The chemical investigation of the methanol trunk bark extract of led to the isolation of a new flavanone, 5,7,4'-trihydroxy-3',5'-bis(3-methylbutadienyl)flavanone (trivially named senegalensisnone) (), together with seven known compounds, abyssinone-V-4'--methyl ether (), abyssinone V (), Calopocarpin (), genistein ) mixture of stigmasterol () and -sitosterol () and -sitosterol-3---D-glucopyranoside (). The structures of the isolates were elucidated by extensive spectroscopic and spectrometric analyses (1D and 2D NMR, ESI-MS) and by comparison with previously reported data. The absolute configuration of was deduced based on comparison of its experimental CD with that of similar compound. All the compounds were tested for their antibacterial, antifungal and antioxidant activities. Compound displayed weak antibacterial activity against with MIC value of 62.5 g/mL. All the isolates were found to be inactive as antioxidant agents in the DPPH, ABTS and FRAP assays.

A comparative metabolomic study of three varieties of wild Rosa (, , and ) from a Kamchatka expedition (2024) was conducted via extraction with supercritical carbon dioxide modified with ethanol (EtOH), and detection of bioactive compounds was realized via tandem mass spectrometry. Several experimental conditions were investigated in the pressure range 50-350 bar, with the used volume of co-solvent ethanol in the amount of 2% in the liquid phase at a temperature in the range of 31-70 °C. The most effective extraction conditions are the following: pressure 200 Bar and temperature 55 °C for ; pressure 250 Bar and temperature 60 °C for ; pressure 200 Bar and temperature 60 °C for .

Six novel compounds, comprising three quinolones (1a, 1b, and 2) and three flavanones (3-5), along with seven known analogs (6-13), were isolated from the 95% EtOH extract of the stems and leaves of Glycosmis craibii var. glabra. The structures of the new compounds were elucidated using HR-ESI-MS, UV, and 1D and 2D nuclear magnetic resonance (NMR) data analysis.
