Abstract

Pu'er tea served as main ingredient in conjunction with extracts of chrysanthemum, bamboo leaves and tremella was developed to be pie-shaped compound Pu’er tea, compound Pu'er tea bags and instant compound Pu'er tea. The sensory evaluation of the compound Pu'er tea and its feedstock were carried out,and their quality and texture chemicals such as tea polyphenols, free amino acid , caffeine water-soluble saccharides, crude fiber and total ash was assayed. The hydroxyl radical scavenging rates of the compound pu’er tea reached levels of 47-70%.The splenocyte treated with instant compound Pu'er tea had significantly lower splenocyte proliferative responding to ConA (P < 0.01), which did not yet perform in a dose-dependent manner.
