The article in recent years the research progress of disease of oral cavity of TP prevention and cure makes one overview. The compositive TP of the basic research 1.1 TP of 1 TP is the floorboard that phenolic apperception of a kind of many hydroxyl closes matter, 25% what hold tea dry weight about, its are main component includes to express gallnut of gallnut catechu element gallnut of element of catechu of gallnut of acerbity ester, watch, watch catechu element is acerbity element of catechu of ester, watch, express gallnut of gallnut catechu element among them acerbity ester content is highest, occupy the 80%[1] of catechu element about, fighting oxidation with its unique element structure, fight the position with fight the respect such as tumor to have choppy, significant. The 1.2 TP absorption in oral cavity and metabolization Lee [2] is measured normally inside a hour after healthy person is chewing green tea Xie Huo contains juice of gargle green tea, content of the TP in saliva is very high, after observing green tea passes salivary enzymatic hydrolyze, TP is slow release and in oral cavity;Yang of local play action [the salivary level after 3] checked 6 volunteers to drink tea, chroma of the TP in making clear the saliva after drinking tea as a result is serous TP pH indicator 2 times, and the salivary TP concentration that contains gargle tea solution a few minutes to be able to produce higher level, and TP can be absorbed through oral cavity mucous membrane.

Alkyl gallates can also low the extent of lipid peroxidation. To investigate the effects of PG and AG on livers that were injured by tetrachloride, we treamed small mice and fed them with different medicines, The conclusion is that AG and PG could scavenge free radical and protect mice livers from injuring by tetrachloride, AG was more effective than PG. 4. 3 The results of experiment for scavenging free radical of alkyl gallate in vitro showed that alkyl gallates can effectively scavenging free radical, but the parent gallic acid showed little effect. This suggested that introducing of hydrophobic group could significantly improve the anti-oxidative ability of gallic acid derivatives at large extent.
