Abstract

Camellia sinensis (L.) Kuntze (green tea) is an evergreen shrub which is grown in China, India, Sri Lanka, Japan, Indonesia, Kenya, Turkey, Pakistan and Argentina [1]. It is a member of Theaceae family. The leaves of C. sinensis contain caffeine and various phenolic compounds (e.g. epicatechin, epicatechin gallate, epigallocatechin, epigallocatechin gallate, quercetin, myricetin) [2]. C. sinensis is presented in herbal slimming products due to its diuretic and promoting of lipolysis effects [1]. In the present study, new, simple and sensitive high performance liquid chromatography (HPLC) methods have been developed for qualitative and quantitative determination of epigallocatechin gallate, epigallocatechin, epicatechin gallate and catechin in seven herbal slimming products containing Camellia sinensis in Turkey. The developed methods can be used for routine quality control analysis of epigallocatechin gallate, epigallocatechin, epicatechin gallate and catechin in different herbal slimming products.
