Written by experienced authors, this book presents numerous natural everyday products with a high range of structural diversity. Twenty natural products have been arranged in five sections, describing three alkaloids, five colored compounds, three carbohydrates and glycosides, seven terpenoids, and two aromatic compounds. Adopting a highly didactical approach, each chapter features a uniform structure: Background, in-depth information about isolation processes and structural characterization as well as a Q&A section at the end. Alongside the theoretical information many practical hints for the laboratory work are also included. A comprehensive overview of UV-, IR- and NMR-spectroscopy as well as mass-spectrometry for every exemplified compound is provided and the understanding of these methods is supported by concluding questions and exercises. Educating and entertaining, this full-color textbook turns the learning process into a real pleasure, not only for students in natural products chemistry but also experienced professionals.

Analytik von Naturstoffen, die jeder kennt: Die Autoren dieses Bandes beschränken sich nicht auf die nüchterne Abhandlung von Daten und Verfahren, sondern erzählen die wahrhaft inspirierenden Geschichten jedes ihrer Moleküle. Dabei ist der rein methodische Teil so ausführlich und exakt beschrieben, dass der Band hervorragend für Lehre und Studium geeignet ist. Übungsaufgaben mit Lösungen und das attraktive Layout machen das Buch zu einem Muss für jeden Organiker und Spektroskopiker und die, die es werden wollen.
Few of us, as we live our daily lives, think of eventually writing a memoir, believing probably that what we are doing, or how we are living, is not worth recording for posterity or for those around us. So it was with Dieter Dubberke, who scoffed at the idea when it was first presented to him by his wife and one or two others. Only reluctantly did he begin the project, and even then it was with the intention that it would be only for his children and their families, and maybe--just maybe--for a very few others. However as his focus sharpened, and as he remembered an increasing number of details, he began to see a greater value in recounting his life--how he had conducted himself and what he had learned, and how he came to honor and to embrace certain principles which might be worth passing on to others who could benefit from what he had seen and experienced and done. As a little boy, he and his mother dodged bullets while escaping from the easternmost part of Germany just ahead of the advancing Russians in the closing days of World War II. With his mother and brother he finally made it to the West, before the Iron Curtain would have trapped them permanently behind its impenetrable barrier. Even so, life wasn't easy there after the war, and survival was a matter of day-to-day, hand-to-mouth existence. Food was scarce, and fuel for heat during the bitter winters was something which had to be scrambled for, a few stray lumps of coal dropped in the road and fished from icy potholes with frozen hands. The lessons learned in how to survive were hard ones, the kind which were burned indelibly into him but which served him well in later years. He was blessed just to survive the war and its aftermath. However he received another stroke of that same good fortune which had followed him when he had a chance at age thirteen to come to America, where he was adopted by his maternal uncle, who had emigrated to the US years before. A whole new life opened up for him, and from the beginning he was determined to appreciate it and make the best of it. Education in an American high school and service in the US Army thoroughly Americanized him and gave him a deep and abiding love for this country and for the opportunities it offers to those who recognize them and seize them. Seize them he did. The same work ethic which helped him survive the rigors of post-war Germany was now put to use in establishing a family and building a career. He learned the retail food industry in the Safeway organization. His love of the outdoors and a rural way of life led him to the small and artsy town of Ojai, California, where he became a store manager, catering to the tastes of the creative avant-garde while never neglecting the needs of the everyday ordinary shopper. However it was when he ventured out on his own, in Mariposa, California, that he found the chance to become completely his own man and to develop to the fullest his true entrepreneurial talents and abilities. Starting with one small store, he opened a major supermarket which utilized the newest in marketing techniques and provided to the small community a much wider range of choice than it had previously known. Then came another business, and another. However simply to make this a tale of some inevitable expansion would be all too familiar and mundane. This kind of growth has remained but a part of the story of his success, one which can only be told and fully appreciated in light of his accomplishment as a person. Everything he learned in those early days of hardship and deprivation somehow gradually came together over the years to elevate both his mind and his spirit, to produce in him a broader and higher way of thinking, and a more expansive outlook. He quickly but quietly became a respected leader within his community. Clear thinking, dispassionate reasoning and the ability to rise above personal feelings all combined to make him the kind of person whom people sought
Memoirs cover the life of an immigrant from his youth in Berlin, Germany, experiencing World War II to his later immigration to the United States and service in the US Army and Special Forces, the Green Berets. The book covers his experiences as a member of the "Jungvolk" and Hitler Youth during Air Raids in Berlin, evacuation of the family without a father to the East, life on a Trek from the Polish border back to Berlin and combat against the Russian Army. Following the loss of WWII it describes life under Soviet Occupation, bare survival and later flight to freedom from East Germany to West Germany. Reaching the American Sector in West Germany and processing through a refugee camp, his family was reunited with their father a former member of the German Air Force, who had been a POW. Having lost all of their personal belongings as a result of the war, the author was obligated to leave school to support the family. Unable to find adequate employment he eventually joined a para-military US Army unit, which later on gave him the opportunity to emigrate to the United States. Once in the States, he saw the opportunities the military offered to "Be all you can be", as the Army once promised in their recruiting efforts. He joined the Army and following his enlisted career advanced through his determination to become a commissioned officer, qualifying himself through extraordinary training in the field of Ranger, Airborne, Jungle Warfare and finally the US Army Special Forces, the so-called Green Berets. He had the opportunity to serve several tours in Germany, as well as tours in the Republic of South Vietnam during 1967-1968 and the Republic of Korea. Following a 20-year career in the military, the decorated combat veteran retired at Fort Bragg, NC and finally moved with his wife and two children to Hagerstown, MD.
Dieter Schlesak's haunting novel The Druggist of Auschwitz—beautifully translated from the German by John Hargraves—is a frighteningly vivid portrayal of the Holocaust as seen through the eyes of criminal and victim alike. Adam, known as "the last Jew of Schäßburg," recounts with disturbing clarity his imprisonment at the infamous Auschwitz concentration camp. Through Adam's fictional narrative and excerpts of actual testimony from the Frankfurt Auschwitz Trial of 1963–65, we come to learn of the true-life story of Dr. Victor Capesius, who, despite strong friendships with Jews before the war, quickly aided in and profited from their tragedy once the Nazis came to power. Interspersed with historical research and the author's face-to-face interviews with survivors, the novel follows Capesius from his assignment as the "sorter" of new arrivals at Auschwitz—deciding who will go directly to the gas chamber and who will be used for labor—through his life of lavish wealth after the war to his arrest and eventual trial. Schlesak's seamless incorporation of factual data and testimony—woven into Adam's dreamlike remembrance of a world turned upside down—makes The Druggist of Auschwitz a vital and unique addition to our understanding of the Holocaust.
