Figure 5.

Quantitative data of G. procumbens dry leaf extracts: (a) proanthocyanidins; (b) phenolic acids; (c) flavonoid aglycones after acid hydrolysis; and (d) native flavonoids.

Figure 5

All data expressed as mean values calculated per dry weight of the extracts ± SD (n = 3 × 3 × 1) represented by error bars. For each parameter different letters in parentheses indicate significant differences (p < 0.05). Abbreviations: TPA, total proanthocyanidin content expressed in cyanidin chloride equivalents; TLPA, total content of individual proanthocyanidins expressed in epicatechin equivalents; ECA, (−)-epicatechin; PA, procyanidin A-type trimer; TPHA, total content of phenolic acids; CHA, 5-O-caffeoylquinic acid; NCHA, 3-O-caffeoylquinic acid; CCHA, 4-O-caffeoylquinic acid; SPHA, total content of simple hydroxybenzoic and hydroxycinnamic acids; TFA, total flavonoid content as the sum of aglycones after acid hydrolysis; TFL, total content of individual native flavonoids; QU, quercetin; KA, kaempferol; HY, hyperoside; MQ, miquelianin. All levels found by HPLC-PDA-fingerprints except for the TPA contents assayed by spectrophotometry. For extract codes see Figure 1.
