“…This contamination via drinking water initially affects the gastro-intestinal (GI) tract and the intestinal epithelial cells. The green tea has been suggested to perform as therapeutic agents against this toxicity [11]. Most abundantly used hepatic toxicity model is the CCL4 treated rat model.…”

“…During growth, buds may be shielded from sunlight in order to reduce the chlorophyll content, which makes the leaves appear white (Kim et al 2015). White tea has been reported to possess many health benefits, including antioxidant (Damiani et al 2014), antibacterial (Tomaszewska et al 2015), and anti-cancer (Hajiaghaalipour et al 2015) effects, as well as other properties (Song et al 2015). The strong antioxidant capacity of white tea is connected with its high catechin content (Azman et al 2014).…”

The aim of this study was to investigate the effect of water quality on the main components in Fuding white tea infusions, including catechins, caffeine, theanine and free amino acids. Pure, tap and spring water were tested, and water quality was found to have a distinct effect on the main compounds extracted. Pure water, which was weakly acidic and low in dissolved ions, achieved the highest catechin content, whereas caffeine and theanine, and amino acids, were higher in infusions made with spring and tap water, respectively. Sensory evaluation was performed to evaluate infusion colour, taste and aroma, and sensory quality was similarly influenced by water type, due primarily to differences in dissolved ions. Pure water was more suitable for brewing white tea with superior colour, aroma and taste.

“…The protective effect of tea has been linked with the presence of polyphenolic contents such as catechins and tannic acid (Tomaszewska et al, 2015) and these compounds were shown to have a considerable antioxidant capacity against oxidative free radical (Gramza et al, 2005). We therefore estimated the free radical scavenging activity of AGTE by both DPPH (92.62%) and β-carotene (88.3% and 97.6% at 500 and 1000 μg/mL respectively) tests.…”

Background: This study aims to examine the protective effect of green tea on the disturbances in oxidative stress and apoptosis related factors, mostly produced due to perinatal lipopolysaccharide (LPS) exposure, that subsequently induces liver cell damage. Materials and Methods: Anti-free radical, Antioxidant, scavenging, geno-protective, and antiapoptotic activity of aqueous green tea extract (AGTE) were assessed against LPS-induced hepatic dysfunction in newborn-rats. AGTE at doses of 100 & 200 mg/kg was orally administered daily to rat dams, during gestation and lactation. Results: AGTE was observed to exhibit protective effects by significantly attenuating LPS-induced alterations in serum AST, ALT, bilirubin, and albumin levels. Significant increase in the total antioxidant capacity (TAC), DNA contents, and reduction in nitric oxide (NO) levels were observed in AGTE treated rats comparing LPS-toxicated ones. Additionally, AGTE treatment significantly down-regulated apoptotic markers and this effect was directly correlated to the degree of hepatic fibrosis. The possible mechanisms of the potential therapeutic-liver protective effect of AGTE could be due to free radical scavenging potential and antiapoptotic properties caused by the presence of antioxidant polyphenolic components in AGTE. Conclusion: We thereby propose, based on our findings, that the anti-free radical and anti-apoptotic inducing properties of AGTE active constituents attribute to its functional efficacy as anti-fibrotic agent.
