The life science and the rise of human development, is undoubtedly the brilliant achievements of 1953, when DNA (DNA ) double helical structure mapping and beautiful beautifully rendered in front of human scientists, finally opened the " Mysteries of life " the mysterious door. Thus for biology, medicine research provides scientific basis and research direction.
In 1956 the United States California university professor Haman study found, the body of free radicals ( FR ) combined with DNA, will cause the small portion of the DNA base substitution or lost, if not timely repair or removal, will make the offspring DNA repeat replication, cause the body's normal physiological and biochemical processes of recession or disorder, the cause of human aging and various diseases the occurrence of. This discovery by scientists agree, which created the free radical biology and medicine the frontier disciplines, many biologists and medical scientists to begin research and seek to free radical scavenging material, lets the human fundamentally from illness and pain. On 1995, free radical biology professor Haman won the Nobel Prize in medicine.
When foreign numerous scientists devoted to looking for the free radical scavenging material research, scientists in China are positive action, Zhejiang University biologist ( Professor Yang Xianqiang, home of tea polyphenols on the earliest, the most successful one of the experts ) in nearly half a century of exploration and research, successfully from a millennium science culture tea is found in natural, efficient free radical scavenger, tea essence -- tea polyphenol!
Yang Xianqiang professor of history:
1960-1985, biochemistry of tea based on.
In 1986, successfully extracted from tea effective components -- tea polyphenol.
On 1987, the Zhejiang Department of Kasetsart University tea combined with Zhejiang Medical University, Zhejiang College of Traditional Chinese Medicine ( now Zhejiang Chinese Medicine University) and the Zhejiang University Department of chemical engineering was established interdisciplinary tea polyphenols research group, Professor Yang Xianqiang served as team leader.
In 1989, Professor Yang Xianqiang led the research team, in the National Natural Science Fund and Zhejiang Province Natural Science Fund, system development of tea polyphenol scavenging free radical research and achieved significant results. Prior to this, scientists worldwide have screened nearly a thousand kinds of organism under study, but progress is slow, but Professor Yang Xianqiang led the research team, to the interdisciplinary research, accurate to overcome this problem, find out the best drug free radical scavenging.
1990-2000, tea polyphenol pharmacological research system, and implementation of the clinical basic research. Development of functional components in tea polyphenols as drug and health food.
In 1995, in the world of antioxidants and health symposium, Professor Yang Xianqiang has published tea polyphenols applied to clinical observations, got the attention of many researchers and high evaluation, thus establishing the tea polyphenols in free radical biomedicine have equal status.
In 1998, tea polyphenols and purification of EGCG monomer separation technology research.
In 2003, in the "Chinese Excellence Fund " funding, published the world's first academic monographs " -- tea polyphenol tea polyphenols chemistry ".
