Fig. 4From: Characterization of tea leaf metabolites dependent on tea (Camellia sinensis) plant age through 1H NMR-based metabolomicsRelative changes or variations of individual metabolites of fresh tea leaves from 8- and 25-year-old tea plants (April 2016) and 8- and 25-year-old tea plants (May 2015). Different small letters in the vertical graph bars of the leaves indicate significant differences between the samples, which were determined by Duncan’s multiple range test at P < 0.05. The error bars were based on ten samples. Ara, 2-O-(β-l-arabinopyranosyl)-myo-inositol; GABA, γ-aminobutyrate; EC, epicatechin; ECG, epicatechin gallate; EGC, epigallocatechin; EGCG, epigallocatechin gallate; EGCG3ʺMe, epigallocatechin 3-O-(3″-O-methyl) gallateBack to article page
