Comparative ¹H NMR Metabolomics Between Scandinavian Propolis and Australian Propolis: The Quest to Identify Radical Scavenging Compounds. [PDF]

Magn Reson Chem
Propolis from Scandinavia and Australia was chemically characterized using 1H NMR spectroscopy and multivariate modeling. Recursive partial least squares revealed spectral features associated with radical scavenging activity, and STOCSY enabled identification of the key phenolic compounds underlying these bioactive features. ABSTRACT Propolis from Apis
