Quantitative and Qualitative Analysis of (-)-epigallocatechin Gallate from Green Tea by LC-MS

Objective: To study the rapid analysis of a natural product using parallel processing of High Performance Liquid Chromatography (HPLC) with on-line mass detection. Materials and methods: The parallel processing of HPLC with mass detection(LC-MS) was used to decrease the cycle time between the analysis, such as (-)-epigallocatechin gallate (EGCG) from green tea. Results and conclusion: The parallel processing LC-MS method provided a rapid procedure for qualitative and quantitative analysis of EGCG from green tea sample.
