This book, ''Phytochemicals of Pteridophytes: Occurrence, Structures, and Biological Activity'', explores the chemical constituents of pteridophytes (lycophytes and ferns), emphasizing their occurrence, structures, and biological functions. It covers a wide range of phytochemicals, including aromatic compounds (e.g., acylphloroglucinols, flavonoids, lignans, selaginellins) and isoprenoids (e.g., monoterpenoids, norisoprenoids, sesquiterpenoids, diterpenoids, and steroids). The book examine...

Simon Gibbons embarks on a detailed and groundbreaking study in this book, examining the profound influence of Harold Rosen, a pivotal figure who transformed English education in the latter half of the twentieth century. Gibbons offers the first comprehensive analysis of Rosen’s revolutionary contributions to progressive English teaching methodologies that continue to resonate in classrooms worldwide.Drawing on extensive research, including previously unpublished writings and inter...

This volume explores the Diels–Alder reaction, a cornerstone of organic chemistry, tracing its evolution from a classical synthesis tool to a versatile platform for constructing complex molecular architectures. It highlights the reactions historical significance, methodological advancements, and pivotal role in natural product synthesis. From its discovery in the early 20th century, the Diels–Alder reaction revolutionized organic synthesis by enabling efficient formation of six-membered ri...

This volume explores the biologically active compounds found in 21 high-value medicinal and aromatic plant species native to Malaysia, emphasizing their phytochemical diversity and biological activities.Several of these plants, including Eurycoma longifolia, Andrographis paniculata, Morinda citrifolia, Centella asiatica, and Moringa pleifera, have been prioritized as high-priority herbal products under Malaysia's National Key Economic Area in th...

The book reviews the natural product chemistry of Australian rainforest plants, with a particular focus on their fascinating phylogenetic relationships. It discusses the unique flora of Australia, which is of Gondwanan origin, and how this has led to a diverse range of natural products. The text explores the chemical constituents of various plant groups, including those of gymnosperms, basal angiosperms, magnoliids, monocots, and eudicots, with an emphasis on the Australian rainforest spec...

Pharmacognosy, the science of nature-derived drugs, pharmaceuticals and poisons, played a crucial role in the development of modern medicine, and now has an equally important place in healthcare all over the world. This wide scope ranges from traditional medicine systems and herbal and nutritional therapies, the preparation and use of highly standardised and clinically tested herbal medicines, to the production of potent drugs used only in a purified form. Natural sources mainly focus on p...

The rich biodiversity of Borneo provides many useful plants for medicinal purposes. Written by experts in the field, Medicinal Plants of Borneo provides a guide and introduction to the medicinal plants from Borneo used traditionally as well as plants whose medicinal uses have been recently discovered. These include anti-HIV plants – such as Calophyllum lanigerum (calanolide A) – and anti-cancer plants – such as Aglaia foveolata (silvestrol). The book also...

This book reviews the distribution, chemistry, and molecular bioactivity of tiglianes from the very beginning of the studies on these diterpenoids. It provides a summary of their clinical and toxicological literature mostly in its more recent and controversial aspects, while critically analyzing various proposals for their biosynthesis.

This book discusses the phytochemistry of bryophytes, with a particular focus on their biologically active natural products and their potential applications in medicine, cosmetics, and as foods. Bryophytes, which include the mosses, liverworts, and hornworts, produce a plethora of terpenoids, phenolic compounds, and polyketides that exhibit diverse pharmacological activities, including anti-inflammatory, antiobesity, antioxidant, cytotoxic, and muscle-relaxant effects. The volume also expl...

This volume presents three chapters discussing a range of topics. Chapter 1 deals with the development of efficient methods for compound dereplication that have been critical in the re-emergence of research on natural products as a source of new drug leads. It describes the main methods of dereplication, which rely on the combined use of large natural product databases and spectral libraries, alongside the information obtained from chromatographic, UV-Vis, MS, and NMR spectroscopic analyse...

English and Its Teachers offers a historical overview of the development of secondary English teaching in schools over the past 50 years. Initially charting the rise of a new progressive approach in the 1960s, the book then considers the implications for the subject and its teachers of three decades of central policy intervention. Throughout, document and interview data are combined to construct a narrative that details the fascinating and, at times, turbulent history.The ...

Studies of comparative classroom practice in the teaching of secondary English are limited, especially when it comes to exploration of the day-to-day practice of English teachers in the secondary classroom. This book presents a case study analysis of secondary classroom practice in three countries: Canada, England and Scotland. Each country has had different degrees of state involvement within the secondary English curriculum over the last twenty years. England has had the highest degree o...
