nsufficient innovative research on the sequestration of Cr(VI) from the aquatic ecosystem has made Cr(VI) a recalcitrant water contaminant that often affects water sources. In this work, a novel plant anchor-nanocomposite was fabricated from the spent molecular sieve, multi-walled carbon nanotubes, and the extract from the stem bark of . It was envisaged that due to the phytochemical constituent of the modifier, this nanocomposite could also act as potent adsorbents for the treatment of Cr(VI) polluted water. To the best of our knowledge, the application of stem bark extract as a modifier for the green fabrication of nanocomposite has not been reported. The resulting composites showed good uptake capacity for Cr(VI) as well as efficient reusability.

Alders are widely distributed riparian trees in Europe, North Africa and Western Asia. Recently, a strong reduction of alder stands has been detected in Europe due to infection by species (Stramenopila kingdom). This infection causes a disease known as alder dieback, characterized by leaf yellowing, dieback of branches, increased fruit production, and bark necrosis in the collar and basal part of the stem.

In the present study, 85% aqueous ethanol extract of stem bark (MESB) showed the isolation of six bioactive compounds including myricanone (), myricanol-5-O-β-D-glucopyranoside (), myricetin (), myricolol (), β-sitosterol (), and β-sitosterol-D-glucoside (). The HPLC approach revealed as a key bioactive compound, with a 69% abundance in the crude ethanol (CE) extract. Furthermore, the CE was assessed for antioxidant activity using DPPH and hydroxyl radical tests, while purified compounds were examined for total antioxidant capacity using cyclic voltammetry and verified using the density functional theory (DFT) method.

The expression of matrix metalloproteinase (MMP)-7 is reported to be correlated with invasion and metastasis of colorectal cancer (CRC). Therefore, the inhibition of MMP-7 would be beneficial for the suppression or prevention of CRC cell invasion and metastasis. The stem bark of Acanthopanax senticosus, a widely used medicinal herb, contains isofraxidin (IF) and chlorogenic acid (CGA) as major components.

is a medicinal plant of which bark decoctions are used in traditional medicine for the treatment of diarrhea symptoms in Gabon. The aim of the present work was to perform phytochemical and pharmacological analyses of decoctions of bark. In a principal approach, spectrophotometric analyses were used to quantify phenolic compounds, followed by liquid chromatography coupled to mass spectrometry analysis that allowed the identification of flavanone-flavone dimers as the main metabolites.
