A direct current (DC) polarographic assay based on the decrease of anodic current of HydroxoPerhydroxoMercury (II) Complex (HPMC) formation in H2O2 solution in Clark Lubs (CL) buffer (pH 9.8) as working solution was previously applied to determine antioxidant (AO) capacity of water‐soluble compounds. Here, the applicability of HPMC assay was extended into samples poorly soluble in water such as the...
The chemical composition and aroma profile of seven Rosa damascena Mill. essential oil samples from Saudi Arabia (Al‐Shafa, Al‐Hada and Al‐Taif area) were studied in details by means of gas chromatography‐mass spectrometry (GC/MS) and gas chromatography with flame ionization detection (GC‐FID). As a result, more than 120 compounds, containing C3‐C27 carbon atoms, mainly mono‐ and sesquiterpenoids,...
