Significantly, both acyl glucuronides, but not the aglycones, caused a concentration-dependent decrease in the transfection efficiency of the DNA, with a greater than 80% decrease in phage survival produced by the 5 mM concentrations of the glucuronides. No increase in lacZa mutations accompanied...
The acid catalysed rearrangement of asperulosidol 5 leads to the tetracyclic acetal 7 whose structure and configuration has been determined by 1H-NMR and 13C-NMR spectroscopy, as well as by the Li/NH3 reduction of 7 to the cyclopententriol 10. The reaction course has been clarified by ...

The dichloromethane extract of Hymenoxys lemmonii afforded 13 sesquiterpene lactones, including four known and two new aglycones and two known and five new glycosides. Of the latter seven compounds, one is a glucoside and six are 6′-acetylglucosides. Structures of all compounds were established ...
flavones, mass spectrometry, flavonoids, gas chromatography, arnica alpina, ArnicaGas chromatographic analysis of 51 flavonoid aglycones allowed a quantification of structural influences on retention time. Well-reproducible structure-retention increments were calculated. These can be valuable for the analysis...
