Sencha is a type of decoct Japanese green tea, most popular tea in Japan, made from the dried tea leaves without grinding the tea leaves. It volatile compounds could be used as markers for the overall quality evaluation of all green teas, according to the study of "Predication of Japanese green tea (Sen-cha) ranking by volatile profiling using gas chromatography mass spectrometry and multivariate analysis" by Jumtee K, Komura H, Bamba T, Fukusaki E..
Health Benefits and green Sencha
16. Gastrointestinal diseases
a. In the evaluation of different doses of green tea extract and inflammatory bowel disease of the study of "Comparative evaluation of different doses of green tea extract alone and in combination with sulfasalazine in experimentally induced inflammatory bowel disease in rats" by Byrav DS, Medhi B, Vaiphei K, Chakrabarti A, Khanduja KL.[16a], researchers showed that green tea alone and in combination with sulfasalazine reduced inflammatory changes induced by tri nitro benzene sulfonic acid in rats.
b. In the examination of the role of polyphenols in gastrointestinal diseases of the study of "Polyphenols and gastrointestinal diseases" by Dryden GW, Song M, McClain C.[16b], researchers erote that Substantial in-vitro and animal studies support the beneficial effects of polyphenols in many gastrointestinal diseases. Well designed multicenter trials in humans, such as those called for in the 2005 National Institutes of Health Requests for Applications for Silymarin Centers, will be critical for defining the safety, appropriate dosing and therapeutic efficacy of such agents.
c. In the examination of flavonoid found a abundantly in green tea and intestinal neoplasia of the study of "Emerging role of bioflavonoids in gastroenterology: Especially their effects on intestinal neoplasia" by Hoensch HP, Oertel R.[16c], researchers found that Flavonoids can inhibit inflammatory pathways and could be useful for chronic inflammatory bowel diseases. Flavonoid deficiency syndromes could be therapeutic targets in the future.
d. In the evaluation of "(-)-epigallocatechin-3-gallate (EGCG), a green tea and gastrointestinal tract of the study of "Development of (-)-epigallocatechin-3-gallate (EGCG)-loaded enteric microparticles with intestinal mucoadhesive property" by Onoue S, Ochi M, Yamada S.[16d], researchers found that although significant improvement in chemical and metabolic stability of EGCG was observed in the EGCG/MS, possibly due to the controlled release and/or bioadhesion. From these findings, newly prepared EGCG/MS might be of clinical importance in both stabilizing and delivering EGCG for treatment of intestinal diseases.
