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 of Green Sencha
In the investigation of theaflavin-enriched green tea extract in association with cholesterol levels of the study of "Cholesterol-lowering effect of a theaflavin-enriched green tea extract: a randomized controlled trial" by Maron DJ, Lu GP, Cai NS, Wu ZG, Li YH, Chen H, Zhu JQ, Jin XJ, Wouters BC, Zhao J.[9a], researchers found that The theaflavin-enriched green tea extract is an effective adjunct to a low-saturated-fat diet to reduce LDL-C in hypercholesterolemic adults and is well tolerated.
b. In the observation of the effect of green tea beverage and green tea extract on lipid changes of the study of "Green tea intake lowers fasting serum total and LDL cholesterol in adults: a meta-analysis of 14 randomized controlled trials" by Zheng XX, Xu YL, Li SH, Liu XX, Hui R, Huang XH.[9b], researchers found that the administration of green tea beverages or extracts resulted in significant reductions in serum TC and LDL-cholesterol concentrations, but no effect on HDL cholesterol was observed.
c. In the assessment of Protective effects of green tea against high-cholesterol diet of the study of "Protective effects of green tea against hepatic injury induced by high-cholesterol diet in rats: histopathological analysis, oxidative DNA damage and COX-2 expression" by de Moraes BB, Pasquini G, Aguiar O Jr, Gollücke AP, Ihara SS, Tenorio NM, Andersen ML, Catharino RR, Spadari-Bratfisch RC, Ribeiro DA., researchers found that daily administration of green tea for at least 7 days displays some preventive properties as indicated by COX-2 downregulation and decreased oxidative DNA damage.
d. In the determmination of green tea extract and improved hypocholesterolemic effects of tyhe study of "Nanoemulsified green tea extract shows improved hypocholesterolemic effects in C57BL/6 mice" by Kim YJ, Houng SJ, Kim JH, Kim YR, Ji HG, Lee SJ.[9d]. researchers found that nanoemulsification significantly increased hypocholesterolemic effects of GTE in vivo due to increased bioavailability.
