Analysis of (-)-epigallocatechin gallate in human serum obtained after ingesting green tea

Biosci Biotechnol Biochem. 1996 Dec;60(12):2066-8. doi: 10.1271/bbb.60.2066.


A method for analyzing the EGCg concentration in human serum was developed by using high-performance liquid chromatography with electrochemical detection. EGCg was detected in human serum after the ingestion of 5 g of green tea powder (matsu-cha) dissolved in 200 ml of hot water. The concentration of EGCg in the serum reached the highest level about 2 h after ingesting the green tea, and then decreased.
