Unlabelled: This study investigated the potential of sauce meeting the functional labeling system (TSF) with resistant maltodextrin on muscle atrophy using dexamethasone-induced C2C12 myotubes and hindlimb immobilization (HI)-induced C57BL/6J mice. TSF significantly improved cell viability, myotube diameter, and fusion index in C2C12 myotubes. Furthermore, TSF effectively mitigated HI-induced muscle atrophy in mice, enhanced grip strength, and increased muscle mass.

Anderss (Salicaceae), commonly referred to as Korean willow, is native to East Asia, particularly Korea and China, and it has been used in traditional Korean folk medicine for its potent anti-inflammatory, analgesic, and antioxidant properties. In our ongoing research efforts to discover biologically new natural products, phytochemical analysis on an ethanolic extract of twigs yielded the isolation and identification of ten phenolic compounds (-), including a newly discovered phenolic glycoside () named isograndidentatin D, isolated via HPLC purification. The structure of compound was determined through extensive 1D and 2D NMR spectral data analysis and high-resolution electrospray ionization mass spectrometry (HR-ESIMS).

Phytochemical analysis of the methanolic extracts of Jatropha podagrica stalks and roots using liquid chromatography-mass spectrometry (LC-MS) led to the isolation of six compounds: corchoionoside C (1), isobiflorin (2), fraxin (3), hovetrichoside C (4), fraxetin (5), and corillagin (6). The isolated compounds (1-6) were tested for their cytotoxicity against MDA-MB-231 human breast cancer cells. Remarkably, compound 4 (hovetrichoside C) exhibited robust cytotoxicity against MDA-MB-231 cells, displaying an IC value of 50.

(), the "weeping willow," has been used in traditional Korean medicine to treat pain and fever due to its high concentrations of salicylic acid and salicin. The present study investigated bioactive compounds from twigs to discover bioactive natural products. Phytochemical investigation of the ethanol (EtOH) extract of twigs followed by liquid chromatography-mass spectrometry (LC/MS)-based analysis led to the isolation of two salicin derivatives, salicortinol and salicortin, the structures of which were determined by interpretation of their NMR spectra and data from the LC/MS analysis.

(Salicaceae) is a willow tree and has been used as a medicinal herb in Korea to treat pain and fever. As a part of an ongoing study to identify bioactive natural products, potential anti-adipogenic compounds were investigated using the ethanol (EtOH) extract of twigs. Phytochemical investigation of the EtOH extracts using liquid chromatography-mass spectrometry (LC/MS) led to the separation of two compounds, oregonin () and 2'--acetylsalicortin ().
