Figure 3From: Genetic variation and metabolic pathway intricacy govern the active compound content and quality of the Chinese medicinal plant Lonicera japonica thunb The active compound contents in flowering samples of FLJ and rFLJ. (A) The content of eight compounds: chlorogenic acid, caffeic acid, ferulic acid, rutin, luteoloside, hyperoside, quercitrin and quercetin (mg/g DW), as analyzed by using HPLC and calculated based on a linear formula ( Additional file 2: Table S2). Error bars (SEs; n = 5) were calculated by using Excel software. (B) The content of volatile compounds (Metabolite/pentadecanol [IS] peak area ratio/1000) in FLJ and rFLJ. The Y axis indicates the relative quantification of metabolites by normalization of their response values to pentadecanol.Back to article page
