“…In this study, the selected grass ecotype was characterized by higher DM contents, whilst legumes (MP, MA, TC and TR) were characterized by a higher CP content. As reported previously (Rumball et al ., ; Jankovic et al ., ), PL had high levels of phenols with PT and Tann concentrations approximately twofold higher than observed in the other legumes and grass ecotypes included in this study (Table , P < 0·01). Phenological stage affected all chemical parameters with DM increasing from vegetative to reproductive (+73%; P < 0·01), whereas other parameters decreased, including: phenol content, CP (−50%; P < 0·01) and EE (−20%; P < 0·04).…”

Plant phenols can influence utilization of forages by ruminants through binding with proteins either by complexing with oxidized phenols (products of polyphenol oxidase activity or formed in oxidizing conditions) or by hydrogen binding with tannins. These protein-bound phenols (PBPs) affect rumen metabolism by inhibition of both proteolysis and lipolysis. The aim of this work was to assess the level of polyphenol oxidase (PPO) activity (determined with a range of diphenolic substrates), PBP content, and to identify the main source of variation in different forage ecotypes harvested at different phenological stages. PPO activity was strongly influenced by substrate type with a significant effect of forage ecotype. Forage ecotype and phenological stage also influenced PPO and PBP content. PPO showed a strong relationship with dry matter and phenol content of plants.

“…Compared to our results, Kobeasy et al [28] reported significantly lower TPC (13.05 mg GAE/g dw) in aqueous extracts of P. major leaves. Dalar et al [30] reported close-ranged values for TPC in an acidified methanol extract of P. lanceolata leaves (35.30 mg GAE/g dw), while Janković et al [13] reported 24.97 mg GAE/g dw TPC in a 50% water-ethanol extract of P. lanceolata leaves.

The leaves of Plantago species have been known as a rich source of polysaccharides, polyphenols, and iridoids. In the recent years, some authors have examined the relative influence of carbohydrate compositions and polyphenols on their antioxidant and prebiotic activity. In this study enzymatic hydrolysis of Plantago major, Plantago lanceolata, and Plantago media leaves with hemicellulase and xylanase was carried out. The chemical composition of the enzyme‐derived hydrolysis products was determined. Their antioxidant activity was evaluated using 2,2‐diphenyl‐2‐picryl‐hydrazyl‐hydrate, ferric reducing antioxidant power, and cupric reducing antioxidant capacity assays. The utilization of the carbohydrate complex from the obtained hydrolysates to stimulate the production of certain glycohydrolases from Lactobacillus plantarum probiotic strains was investigated. The HPLC analysis of the hydrolysis products showed the presence of galactose and arabinose in 1:3 and 1:4 ratios. The highest concentration of total sugars was determined in P. major hydrolysates with hemicellulase (386.71 mg/g dry weight). The antioxidant activity according to the three methods was the highest in P. media hydrolysates, which correlated with their total phenolic concentration. L. plantarum S27 showed the highest values of α‐galactosidase activity at the 24‐h fermentation process when it was cultivated in a broth with the presence of P. major hydrolysates with hemicellulase and xylanase (0.129 U/mg and 0.133 U/mg, respectively).

“…Visual detection of caffeic acid glycosides can also be obtained using anisaldehyde-sulphuric acid (105 8C 4 min) (Jankovic et al, 2012), and vanillin-sulphuric acid (heat at 105 8C for 2-3 min) (Kirmizibekmez et al, 2009). If reagents with sulphuric acid are used, silica gel plates or other acid-resistant plates are required, since the heat applied to principally detect the sugar moieties of plantamajoside will burn the cellulose plates and no compounds can be detected.…”
