Abstract:
... Volatile constituents of beechwood creosote were determined using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The major volatile constituents of creosote were 2-methoxyphenol (guaiacol; 25.2%) 2-methoxy-4-methylphenol (4-methylguaiacol; 21.4%), 3-methylphenol (m-cresol; 8.3%) 4-methylphenol (p-cresol; 7.9%) 2-methylphenol (o-cresol; 4.6%) and phenol (2.8%). The antiox ...

Abstract:
... Flavonol glycoside composition and content in blueberry and blackberry extracts were determined using a high-performance liquid chromatographic (HPLC) separation method coupled with photodiode array (PDA) and mass spectrometric (MS) detection. The hydrophilic antioxidant capacities of crude and fractionated flavonol extracts were also determined by the oxygen radical-absorbing capacity (ORAC(FL)) ...
