“…A reverse‐phase column (Phenomenex Kinetex biphenyl, 10 × 2.1 mm, 5 μm particles, 100 Å pore, shell‐core), with safeguard precolumn (Phenomenex Phenyl, 4 × 2.0 mm), thermostated at 35 ± 1°C, was used (Tamasi et al, ). The eluents were as follows: (A) H 2 O/HCOOH 0.1% (v/v) and (B) MeOH/HCOOH 0.1% (v/v), and the separation was performed through a linear gradient: 0–1.0 min, 10% B (isocratic); 1.0–11.0 min, from 10% to 90% B (linear); 11.0–14.5 min, 90% B (isocratic); 14.5–15.0 min, from 90% to 10% B (linear); 15.0–18.0 min, 90% B (isocratic).…”

The products and by‐products of Olea europaea L.: olive fruits (primary agricultural product), oils (primary agro‐industrial product), pomaces (agro‐industrial processing by‐product), and leaves (agricultural practices by‐product), are promising sources of bioactive compounds. In the present study, qualitative and quantitative analyses of selected bioactive components in olive fruits, oils, and pomaces were performed. Total polyphenol content and antioxidant activity were analyzed in all samples (humid pomaces 2015: TPP, 26.0 ± 1.5–43.7 ± 3.0 g(GAEq)/kg DW; TEAC/ABTS, 189.5 ± 3.7–388.1 ± 12.0 mmol(Trx)kg DW). Radical (DPPH) quenching potential was analyzed via photometric and EPR methods, obtaining Vis/EPR signal ratio by 1.05 ± 0.45 and 1.66 ± 0.39 for fruits and pomaces, respectively. Through HPLC‐UV and HPLC‐MS/MS techniques, oleuropein and hydroxytyrosol, as well as selected hydroxycinnamic acids and flavonoids, were identified and quantified in olive fruits and pomaces. The main components were rutin, luteolin, and chlorogenic acid. Cytotoxic assay on fibroblast cells revealed toxic effects for selected extracts at highest tested concentrations (5%).

“…The tomato (Solanum lycopersicum L.; Lycopersicum esculentum L.) is the fruit of an herbaceous plant of the Solanaceae family. This widely consumed vegetable is high in antioxidants and other bioactive components, such as vitamins E and C, flavonoids (e.g., rutin), phenolic compounds (e.g., chlorogenic acid), carotenoids (β-carotene and lycopene) and glycoalkaloids (tomatine) [12][13][14][15]. Moreover, tomatoes are the main source of lycopene in the human diet.…”

Blood pressure control in hypertensive subjects calls for changes in lifestyle, especially diet. Tomato is widely consumed and rich in healthy components (i.e., carotenoids, vitamins and polyphenols). The aim of this study was to evaluate the chemical composition and antihypertensive effects of locular gel reconstituted in serum of green tomatoes of “Camone” variety. Tomato serum and locular gel were chemically characterised. The antihypertensive effects of the locular gel in serum, pure tomatine, and captopril, administered by oral gavage, were investigated for 4 weeks in male spontaneously hypertensive and normotensive rats. Systolic blood pressure and heart rate were monitored using the tail cuff method. Body and heart weight, serum glucose, triglycerides and inflammatory cytokines, aorta thickness and liver metabolising activity were also assessed. Locular gel and serum showed good tomatine and polyphenols content. Significant reductions in blood pressure and heart rate, as well as in inflammatory blood cytokines and aorta thickness, were observed in spontaneously hypertensive rats treated both with locular gel in serum and captopril. No significant effects were observed in normotensive rats. Green tomatoes locular gel and serum, usually discarded during tomato industrial processing, are rich in bioactive compounds (i.e., chlorogenic acid, caffeic acid and rutin, as well as the glycoalkaloids, α-tomatine and dehydrotomatine) that can lower in vivo blood pressure towards healthier values, as observed in spontaneously hypertensive rats.
