A new dolabellane diterpene glycoside, named squoside A, and three new cycloartane glycosides, named squarrosides V, VI, and VII, have been isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.

    Chem Pharm Bull (Tokyo) 57(2):207-10 (2009) PMID 19182414

    Separation of ethyl acetate fractionation of Dracocephalum peregrinum afforded three new flavonoid glucosides (1-3), and a new cyanogenic glucoside (4). Their structures were elucidated based on HR-electron spray ionization (ESI)-MS, EI-MS, UV, IR, 1D-, and 2D-NMR data. 1-4 were tested in vitro for...

    The objective of the study was to evaluate the bitterness, grittiness and uniformity of drug loading as measures of the quality of 12 formulations of clarithromycin dry syrup (CAMDS), comprising one branded and 11 generic products. Some of the generic CAMDS formulations were more bitter than the bra...

    The binding of amines to artificial zinc-porphyrin receptors 1-4 was examined in basic aqueous solutions. For nicotinic acid and 3,5-dicarboxypyridine, substantial binding enhancements were observed compared to other amines with no pi system or carboxyl group. This observation suggested that interli...
