Catechin

life of foods by modifying the physiochemical and biological properties of the food (Martin et al. 2009). Polyphenol (or catechins) extracted from green tea extract have shown an excellent antimicrobial effect against Bacillus Subtilis, Escherichia Coli, Proteus Vulgaris, Pseudomonas Fluorescents, Salmonella sp. and Staphylococcus Aureus (Bancirova 2010). Among all the catechins, epigallocatechin-3-gallate (EGCG) and…

4.3 High Performance Liquid Chromatography (HPLC) An HPLC analysis was carried out for the Fraction C2-7 for confirmation of the results obtained by TLC analysis. According to the HPLC chromatogram, there is only one peak was observed at the retention time of 4.510 minutes. Therefore, it can be concluded that there is only one compound presents in the Fraction C2-7. Basically, the first few small peaks in the chromatogram which is around 2-3 minutes are ‘noise’ from the injection that been made…

olefin and 1513 cm-1 for arene , 1240 cm-1 for alcohol and phenol, 1159 and 1112 cm-1 for ether group, 1448 cm-1 for alkanes, 567 cm-1 for alkyl bromide which were closely similar to Catechin. No other visible peaks were observed in the spectra which indicate that a simple soxhlet extraction itself yields Catechin with fewer…

Resveratrol in red wine is just one of the hypothetical explanations of what causes the French paradox, with the others such as catechin and quercetin, explained in chapter 5.3, which are found in red wine that has the same effects as resveratrol. Another possible explanation for the French paradox is the high intake of foods rich in folate or folic acid of the French people, which…

by clinical research. 1. Bioactive Compounds Improve Health It is more than colored water. Brewing the tea leaves releases a number of the bioactive infusing the water with vital nutrients. It is stacked with polyphenols like flavonoids and catechins, which work to reinforce the body's cells. By helping to reduce the formation of free…

One of the best-known polyphenols found in red wine is resveratrol. A number of studies have demonstrated the anti-inflammatory activity of resveratrol and its ability to promote a healthy inflammatory response.121 Like oleocanthal and a number of the other polyphenols already mentioned, resveratrol seems to exhibit its anti-inflammatory activity mostly through inhibition of the COX enzymes, which has the potential to promote a healthy inflammatory response.122 Resveratrol also seems to modulate…

2.0 INTRODUCTION Consumption of foods and beverages that do not have added preservative but able to have a longer shelf life has become very popular among the consumer. In order to improve the shelf life of a food product, adding natural food extracts that act as the antimicrobial are able to inhibit or supress the microbial growth (Martin et al 2009). Microbial growth, pH and the storage temperature are the important measure of the shelf life and quality of a food product (Fellers 1988;…

of green tea is seen in its effectivity in burning fat. • Besides lowering stress, green tea lowers blood pressure and oxidative stress in the body. The liquid is thus boon for those suffering from high blood pressure. • The high amounts of EGCG (catechin polyphenol) present in green tea helps avoid any kind of damage to arteries or vessels pumping from the heart. Thus mortality due to cardiovascular reasons like stroke, thrombosis, arteriosclerosis etc. can be reduced with regular consumption…

as neurological diseases (Chacko et al, 2010). The third harmful effect that could possibly come from tea overconsumption is a decrease in iron bioavailability. As previously stated, tea contains the flavanol monomer catechin (Ruxton, 2008). Specifically in green tea, the catechins may have an attraction to iron and when consumed in the form of infusions, it can greatly decrease the iron bioavailability in ones diet (Chacko et al, 2010). As with any food or beverage that is consumed,…

takes this round. Oolong vs green Tea: advantages A great deal has already been written about the antioxidant houses of green tea and the way it is able to even help reduce risks of cancer and different diseases. Oolong tea has lower ranges of catechins and polyphenols than green tea. green tea has been researched and marketed so much for weight loss that it has to turn out to be a de facto calorie buster, even though the clinical evidence is inconclusive. In truth, experts say that consuming…
