Aromatic plants contain natural antioxidant constituents such as phenolic compounds, which have attracted a great deal of public and scientific interest because of their health-promoting effects as antioxidants. Five plants, Filipendula ulmaria (meadow sweet), Crataegus monogyna (hawthorn), Polygonum aviculare (polygonum), Potentilla anserina (silverweed), and Pelargonium purpureum (little robi...

4 different plant species belonging to the same family mint (Mentha piperita), sage (Salvia officinalis), rosemary (Rosmarinus lavender (Lavandula angustifolia) were harvested from Afyon region. Total antioxidant and phenolic contents analyzed by DPPH Folin-Ciocalteu method. The effect of extra virgin olive oils oxidation stability was tested means rancimat According analysis results, M. piperi...

This study aimed to search for the optimum antioxidant mixture improvement of stability high-oleic sunflower oil. Seven antioxidants including vitamin E, phytic acid, bamboo leaves, rosemary extract, tea polyphenols, ascorbyl palmitate (AP) as well polyphenol (TPP) were used. Peroxide value, free radicals and Rancimat induction time results all proved that TPP was best single antioxidant. There...

Abstract A non-destructive fluorescence method combined with chemometric algorithms has been developed for discriminating between olive oils. The excitation-emission matrices (EEMs) of two oil varieties (Arbosana and Oliana) from crop seasons, which had undergone different irrigation treatments (control strategy regulated deficit (RDI)), were recorded. EEMs analysed using parallel factor analys...

In this chapter selected methods used in plant lipid analyses are discussed. The first step of fat analysis consists in the isolation of lipid components from the plant matrix, thus in the first section the most popular methods of isolation are described. Afterwards, due to the complicated mixture of lipid components their separation is required where different types of chromatography technique...
