“…Also, the seed extract LBS contained campesterol at a level of 8.07 ± 0.22 mg/100 g FW, which was several times higher than that of the petal extract LBP (1.24 ± 0.02 mg/100 g FW) (Table ) and some vegetable seeds such as pepper seeds (4.23–5.41 mg/100 g FW) and tomato seeds (1.08–6.56 mg/100 g FW) (Silva et al ., ; Ancos et al ., ). However, the levels of stigmasterol in butterfly pea seeds and petals were similar (7.95 ± 0.63 and 6.70 ± 0.83 mg/100 g FW, respectively) (Table ) and approximately five and eight times higher than in berryfruit (0.50–1.60 mg/100 g FW) and pepper seeds (0.63–0.93 mg/100 g FW) (Silva et al ., ; Salvador et al ., ). Phytosterols were confirmed to possess hypocholesterolaemic function and reduce the risks of benign prostatic hyperplasia, cardiovascular diseases, colon and breast cancer development, as well as immunological effects in macrophages (Hamedi et al ., ).…”

Summary The hydrophilic phenolics, lipophilic tocopherols, phytosterols and fatty acids in butterfly pea seeds and petals were determined. The seeds had fifteen phenolics; of them, sinapic acid, epicatechin and hydroxycinnamic acid derivative concentrations were above 0.5 mg g−1. The petals contained a group of ternatins, flavone glycosides and delphinidin derivatives. Both the seeds and petals had four phytosterols and α‐ and γ‐tocopherols. However, the level of β‐sitosterol or γ‐tocopherol in the seeds was much higher than in the petals. Linoleic acid was the most abundant fatty acid in the seeds and petals, while phytanic acid was found in the petals. The effect of lipophilic and hydrophilic extracts of the seeds [lipophilic extract of the butterfly pea seeds (LBS) and hydrophilic extract of butterfly pea seeds (HBS)] and petals [lipophilic extract of the butterfly pea petals (LBP) and hydrophilic extract of butterfly pea petals (HBP)] on decreased HEp‐2 human carcinoma cell viability was evaluated. The effect of HBS or HBP on decreased cancer cell viability was much higher than that of either LBS or LBP, while HBS showed significantly higher effect than HBP. The results indicated that butterfly pea seed and petal extracts could have the potential in functional food development.

“…Although novel non-thermal technologies can also have an effect on the concentration of health-promoting compounds such as anthocyanins, overall, results obtained so far suggest that if a loss of phytochemicals is produced after non-thermal processing, this would be smaller compared to that obtained after a traditional thermal treatment (Marszałek, et al, 2015b;Marszałek, Woźniak, Kruszewski, & Skąpska, 2017). The phytochemical content and quality of fresh and processed strawberries depends on several factors including season, maturity, variety, and processing conditions including treatment intensity and duration (Ban, et al, 2018;Oszmiański, Lachowicz, Gorzelany, & Matłok, 2018;Salvador, Rocha, & Silvestre, 2015;Šamec, Maretić, Lugarić, Mešić, Salopek-Sondi, & Duralija, 2016;Xie, et al, 2015). This has to be calculated for each process independently and needs to be considered when calculating the dietary intake of these compounds from processed strawberries and strawberry-based products.…”

Strawberries are one of the most important fruits in the Mediterranean diet and have been widely investigated for their nutritional and nutraceutical properties. Concern about the safety of fresh and processed strawberries has increased in recent years due to the emergence of several outbreaks of foodborne pathogens linked to their consumption. The use of chlorine as a disinfectant has been identified as a concern due to public health issues and limited efficacy at removing contamination, and preventing crosscontamination. This has led to the development of novel alternatives to chlorine disinfection and thermal treatments, which include, among others, the use of organic acids, high pressure processing, intense pulsed light, or pulsed electric fields. These technologies do not generally affect the nutritional and organoleptic properties of the product and some of these have been reported to stimulate the production of valuable compounds in strawberries and to improve their overall quality.

“…It contains nearly four times the anthocyanins as compared to other commonly consumed berries. Elderberries are reported to include several bioactive compounds, both phenolic compounds like anthocyanin derivatives, including cyanidin 3-glucoside, cyanidin 3-sambubioside, cyanidin 3-sambubioside-5-glucoside and cyanidin 3,5-diglucoside [27][28][29] and triterpenic compounds such as ursolic and oleanolic acids and sterols such as β-sitosterol [30,31].…”

The aim of this study is to estimate the influence of polyphenolic compounds, renin inhibitors (Aliskiren) and their association on clinical and biochemical parameters, on an experimental model of arterial hypertension (AHT). The combination of Aliskiren and polyphenolic extract has the effect of reducing systolic and diastolic blood pressure. Experimental data highlight the hypocholesterolemic, antiatheromatous, hypolipidemic and cardioprotective effects of polyphenolic extracts. The results demonstrate a significant decrease in the measured biochemical parameters of the oxidative stress (unspecific-ceruloplasmin, uric acid and enzyme-GSH-Px and SOD) of the groups treated with polyphenolic extracts. In the polyphenolically protected AHT group there are statistically significant differences compared to the AHT group, regarding the platelet adhesion index. Aliskiren has more evident vascular protective effects when associated with polyphenols in the experimental AHT compared to unprotected hypertensive group. The antioxidant properties of anthocyanins, combined with the vascular properties of these substances, recommend them as promising therapeutic agents in the prevention/therapy of cardiovascular disorders in general and of AHT in particular. The characterization of polyphenolic extracts, as well as the studies on biocompatibility, will constitute the baseline for understanding the mechanisms, by which phytopreparations can be used for preventive or adjuvant therapeutic purposes.
