Book Description
Volume 14 of this series presents three interesting reviews of research on alkaloids. Chapter 1, by Paul L. Schiff, Jr., is a monumental effort, presenting a selective, comprehensive tabular review of research on the bisbenzylisoquinoline alkaloids, with an analysis of the respective alkaloid types. The chapter should serve as a very useful tool for the bench research scientist who is involved in the isolation and elucidation of structures of bisbenzylisoquinoline alkaloids. Moreover, the data in these tables provides the botanical distribution and occurrence (family, genus, species) of the various classes of these alkaloids. The alkaloids are also categorized by their molecular weights and structural types. Chapter 2, by Toh-Seok Kam, is a review of alkaloids derived from Malaysian flora. Malaysia's position near the Equator confers on it a tropical climate characterized by high temperatures, humidity, and rainfall, conditions favorable for plant life that has resulted in a rich flora of about 15,000 species of higher plants. This review concentrates on work published during the past twenty years and where appropriate compares the occurrence of alkaloids with studies of similar plants from countries neighboring to Malaysia, especially Thailand and Indonesia. Chapter 3, by Jie Jack Li, presents a collection of very interesting total syntheses of naturally occurring indole alkaloids where palladium chemistry plays a central role in the syntheses. Five different types of palladium-mediated reactions are treated: (1) oxidative cyclization reactions promoted by palladium (II) species; (2) transmetallation reactions with organoboranes, organostannanes, and organozinc reagents; (3) inter- and intramolecular Heck reactions; (4) reactions with &pgr;-allylpalladium as the intermediate; and (5) reactions using C-N bond formation as the key step for the synthesis.

Book Description
Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.

Book Description
Ranunculales Medicinal Plants: Biodiversity, Chemodiversity and Pharmacotherapy comprehensively covers this order of flowering plants, detailing the phytochemistry, chemotaxonomy, molecular biology, and phylogeny of selected medicinal plants families and genera and their relevance to drug efficacy. The book carries out an exhaustive survey of the literature in order to characterize global trends in the application of flexible technologies. The interrelationship between Chinese species, and between Chinese and non-Chinese species, is inferred through molecular phylogeny and based on nuclear and chloroplast DNA sequencing. The book discusses the conflict between chemotaxonomy and molecular phylogeny in the context of drug discovery and development. Users will find invaluable and holistic coverage on the study of Ranunculales that will make this the go-to pharmaceutical resource. - Describes current perceptions of biodiversity and chemodiversity of Ranunculales - Explains how the conceptual framework of plant pharmacophylogeny benefits the sustainable exploitation of Ranunculales - Details how Ranunculales medicinal plants work from the chemical level upward - Covers how the polypharmacology of Ranunculales compounds might inspire new chemical entity design and development for improved treatment outcomes

Book Description
Carbon (C) is the major component of all cellular life forms such as plants and animals; they utilize C and store it, in different parts of plants viz. Trunks, branches, leaves, reproductive parts (Flowers and Fruits) and roots (Kiran et al.,2011). The C exists in all surviving organisms in the ecosystem or has ever survived.

Book Description
The volume presents current ideas about the systematics and evolution of the Ranunculiflorae and most of its constituent families. A strong effort has been made to integrate DNA and morphological, anatomical, etc. evidence, and new ideas about the origin and phylogeny of the entire group as well as the Berberidaceae, Lardizabalaceae, Ranunculaceae, and Papaveraceae are arrived at.

Book Description
"Atlas of Woody Plants in China: Distribution and Climate” documents the spatially-explicit county-level distribution of all 11,405 woody plants in China, together with life form information for most species. It also provides climate information for each species, with the county-level average and range of 12 climatic indices and of vegetation net primary productivity. It is the first and largest comprehensive atlas in the world for the distribution of China’s plants and was compiled on the basis of almost all related literature published throughout China. The atlas should serve as an indispensable handbook for all those who are interested in the plants, ecology, geography, environment, horticulture, and silviculture of China and East Asia. Dr. Jingyun Fang is a Cheung Kong Professor at the Department of Ecology, Peking University, China. Dr. Zhiheng Wang and Dr. Zhiyao Tang are both ecologists working at the same institute.

Book Description
This book offers a broad summary of the wild plants and their usage, as well as the growing interest in ethnopharmacology research. The book comprises of important issues such as diversity of wild plants with emphasis on medicinal and food plants, threats to wild plants and traditional ethnobotanical knowledge, their uses in skin diseases, snake-bites, in cosmeceuticals, etc. Moreover, the ethnopharmacological relevance of wild plants in Latin America has been discussed. The chapters include a wide range of case studies, giving updated evidence on the importance of their wild plant resources from different countries including Peru, Nepal, Bangladesh, India, Pakistan, Brazil. In addition, some specific species are used to explain their potential properties, as well as the dangers of their use without guidance of trained natural healers. The book discusses traditional usage and properties of wild plants and is entirely different from other related publications and useful for the researchers working in the areas of conservation biology, botany, ethnobiology, ethnopharmacology, policymakers, etc.
