was expressed as gram of
241 gallic acid equivalent per 100 g of dry matter (g GAE/100 g DM) using a gallic acid standard curve.
242 Determination of Total Flavonoids Content
243 The total flavonoids content was determined (Yang et al., 2009) in triplicate. The standard and
244 extract (250 μL each) were put into a centrifuge tube and 1.25 mL of distilled water added. About
245 75 μL of 5% NaNO2 was added, the mixture shaken and allowed to stand for 5 min in the dark at
246 room temperature. About 150 μL of 10% AlCl3 was added, the mixture shaken and kept in the dark
247 for 6 min. 1 M NaOH (500 μL) and 775 μL of distilled water were added and absorbance measured
248 at 510 nm. The total flavonoids content was expressed as milligram of catechin equivalent per gram
249 of dry matter (mg CE/g DM).
250 Determination of Antioxidant Activity
251 The DPPH radical scavenging activity was determined in triplicate as described by Karioti et al.
252 (2004). The standard and extract (20 μL each) were put into Eppendorf tube, 800 μL of absolute
253 methanol added and the mixture shaken. Solution of 0.1 mM DPPH (1 mL) was added, the mixture…
Green tea is rich in polyphenols like flavonoids and catechins which function as antioxidants. With increasing age, the body produces greater number of free radicals which deteriorate cells and accelerate the aging process. This leads to wrinkles, lusterless skin, stiffness in muscles and other signs of aging. Antioxidants present in green tea affect the release of free radicals and limit their production in the body. As a result, they control the pace of aging delay the signs of…

The obesity problem became the one of the biggest problems among…
It even offers stronger benefits in some areas when compared to black tea. The history of green tea goes back as far 2737 BC. In the 15th-century Chinese seamen were given green tea to prevent scurvy which could take lives of many of their European counterparts more than 100 years later. 15% of dried green tea is made up of catechins. Catechins have the property of anti-microbial actions.

determined using aluminium chloride (AlCl3) colorimetric method. A calibration curve for total flavonoids content of catechin with concentration of 20, 40, 60, 80 and 100 μg/mL shown in Figure 4.5 and the results were expressed as catechin equivalents (CA)/g of samples.
Figure 4.5: Standard curve of catechin.
From the standard curve, an equation was obtained from the straight line, where y = 0.0028x + 0.0081 (R2 = 0.9983). The total flavonoids content can be calculated using the same formula…
Consumption of foods and beverages that encourages a healthy living, better health and lowering the risk of sickness has become very popular among the consumer whom are health conscious. Hence, a lot more attention is paid to different food extracts such as green tea extracts, grape seed extracts and ginger extracts as they posed excellent antimicrobial, antioxidant and anti-carcinogenic properties (Martin et al. 2009). These extracts have great potential in improving the quality…
natural food extracts may be another good alternative not only to maintain the original juice nutrient quality. These extracts also have great potential in improving the quality and shelf life of foods by modifying the physiochemical and biological properties of the food (Martin et al. 2009).
