Over the past decade there has been a resurgence of interest in growing fruit and vegetables in the garden and on the allotment. Part of the driving force behind this is an increased awareness of the health benefits that can be derived from fruit and vegetables in the diet. The 'five helpings a day' dictum reflects the correlation between a regular consumption of fruit and vegetables and a reduced incidence of, for example, cardiovascular disease and some cancers. Growing your own vegetables provides the opportunity to harvest them at their peak, to minimize the time for post-harvest deterioration prior to consumption and to reduce their 'food miles'. It also provides an opportunity to grow interesting and less common cultivars. The combination of economic advantages and recreational factors add to the pleasure of growing fruit and vegetables. This book covers the natural products that have been identified in common 'home-grown' fruit and vegetables and which contribute to their organoleptic and beneficial properties. Over the last fifty years the immense advances in separation methods and spectroscopic techniques for structure elucidation have led to the identification of a wide range of natural products in fruit and vegetables. Not only have many of their beneficial properties been recognized but also their ecological roles in the development of plants have been identified. The functional role of many of these natural products is to mediate the balance between an organism and its environment in terms of microbial, herbivore or plant to plant interactions. The book is aimed at readers with a chemical background who wish to know a little more about the natural products that they are eating, their beneficial effects, and the roles that these compounds have in nature. Developments in the understanding of the ecological and beneficial chemistry of fruit and vegetables have made the exploration of their chemical diversity a fascinating and expanding area of natural product chemistry and readers will obtain some 'taste' for this chemistry from the book. It develops in more detail the relevant sections from the earlier RSC book 'Chemistry in the Garden'. The book begins with an outline of the major groups of compound that are found in fruit and vegetables. This is followed by a description of aspects of environmental chemistry that contribute to the successful cultivation of these crops. Subsequent chapters deal with individual plants which are grouped in terms of the part of the plant, roots, bulbs and stems, leaves, seeds, that are used for food. The final chapters deal with fruit and herbs. The epilogue considers some general aspects of ecological chemistry and climatic stress which may, in the future, affect the growth of fruit and vegetables in the garden particularly in the context of potential climate changes. The book concludes with a section on further reading, a glossary of terms used in plant chemistry and a list of the common fruit and vegetables grouped in their plant families.
Why are some plants so important to humans? The chemistry of the plants has a lot to do with it! The plant world offers a fascinating way to explore basic chemistry concepts. The spectacular variety of colors, fragrances and other characteristics of plants are driven by the seemingly subtle differences in the structure and properties of organic compounds. Well-known flowers, like daffodils and narcissus, are examples of plants that provide ample perfumes, pigments and poisons as part of their intricate and fascinating chemistry. This second edition retains it accessibility, expanding on the first edition and combining scientific concepts with colorful pictures and stories in simple, clear language. Readers will find introductory information on some chemistry and plant biology. This prepares them for the more complex chemical structures that compose plant substances, many of them of vital importance to humans. The final chapter has been expanded, in particular the sections on medicinal plants and on genetic modification. The end-of chapter references have been thoroughly updated with articles, books, and relevant websites that illustrate the topics discussed. Dr Margareta Sequin, an organic chemist and plant enthusiast, has taught popular undergraduate college level courses on plant chemistry to non-chemistry majors and has led numerous field seminars for the general public. The comments and questions from these audiences and the topics that especially captured people’s interest have greatly shaped this book. The Chemistry of Plants addresses an audience with little previous chemistry knowledge, but will appeal to the expert reader looking for an understanding of more complex plant compounds. It can be used both as a text to introduce organic chemistry as it relates to plants and as a text of reference for more advanced readers.

Hand cream, detergent, shower gel, toothpaste, toilet cleaner, air freshener, lipstick, perfume, low-fat spread, painkiller, diet drink, insect repellent... hundreds of everyday products that make our lives so much better than those of our forebears. And yet most of us know little about the ingredients they contain and why they deliver the benefits we enjoy. Some people find it worrying when they examine the list of ingredients on a packaging label, because all they read may be unintelligible names or E numbers. It appears to be just chemicals, chemicals, chemicals. The aim of this book is to examine the ingredients more closely and explain the reasons for their being used. Start reading and stop worrying. Chemistry at Home has been written by award-winning popular science writer and chemist, John Emsley, using non-technical language. The book has 12 chapters, each devoted to the kinds of products we are likely to find around the home, including in the garage and the garden shed. Chemistry at Home also includes a glossary which gives more technical information about the molecules mentioned in the book.
For many years, Leonard A. Ford, formerly Chairman of the Division of Science and Mathematics at Mankato State College, Minnesota, devised "chemical magic" shows for a series of college science fairs. In response to many requests, he compiled a volume of over 100 novel demonstrations from those shows. The book soon became one of the most widely used manuals in the field. Its tricks, mystifying and often spectacular, were designed not only to amuse and entertain an audience but to stimulate an interest in scientific principles. Now, with this revised and enlarged republication of Dr. Ford's classic guide, students at both high school and college levels can learn to perform a wide variety of entertaining and educational chemical magic. Here is a dazzling array of stunts and demonstrations dealing with gas liberation, color changes, fires and combustion, smoke and vapors, polymerization, specific gravity, crystallization and precipitation, and many other chemical processes. Professor Ford provides clear and careful explanations for creating cold fire, a disappearing flame and dust explosions; dissolving a glass in water; turning water to milk and back again to water; producing mysterious balloons, heavy air, and magical eggs; and carrying out scores of other intriguing "tricks" with materials available in almost any school laboratory, supply house, or home. Training and experience in handling chemicals are required for the performance of these demonstrations. Dr. Ford outlines directions and safety precautions for each trick. In addition, he supplies helpful suggestions for a line of "patter" to use during performances. Newly revised and updated by Professor E. Winston Grundmeier, this absorbing and unusual book will be welcomed by science educators at the high school and college levels as well as by sponsors of youth and church groups, service clubs, science fairs, and other organizations.
Half a million years ago our ancestors learned to make fire from scratch. They crafted intricate tools from stone and brewed mind-altering elixirs from honey. Their descendants transformed clay into pottery, wool into clothing, and ashes into cleansers. In ceramic crucibles they won metal from rock, the metals lead to colored glazes and glass. Buildings of brick and mortar enshrined books of parchment and paper. Kings and queens demanded ever more colorful clothing and accessories in order to out-class clod-hoppers and call-girls. Kingdoms rose and fell by the power of saltpeter, sulfur, and charcoal. And the demands of everyday folk for glass and paper and soap stimulated the first round of chemical industrialization. From sulfuric acid to sodium carbonate. From aniline dyes to analgesic drugs. From blasting powder to fertilizers and plastics. In a phrase, From Caveman to Chemist. Your guides on this journey are the four alchemical elements; Fire, Earth, Air and Water. These archetypical characters deliver first-hand accounts of the births of their respective technologies. The spirit of Fire, for example, was born in the first creature to cultivate the flame. This spirit passed from one person to another, from one generation to another, from one millennium to another, arriving at last in the pages of this book. The spirit of Earth taught folks to make tools of stone, the spirit of Air imparted knowledge of units and the spirit of Water began with the invention of spirits. Having traveled the world from age to age, who can say where they will find their next home? Perhaps they will find one in you.
