“…A study by Carmen et al also reported high antioxidant levels in the stems and leaves of AC upon measuring lipid peroxidation and scavenged free radicals after arsenic exposure [ 34 ]. AC exhibited a low level of thiobarbituric acid reactive substances (TBARS), typical oxidative stress markers, and a higher level of scavenged DPPH radicals under arsenic-exposed conditions.…”

“…The total phenolic content of the AC extract was examined based on the Folin-Ciocalteu colorimetric method [ 24 ]. Briefly, either standard gallic acid (6.25–100 µg/mL) or plant extract, was reacted with 1M Folin-Ciocalteu reagent for 15 min.…”

“…AC tea and tincture are also widely known as abundant sources of antioxidants and phytoflavanoids [ 23 ]. Preliminary analysis of the phytochemical composition of the ethanolic extracts of AC showed that they included tannins, steroids, coumarins, flavonoids, and phenols [ 24 ]. In addition, the isolation of active compounds from AC extracts have resulted in the identification of sesamin and asarinin [ 22 ]; meanwhile, the most abundant volatile components of AC essential oil were shown to be methyl eugenol (57%), α-pinene (11.7%), elemicin (13.2%), and piperitone (16.2%) [ 23 ], which have been well studied for their antioxidant and anti-aging properties [ 25 , 26 , 27 ].…”

Long-term exposure of the skin to solar radiation causes chronic inflammation and oxidative stress, which accelerates collagen degradation. This contributes to the formation of wrinkles and dark spots, skin fragility, and even skin cancer. In this study, Anemopsis californica (AC), a herb from North America that is well known for treating microorganism infection and promoting wound healing, was investigated for its photoprotective effects. The biological effects of AC were studied on two in vitro models, namely, lipopolysaccharide (LPS)-induced macrophages and ultraviolet B (UVB)-irradiated dermal fibroblasts, to characterize its underlying molecular mechanisms. The results showed that AC decreased the mRNA levels of inflammatory mediators in sensitized macrophages, including cytokines, inducible nitric oxide synthase (iNOS), and cyclooxygenase (COX-2). Moreover, AC alleviated UVB-induced photoaging in dermal fibroblasts by restoring procollagen synthesis. This resulted from the regulation of excessive reactive oxygen species (ROS) by AC, which was mediated by the activation of the antioxidative system nuclear factor erythroid 2-related factor 2 (NRF2). AC also alleviated oxidative stress and inflammatory responses by inhibiting the phosphorylation of mitogen-activated protein kinase (MAPK) and interfering with the nuclear translocation of the immune regulator nuclear factor of activated T-cells 1 (NFATc1). In conclusion, the protective effects of AC on skin cellular components suggested that it has the potential for use in the development of drugs and cosmetics that protect the skin from UVB-induced chronic inflammation and aging.

“…This characteristic is related to the activation of cellular defense mechanisms. Often, when under stressful conditions, there is an increased production of reactive oxygen species (ROS) and consequent oxidative damage to cell structures (Del-Toro-Sánchez et al 2013;Liu et al 2018a). In this context, the capacity of plants to cope with stress as well as the choice of plant species for phytoremediation has been related to their ability to activate antioxidant systems (Gomes et al 2013Gomes and Juneau 2016).…”

Phytoremediation is an eco-friendly and economical technology in which plants are used for the removal of contaminants presents in the urban and rural environment. One of the challenges of the technique is the proper destination of the biomass of plants. In this context, the use of ornamental plants in areas under contamination treatment improves landscape, serving as a tourist option and source of income with high added value. In addition to their high stress tolerance, rapid growth, high biomass production, and good root development, ornamental species are not intended for animal and human food consumption, avoiding the introduction of contaminants into the food web in addition to improving the environments with aesthetic value. Furthermore, ornamental plants provide multiple ecosystem services, and promote human well-being, while contributing to the conservation of biodiversity. In this review, we summarized the main uses of ornamental plants in phytoremediation of contaminated soil, air, and water. We discuss the potential use of ornamental plants in constructed buffer strips aiming to mitigate the contamination of agricultural lands occurring in the vicinity of sources of contaminants. Moreover, we underlie the ecological and health benefits of the use of ornamental plants in urban and rural landscape projects. This study is expected to draw attention to a promising decontamination technology combined with the beautification of urban and rural areas as well as a possible alternative source of income and diversification in horticultural production.

“…Elevated levels of ROS can damage proteins, nucleic acids and lipids, and may even contribute to the death of cells (Del-Toro-Sanchez et al, 2013;Gao et al, 2010). In response, as part of their nonenzymatic antioxidant systems, plants have developed mechanisms to control their levels of reactive oxygen molecules, by producing higher concentrations of compounds such as ascorbate, glutathione, phytochelatines, phenols and flavonoids.…”
