Summary: Panax ginseng C.A.Mey. is an Araliaceae Panax plant. Along with mink and antler, ginseng is one of the three treasures of Northeast of China, and is a valuable medicine and health care product. The "King of Herbs" is known around the globe; however, a comprehensive source of information on its use is needed. This book is based on a study of 45 samples of ginseng collected from Jilin Province, Heilongjiang Province, Liaoning Province and Korea. These samples, which included 3, 4 and 5-year-old ginseng, were analyzed for various constituents, such as ginsenosides and polysaccharides, providing extensive scientific data. This book not only focuses on the methods of analyzing the nutritional content and functional factors in ginseng, but also presents the findings of these analyses. Uncovering the mysteries of ginseng, offering scientific-technological insights and comparing domestic and foreign ginseng, it is a valuable reference resource for researchers and consumers alike.
