and studies of alpha glucosidase inhibition and antifungal activity of husk.

The coffea husk, a protected agricultural crop, is abundant in Vietnam. Examining the effects of husk compounds on α-glucosidase and antifungal drug activity was the primary objective of this research. A cholestane-type steroid, coffeacanol A (1), was extracted from the ethyl acetate extract.

Harnessing potassium peroxymonosulfate activation of WO/diatomite composites for efficient photocatalytic degradation of tetracycline.

The increasing prevalence of pharmaceutical contaminants in aquatic ecosystems poses profound challenges for both environmental sustainability and public health. Addressing this pressing issue requires the development of innovative, cost-effective, and efficient remediation approaches. Here we report the synthesis of WO/diatomite composites and their photocatalytic degradation in conjunction with potassium peroxymonosulfate (PMS) activation.

Straightforward electrochemical synthesis of a CoO nanopetal/ZnO nanoplate p-n junction for photoelectrochemical water splitting.

Hydrogen production through photoelectrochemical (PEC) reactions is an innovative and promising approach to producing clean energy. The PEC working electrode of a CoO/ZnO-based p-n heterojunction was prepared by a straightforward electrochemical deposition with different deposition times onto an FTO (Fluorine-doped Tin Oxide) glass substrate. The successful synthesis of the materials was confirmed through analysis using XRD, FTIR, SEM-EDX, DRS, and PL techniques.

and docking and molecular dynamic of antimicrobial activities, alpha-glucosidase, and anti-inflammatory activity of compounds from the aerial parts of .

Twelve compounds were isolated from aerial parts through phytochemical analysis and the genus is the first place where the compounds 4-6 and 11-12 have been found. Based on the ability to inhibit NO production in RAW264.7 cells, compound 2 has demonstrated the strongest anti-inflammatory activity with an IC of 7.

Antimicrobial and alpha-glucosidase inhibitory flavonoid glycosides from the plant : and approaches.

Seven flavonoid glycosides were isolated from the aerial portions of during a phytochemical analysis. This comprised one novel component, ecurvoside, and six well-studied compounds, namely astragalin, isoquercitrin, nicotiflorin, rutin, hesperidin, and neohesperidin. The chemical structures of compounds were identified using spectroscopic techniques and a comparison with previously published studies.

anti-inflammatory, molecular docking and molecular dynamics simulation of oleanane-type triterpenes from aerial parts of .

Bioactive-guided investigation of the aerial parts of Naiki, Tagane, and Yahara (Rubiaceae) led to the isolation of four triterpenes, including two new triterpenes recurvatanes A and B (1 and 2), along with two known compounds 3β,6β,23-trihydroxyolean-12-en-28-oic acid (3) and 3β,6β,19α,23-tetrahydroxyolean-12-en-28-oic acid (4). The chemical structures of the compounds were identified from spectroscopic data and by comparison with the literature. A comprehensive review of NMR data of the oleanane-type triterpenes bearing 3-hydroxy and 4-hydroxymethylene groups indicated the characteristic spectroscopic features in this series.

Supercritical CO assisted extraction of essential oil and naringin from peel: antimicrobial activity and docking study.

The extraction of bioactive compounds, including essential oils and flavonoids, using organic solvents is a significant environmental concern. In this work, waste peel was the ingredient used to extract essential oil and naringin by conducting a supercritical CO technique with a two stage process. In the first stage, the extraction with only supercritical CO solvent showed a significant enhancement of the d-limonene component, up to 95.
