The Wolfberry Bud Tea has Enhanced Antioxidant Activities - Abstract
Wolfberry bud tea and leaf tea have been consumed as anti-aging drinks in China and Far East Asia for years. However, the capacity against oxidative stress is not well documented. Inthis study, the total phenolics and flavonoids were extracted with 55 % ethanol and the contents were measured in samples of three wolfberry
bud tea and three wolfberry leaf tea, respectively. The antioxidant activity were characterized by the FRAP and DPPH assays. The results showed that contents of total phenolics and flavonoids and the antioxidant activity were higher in the wolfberry bud tea than those in the wolfberry leaf tea. The antioxidant activity in wolfberry bud tea was significantly correlated with the contents of total phenolics and flavonoids. Data
suggested that the wolfberry bud tea may serve as a significant source of natural flavonoids and /or phenolics against oxidative stress.
