THE Chemistry,Metabolism AND Biological Activities OF GINSENG - 张均田 主编
2006年9月 Ginseng,the root and rhizome of Panax ginseng CA Meyer has been used as a tonic remedy in Chinese traditional medicine for over 2000 years. In 200 AD when this herb was described in the oldest Chinese material medica book,Shen Nong Ben Cao Jing,the author depicted many pharmacological functions of ginseng including improving cognition and thought,invigorating body,harmonizing energies,removing toxic substances and prolong life and so on. So,it has been used as a tonic or a remedy individually or in combination with other medicines for treating a certain kinds of diseases.
In the past decades,scientists not only in Asian,but also in the Western countries paid great attention to ginseng research. Every year,there are hundreds of papers published and new uses for ginseng discovered.
This monograph is aimed at to review the recent advances in chemistry,metabolism and biological activities of ginseng. The invited authors are engaged in ginseng research for a long time and accumulated rich experience.My friend,Mr W J Zhao is a enterpriser and is now studying in Jilin University for PhD degree.He works on ginseng research with great enthusiasm and contributes a lot.I appreciate him not only for providing us two articles, but also for giving us generous support.Indeed,their articles are full of new idea,new thought and new technology as well. Some finding of new use is the new discoveries for the first time in the world.
More than thirty years ago,nothing was known about the chemical structure of active principles of ginseng. Today,ginsenosides and nonsaponin constituents have been isolated and identified. Some proteins,peptides and polysaccharides were proved as active principles. According to the worldwide research,ginseng and ginsenosides were shown to have miraculous effects. One of noticeable effects is delaying aging,dysfunction appeared in agerelated disorders such as aging and AD induced cognition impairment,stress induced low sexual function,estrogendeficient induced osteoporosis,etc. were improved much better with ginseng. Interestingly,the declining of vital functions could be restored to normal level by ginseng or its active principles. In addition,there are two prominent features in ginseng’s pharmacology. First,ginseng exhibited effects on multiple targets simultaneously. But ginseng showed almost no toxic and without any noxious side effects. Second,ginseng effect is characterized by increasing neural plasticity or mobilizing endogenous protective mechanism (e.g. increase of neurotrophins and neuroprotective gene products as well as antioxidant enzymes). These characters of ginseng are different from western medicine but fit the conception of Chinese traditional medicine. For metabolism of ginseng,there are two questions about ginsenoside metabolism arose from academic field. That is,whether ginsenosides can pass through bloodbrain barrier or not? Ginsenoside exert its effect is in its prototype or in the form. of metabolites? The chapter of ginseng metabolism in this book will answer these questions.
At present,ginseng research situation is just like the stage of steroid hormone and prostaglandins whose multiple biological activities and clinical application were proved and recognized generally. Therefore,the tasks in the future should carry out extract,total or semisynthesis of ginsenosides and other principles with industryscale.The further study on the mechanism of action,pharmacokinetics and clinical trail with design of doubleblind and placebo control is also needed.
At last,I wish to thank all authors for their providing us interesting and informative date and sending papers in due time. I also extend my thanks to Chemical Industry Press for their patience in dealing with of organizing and editing this book. In addition,I’d like to extend my thanks to my wife for her understanding,taking care of and providing me with time and encouragement.
