Six flavonoids camelliquercetiside C ( 1 ), epigallocatechin 3‐ O ‐gallate ( 2) , rutin ( 3 ), quercetin‐3‐ O‐β ‐D‐glucopyranoside ( 4 ), epicatechin ( 5 ), and epigallocatechin ( 6 ) were isolated from the methanol extract of the leaves of Camellia sinensis by using combined chromatographic methods. Their structures were identified on the basis of spectroscopic evidence and by comparison with those reported in the literature.
