Dermal aging is characterized by states of oxidative stress, chronic inflammation, and abnormal proteolytic degradation due to the action of hydrogen peroxide, superoxide, 5-lipoxygenase, and elastase, respectively. Noteworthy elastase inhibition has previously been reported, and so this study aimed
We synthesized silver nanoparticles using thirty Chinese plant extracts via a green synthetic strategy. UV-visible spectra showed that the silver nanoparticles have an absorbance at 450 nm. Among the thirty extracts, seven extracts (Cratoxylum formosum, Phoebe lanceolata, Scurrula parasitica,
Rapanone (2,5-dihydroxy-3-tridecyl-1,4-benzoquinone), a natural compound isolated from Myrsine guianensis growing in the Andean highlands of Colombia, was studied in different in vitro and in vivo models as a potential antioxidant and anti-inflammatory drug. Rapanone showed a mild
Rapanea ferruginea antioxidant and antitumoral properties were not explored before in literature. This study aimed to investigate these biological activities for the R. ferruginea leaf extract and correlate them with its phenolic content and influence in biological membrane dynamics. Thus, in this
The cape myrtle, Myrsine africana L., is a widely used medicinal plant, which has not been well investigated. We assessed the in vivo hepatoprotective and in vitro antiproliferative and antioxidant effects of leaf extracts of M. africana chemically profiled using high-performance liquid
Bioassay-guided fractionation of the methanol extract of the shoots of Myrsine africana led to the isolation of the new compound myricetin 3-O-(2″,4″-di-O-acetyl)-α-l-rhamnopyranoside (9) and 11 known compounds. The known compounds quercetin 3-O-(3″,4″-di-O-acetyl)-α-l-rhamnopyranoside (8), rutin
