This book was released on 2013-11-26 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artemisinin, a sesquiterpene lactone originally extracted from the medicinal plant Artemisia annua L., is an effective antimalarial agent, particularly for multi-drug resistant and cerebral malaria. However, the concentration of artemisinin in the plant is very low. Because the chemical synthesis of artemisinin is complicated and not economically feasible in view of the poor yield of the drug, the intact plant remains the only viable source of artemisinin production. Therefore, it is necessary to increase the concentration of artemisinin in A. annua to reduce the cost of artemisinin based antimalarial drugs. Plant scientists have focused their efforts on A. annua for a higher artemisinin crop yield. With the present volume, we are bringing together the research which is being done on this plant throughout the world and future possibilities for scientists and researchers who want to work on it.

Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2008 in the subject Engineering - Chemical Engineering, grade: A, Bahir Dar University (Bahir Dar University Engineering Faculity), course: Chemical Engineering, language: English, abstract: Abstract Malaria disease is endemic in least developed countries like Ethiopia. The rapid development of drug-resistant malaria parasite strain leaves the need for new effective anti-malarial drugs. Artemisinin is a sesquiterpene lactone found in the leaves and flowers of plants Artemisia annua L and have different chemical structures and higher efficacy than others. The content of artemisinin is very small and from 0.5 to 1.2 % of dry weight of plants in Ethiopia. Extraction of artemisinin from Artemisia annua is mainly performed using hydrocarbon extraction processes. Extraction with Supercritical CO2, ethanol, ionic liquids, hydroflourocarbon HFC-134a and hexane extraction are extraction technologies and compared majorly in terms of their extraction efficiency, cost and drawback to environment. Since artemisinin is only present in the epidermis of the leaves, leaves were only washed on the outside by stirring appeared to be the most appropriate method and the first step in this research was solvent extraction using hexane. Step followed purify by repeated crystallization. Laboratory scale production data and procedures were listed for aremisinin extraction process. By using those data large scale production method was designed. And did material and energy balance calculations for large scale production process carried out by taking scientific approach followed by feasibility study. As a result my extractor was very large and it has 14.37m3 capacities it wasn’t found in market. So I designed the required larger extractor that should fulfill the target of the project i.e. with simple, rapid, cost effective, environmental friendly and practical method for the isolation of artemisinin from Artemisia annua. The design the extractor I used the optimum ratio between solvent and leaves, optimum extraction time, optimum extraction temperature and optimum design of the stirrer paddles. In these thesis work extractor design, skirt design, bolt design, reinforcement calculations, preliminary equipment design (sizing), economic analysis calculations were included. In the profitability analysis Return on investment, payback period and net present worth calculated and the project was checked its feasibility. The payback period is 1.22yrs and it is economically acceptable that means this market is promising in Ethiopia in addition to save millions of Ethiopian and African from killer malaria. Key words: artemisinin, sesquiterpene lactone, hexane extraction

Download or read book A Detailed Chronological Record of Project 523 and the Discovery and Development of Qinghaosu Artemisinin written by Zhang Jianfang and published by Strategic Book Publishing. This book was released on 2013 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an account of a project in China carried out in secrecy from the Chinese people and the Western World during the tumultuous years of the Cultural Revolution. Project 523, as it was called, resulted in one of the most significant advances in the treatment of malaria since the discovery and first use of quinine over 300 years ago. The origin of the project was a request from the North Vietnamese Government to Mao Zedong in China, for assistance in managing chloroquine drug-resistant malaria affecting their military forces during the Vietnam-American war. Initially the project was directed by the Chinese military medical research authorities, but it became so large that civilian scientists were called upon to help. Ultimately, to accomplish this task, over 60 institutions and more than 500 scientists and other personnel scattered throughout mainland China became involved. This achievement is all the more remarkable because it was accomplished during the Cultural Revolution using obsolete equipment, and at a time when all regular research was halted, scientists were harassed and denigrated, and academic and intellectual activity was discouraged or even forbidden. The drug discovered - artemisinin from the plant Qinghao (Artemisia annua L) - is now the most widely used treatment for malaria in the world.

Download or read book Saving Lives Buying Time written by Institute of Medicine and published by National Academies Press. This book was released on 2004-09-09 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 50 years, low-cost antimalarial drugs silently saved millions of lives and cured billions of debilitating infections. Today, however, these drugs no longer work against the deadliest form of malaria that exists throughout the world. Malaria deaths in sub-Saharan Africaâ€"currently just over one million per yearâ€"are rising because of increased resistance to the old, inexpensive drugs. Although effective new drugs called "artemisinins" are available, they are unaffordable for the majority of the affected population, even at a cost of one dollar per course. Saving Lives, Buying Time: Economics of Malaria Drugs in an Age of Resistance examines the history of malaria treatments, provides an overview of the current drug crisis, and offers recommendations on maximizing access to and effectiveness of antimalarial drugs. The book finds that most people in endemic countries will not have access to currently effective combination treatments, which should include an artemisinin, without financing from the global community. Without funding for effective treatment, malaria mortality could double over the next 10 to 20 years and transmission will intensify.
