“…Considering the literature (Gurr et al, 2002), all our findings regarding the waste extracts (peels) are in accordance since the VLCSFA are mostly found in the cuticular surface layers of plant tissues; After exposure to thermal treatment, also the bioavailability of monounsaturated fatty acids (MUFAs) and saturated fatty acid (SFAs) (in the case of apple, no significant difference was reported) significantly increased (p<0.05) while unsaturated fatty acids decreased (Table 3). Comparing with the literature (Dulf et al, 2016), it can be stated that there is a partially accordance considering the literature reported decrease of polyunsaturated fatty acids (PUFAs), but also of MUFAs, after exposure to a fermentation process and an increase of SFAs. The explanation is based on the different types of treatment (thermal and fermentation) used within each study.…”

ABSTRACT80% of the grape harvest is used in the winemaking industry, resulting in huge amounts of waste which are still rich in phenolic compounds, while the same percentage of polyphenols are found in apple peel, whose total antioxidant capacity is five-to-six-fold higher than that of apple flesh. The aim of this research is the characterization of grape and apple peels waste, before and after the thermal treatment (10 minutes, 80°C), with respect to its bioactive compounds to evaluate their potential enhancement with respect to bioavailability. Based on the obtained results, the highest antioxidant activity and phenolic content was exhibited by thermally processed redgrape waste. After the thermal treatment, the caffeic acid 4-O-glucoside increased with a 27% in apple waste. As a conclusion, the grape and apple peels waste can be exploited for their bioactive compounds after the thermal process, whose bioavailability increased and can be added in food formulations as health promoting products.

“…Herbal and natural source of flavonoid and polyphenol compounds have been reported to act as scavengers of various oxidizing species (Dulf, Vodnar, & Socaciu, ). On the other hand according to the literature flavonoid compounds trap singlet oxygen and produce FLA‐O 2 compound (Majer, Neugart, Krumbein, Schreiner, & Hideg, ) (Figure b).…”

Anthracene as a chemical probe is usually used to trap the singlet oxygen and then detection and quantification can be based on absorbance. In this study, oxidation of anthracene declared that rate of singlet oxygen quenching in the presence of pasipay (passiflora incarnate L.) as a natural antioxidant, 1,4 Diazabicyclo [2.2.2] octane (DABCO) as a well‐known singlet oxygen scavenger and highly effective synthetic antioxidants in food industry such as Butylated hydroxytoluene (BHT), Butylated hydroxyanisole (BHA), tert‐Butylhydroquinone (TBHQ) decreased in the order of DABCO >pasipay > TBHQ > BHT > BHA. On the other hand, lipid photooxidation is the undesirable chemical process in which singlet oxygen result in the peroxidation of fatty acids. The results of this study also showed that oleic acid oxidation with singlet oxygen in the presence of pasipay (contains 0.4576 mg flavonoid compounds) diminished about 11% which shows pasipay has an effective role to inhibit lipid peroxidation.

Background: Since drug resistance has become one of the predominant problems of health worldwide, it is necessary to use new methods to combat drug-resistant bacteria. In this regard, medicinal plants are considered one of the richest sources to produce antibiotics. The aim of this study was to investigate the antibacterial effects as well as total phenolic and flavonoid contents of a number of medicinal plants collected from the Chaharmahal and Bakhtiari provinces of India, in order to investigate their potential use for the production of new antibiotics. Materials and Methods: In this experimental study, the maceration method was used to prepare hydroalcoholic extract of Medicago sativa, Onosma sericeum, Parietaria judaica L., Phlomis persica and Echinophora platyloba DC. The effect of these plants on Enterococcus faecalis (ATCC 29212) was investigated. To determine the antibacterial effect of the extracts, broth microdilution in sterile 96-well plate was used according to the McFarland standard (105 CFU/ml). The total phenolic content was assayed by using the Folin-Ciocalteu colorimetric method and expressed in terms of gallic acid equivalent. The total flavonoid content was assayed by aluminum chloride colorimetric method and expressed in terms of rutin equivalent. Results: Based on the results of this study, the 512, 256, 128, 32 and 32 µg/ml doses were determined to be the minimum inhibitory concentrations (MICs), and the 1024, 1024, 512, 128 and 128 μg/ml doses were derived as the minimum bactericidal concentration (MBCs) of M. sativa, O. Sericeum, P. judaica, P. persica and E. platyloba, respectively. E. faecalis and P. judaica contained the highest total phenolic content and flavonoid content, respectively. Conclusion: Given the comparatively higher antibacterial effect of P. persica and E. platyloba, as well as the presence of phenolic and flavonoid compounds in these plants, it is recommended that these plants be further investigated in feasibility studies for the production of new antibiotics.
