Natural Product Isolation and Detection of Glyco-lipids in Tea
Tea is one of the most widely consumed beverages worldwide, but not much is known about the glycolipids found in tea. This project is focused on isolating and characterizing glycolipids and understanding how they may contribute to the health benefits and sensory attributes of tea. In order to do so, we are developing mass spectrometry and high sensitivity screening protocols for analyzing nano-nutrients in aqueous solutions and using our laboratory’s chemical technologies to synthesize internal standards, which may be hard to obtain or commercially unavailable.
