Study The Biological Functions Of Tea On Caenorhabditis Elegans

Tea is one of the three greatest beverages in the world with a history of thousands of years. There are many benefits including antiviral, antibacterial, antiaging, decline fat to reduce weight etc. Recently, study Pu-erh Tea more and more. We have determined composition of pu-erh tea powder and study biologic effects of green tea extract, black tea extract and Pu-erh Tea extract on Caenorhabditis elegans. High dose of tea powder delay development, reduce number of egg-laying, shorten the lifespan. But Pu-erh tea powder are much slighter than green tea powder and black tea powder. Moderate dose of Pu-erh tea significantly enhanced the movement ability of C.elegans. We also study biologic effects of caffeine on movement, pharyngeal pumping ,egg-laying and development in Caenorhabditis elegans.
