Data expressed as mean values ± SD (n = 3). For each analyte, different superscript capitals (A–H) indicate significant differences (p < 0.05). Codification of the compounds is given in Figure 1. Abbreviations: MEB, MEZ: methanol-water (7:3, v/v) extracts of C. bullatus and C. zabelii leaves, respectively; TCA, total content of caffeic acid derivatives; TFL, total flavonoid content; TLPA, total content of low-molecular flavanols and proanthocyanidins; TPH, total phenolic content (HPLC-PDA peaks); TPA, total content of proanthocyanidins (n-butanol/HCl assay) expressed in CYE and adopted from [6].
