“…These include minerals, vitamins, polysaccharides, unsaturated fatty acid, terpenoids, polyphenolic compounds, nonsteroidal compounds, flavonoids, organic acids and volatile components, which have antioxidant, anti-inflammatory, anti-radiation and curative effects on burns and ulcers [6,7]. Polyphenols are secondary plant metabolites, arising from phenylalanine or shikimic acid, playing a pivotal role in counteracting various type of stress, other than contributing to the organoleptic properties of plants and plant-derived food [8]. In addition, it is well known that polyphenols exert beneficial effects upon human health, due to their antioxidant, anti-inflammatory, cardioprotective, anticancer and antimicrobial properties [9,10].…”

Oxidation is a normal consequence of metabolism in biological organisms. The result is the formation of detrimental reactive oxygen species (ROS) and reactive nitrogen species (RNS). A large number of studies have shown that polyphenolic compounds have good antioxidant properties. Hippophae species plants have high polyphenolic content and are widely used in food, medicinal, or the cosmetic field. The main polyphenols in Hippophae species are flavonoids, phenolic acids and tannins, which have multiple effects. However, there is a limited number of studies on polyphenols in Hippophae species plants. This review systematically summarizes the polyphenols compounds and antioxidant activity of Hippophae species plants, and it is noteworthy that the main mechanisms of the polyphenols of Hippophae with antioxidant activity have been summarized as follows: regulating enzyme activity, affect the antioxidant reaction of cells, and others. This review provides useful information for the further study and application of Hippophae species polyphenols and their antioxidant activity.

“…Antioxidant capacity of phenolic compounds extracted from OMW and OP has been studied in several investigations. Di Mauro et al () reported that antioxidant activity of OMW was higher than hydroxytyrosol, because of the synergistic effect of other phenolics in OMW. Cioffi et al () found that antioxidant activity of OP in DPPH test was lower than olive oil and olive leaf extract in relation to its total phenolic content.…”

“…Cioffi et al (2010) found that antioxidant activity of OP in DPPH test was lower than olive oil and olive leaf extract in relation to its total phenolic content. Moreover, different extraction techniques have been used to prepare extracts and several purification or fractionation methods have been employed to extract the individual phenolic compounds (Cioffi et al, 2010;Dejong & Lanari, 2009;Di Mauro et al, 2017;Farag, Mahmoud, & Basuny, 2007;Orozco-Solano, Priego-Capote, & Luque de Castro, 2011). Also, the effects of these extracts on the oxidative stability of oils, fats, and foods as an antioxidant have been investigated (Caporaso et al, 2017;Dejong & Lanari, 2009;Fki, Allouche, & Sayadi, 2005;Orozco-Solano et al, 2011;Sánchez de Medina et al, 2012).…”

In this study, the effects of olive mill wastewater (OMW) and olive pomace (OP) extracts (1 and 2 mg/g), lecithin (L, 1–5 mg/g), and ascorbyl palmitate (AP, 0.2 mg/g) on the oxidative stability of refined sunflower oil (SFO) and its purified triacylglycerols (TAGs) were investigated under accelerated oxidation conditions. Induction period of TAGs increased from 6.84 to 11.27 hr, with OMW methanol extract (1 mg/g), while OP extracts provided less protection (9.79 hr) at 90°C in Rancimat. The K232 values of the SFO with extracts (1 mg/g) and AP (0.2 mg/g) was lower than those of butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), and α‐tocopherol containing oil samples at 60°C. Binary combinations of extracts with AP (0.2 mg/g) or L (5 mg/g) also effectively decreased the K232 and K270 values of TAGs during oxidation. In conclusion, OMW and OP extracts can be synergistically used with L or AP for stabilization of SFO against oxidation. Practical applications Generally, edible oils contain high amount of unsaturated fatty acids which are susceptible to oxidation during heat required food processes. Natural antioxidants are preferably used for increasing oxidative stability of edible oils. Olive mill byproducts contain valuable phenolic compounds that have high antioxidant capacity. In this study, we studied antioxidant efficiencies of the olive wastewater and pomace extracts in sunflower oil in combinations with lecithin and ascorbyl palmitate. These combinations can be successfully used to increase the oxidative stability of sunflower oil.

Antiproliferative, Antimicrobial, and Antifungal Activities of Polyphenol Extracts from Ferocactus Species

Polyphenols, obtained from natural resources, may possess important pharmacological effects. The polyphenolic profiles of the stem extracts of six Ferocactus species (sp.): F. gracilis, F. pottsii, F. herrerae, F. horridus, F. glaucescens, and F. emoryi, were measured using high-performance liquid chromatography (HPLC) with diode-array detection (DAD). Additionally, anticancer, antibacterial, and antifungal activities were examined. Results showed the presence of high to moderate amounts of polyphenols in the extracts (phenolic acids: Protocatechuic acid, 3,4-dihydroxyphenylacetic acid, caffeic acid, and vanillic acid; flavonoids: Rutoside and quercitrin). The highest amounts of 3,4-dihydroxyphenylacetic acid were found in F. glaucescens ((132.09 mg 100 g−1 dry weight (DW)), F. pottsii (75.71 mg 100 g−1 DW), and F. emoryi (69.14 mg 100 g−1 DW) while rutoside content was highest in F. glaucescens (107.66 mg 100 g−1 DW). Maximum antiproliferative activities were observed against HeLa and Jurkat cancer cells, with F. glaucescens, F. emoryi, and F. pottsii showing the highest anticancer activity. Most bacteria were sensitive to Ferocactus sp. stem extracts. Escherichia coli and Staphylococcus aureus were the most sensitive. Excellent antifungal effects were observed against Aspergillus ochraceus and A. niger. However, Penicillium funiculosum, P. ochrochloron, and Candida albicans were relatively resistant. This is the first study reporting novel sources of polyphenols in Ferocactus sp. with anticancer and antimicrobial activities.
