Advanced Research on the Antioxidant Activity and Mechanism of Polyphenols from Hippophae Species—A Review

Abstract

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.

Bioactive Compounds from Plant-Based Functional Foods: A Promising Choice for the Prevention and Management of Hyperuricemia

“…In recent years, with the increase in numbers of HUA patients, studies into the treatment of HUA using plant-based functional foods have received increasing attention. For example, sea buckthorn was found to exhibit high antioxidant capacity and XOD inhibition capacity, while lemon water extract can directly promote the metabolism of excess UA, thereby indicating a potential to treat HUA [34][35][36]. Previous studies have found that these functions are associated with the presence of large quantities of phytochemicals, which are chemical compounds originating from plants [37].…”

Effect of sea buckthorn meal extract in alleviating the toxic effect of ochratoxin A and zearalenone in porcine peripheral blood mononuclear cells

“…In this paper, we have demonstrated that the use of the sea buckthorn meal extract can improve some markers of the oxidative stress and inflammation altered by exposure to the mycotoxins ZEA and OTA. Sea buckthorn contains high concentrations of bioactive compounds as: vitamin C, carotenoids, tocopherols and polyphenols (flavonoids, phenolic acids and tannins) that are responsible for the antioxidant activity and antiinflammatory effect of the plant extract (Ji et al, 2020b) that are responsible for the SM beneficial activity observed in our study. This waste represents a promising biological method that can be used for the alleviation of the mycotoxins negative effects in farm animals.…”

“…Sea buckthorn (Hippophae rhamnoides) is a plant used in different fields as food, medicine and cosmetic industries (Ji et al, 2020a). The plant is rich in bioactive compounds as minerals, vitamins, unsaturated fatty acid, terpenoids, polyphenolic compounds, flavonoids, which have antioxidant and antiinflammatory effects (Zadernowski et al, 2005) .…”

Effect of storage time on biochemical characteristics and antioxidant activity of hawk tea (Litsea coreana) processed by boiling water fixation

“…A large number of studies have shown that polyphenols and flavonoids have strong antioxidant properties (Chen et al, 2020; Ji et al, 2020). It was found that the polysaccharide and flavonoid of hawk tea had good antioxidant activity (Chen et al., 2019; Tan et al, 2016; Xiao, et al 2017).…”
