Pavlovic, Radmila published the artcileEffectiveness of different analytical methods for the characterization of propolis: a case of study in Northern Italy, HPLC of Formula: 140-11-4, the main research area is propolis phenol flavone radical scavenger HPLC GC MS; HPLC–Q-Exactive-Orbitrap®–MS analysis; phenolic glycerides; poplar; propolis.
Propolis is used as folk medicine due to its spectrum of alleged biol. and pharmaceutical properties and it is a complex matrix not still totally characterized. Two batches of propolis coming from two different environments (plains of Po Valley and the hilly Ligurian-Piedmont Apennines) of Northern Italy were characterized using different anal. methods: Spectrophotometric anal. of phenols, flavones and flavonols, and DPPH radical scavenging activity, HPLC, NMR, HSPME and GC-MS and HPLC-MS Orbitrap. Balsam and moisture content were also considered. No statistical differences were found at the spectrophotometric anal.; balsam content did not vary significantly. The most interesting findings were in the VOCs composition, with the Po Valley samples containing compounds of the resins from leaf buds of Populus nigra L. The hills (Appennines) samples were indeed characterize by the presence of phenolic glycerides already found in mountain environments. HPLC-Q-Exactive-Orbitrap-MS anal. is crucial in appropriate recognition of evaluate number of metabolites, but also NMR itself could give more detailed information especially when isomeric compounds should be identified. It is necessary a standardized evaluation to protect and valorize this production and more research on propolis characterization using different anal. techniques.
Molecules published new progress about Balsams Role: BSU (Biological Study, Unclassified), BIOL (Biological Study). 140-11-4 belongs to class esters-buliding-blocks, name is Benzyl acetate, and the molecular formula is C9H10O2, HPLC of Formula: 140-11-4.
