Book Description
The plant's cells and their several specialized working subunits are examined in addition to chemical traits like color, scent, and the hormonal effects that turn leaves toward the light and allow other adaptations to the surroundings. And the major processes driven by chemical changes over time that together are the life cycle of the plant are considered."--BOOK JACKET.

Book Description
Powdered Crude Drug Microscopy of Leaves and Barks investigates various microscopic techniques used in the examination of structural and cellular features in order to determine their botanical origin. These methods are useful in identifying species with similar morphological characters. Today, there is 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, as well as professionals in industries manufacturing plant-based products for use during quality control and assurance steps. Provides a fundamental understanding of the macroscopic and microscopic characteristics of crude drugs, including photographs of herbs in their raw and powder forms. Presents specific characteristics and sub-features for identifying barks and leaves, 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 canals. Includes 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 vessels. Demonstrates how the specificity of characteristics for a particular bark or leaf in powder form can lead to its authentication. Features standard operating protocols for preparation of slides and lab samples using industrially operated grinders to observe general as well as distinguishing microscopical characters of barks and leaves.

Book Description
Recent major shifts in global health care management policy have been instrumental in renewing interest in herbal medicine. However, literature on the development of products from herbs is often scattered and narrow in scope. Herbal Bioactives and Food Fortification: Extraction and Formulation provides information on all aspects of the extraction of biological actives from plants and the development of dietary supplements and fortified food using herbal extracts. The book begins with a brief survey of the use of herbs in different civilizations and traces the evolution of herbal medicine, including the emergence of nutraceuticals from the discipline of ethnopharmacology and the Alma Ata Declaration of 1978. It moves on to describe various aspects of the extraction process, including selection of plant species, quality control of raw materials, the comminution of herbs, and the selection of solvents. It also describes the optimization of extraction in relation to response surface methodology before describing uses of herbal extracts in food supplements and fortified foods. With special attention paid to stability analysis and the masking of tastes, the book gives an overview of the formulation of various types of tablets, capsules, and syrups using herbal extracts. It also describes the benefits of foods fortified with herbal extracts such as soups, yogurt, sauces, mayonnaise, pickles, chutneys, jams, jellies, marmalades, cheese, margarine, sausages, bread, and biscuits, as well as some beverages. Herbal Bioactives and Food Fortification covers the fundamental steps in herbal extraction and processing in a single volume. It explains how to choose, optimize, analyze, and use extracts for fortification, making it an excellent source for nutraceutical researchers and practitioners in science and industry.

Book Description
Plant Cell Organelles contains the proceedings of the Phytochemical Group Symposium held in London on April 10-12, 1967. Contributors explore most of the ideas concerning the structure, biochemistry, and function of the nuclei, chloroplasts, mitochondria, vacuoles, and other organelles of plant cells. This book is organized into 13 chapters and begins with an overview of the enzymology of plant cell organelles and the localization of enzymes using cytochemical techniques. The text then discusses the structure of the nuclear envelope, chromosomes, and nucleolus, along with chromosome sequestration and replication. The next chapters focus on the structure and function of the mitochondria of higher plant cells, biogenesis in yeast, carbon pathways, and energy transfer function. The book also considers the chloroplast, the endoplasmic reticulum, the Golgi bodies, and the microtubules. The final chapters discuss protein synthesis in cell organelles; polysomes in plant tissues; and lysosomes and spherosomes in plant cells. This book is a valuable source of information for postgraduate workers, although much of the material could be used in undergraduate courses.
