INDICE: 1.
