Laurel Extracts Obtained by Steam Distillation, Supercritical Fluid and Solvent Extraction
The chemical composition of laurel leaves and fruits essential oils (content of 0.917 and 0.747%, respectively) and laurel leaves extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC-MS. The predominant compound in the essential oils and in CO2 extracts obtained at pressures/temperatures of 100 bar/40°C and 250 bar/40°C was 1,8-cineole...
متن کاملNew method for determining total dietary fiber by liquid chromatography.
The molecular weight limit of water-soluble dietary fiber (SDF) determined by the Prosky method was studied by liquid chromatography (LC). It was confirmed that only SDF with an average degree of polymerization of 12 or higher can be determined by the Prosky method. Total dietary fiber (TDF) was determined by 2 additional methods using LC. In the first method, the total quantity of insoluble di...
متن کاملSeparation and identification of volatile constituents in Artemisia argyi flowers by GC-MS with SPME and steam distillation.
Artemisia argyi leaf is a widely used traditional Chinese medicine (TCM). In this work, for the first time, the separation and identification of volatile constituents in Artemisia argyi flowers is performed. Gas chromatography-mass spectrometry (GC-MS) with solid-phase microextraction (SPME) is developed for the fast analysis of volatile constituents in the flowers. Several headspace SPME param...
متن کاملCorrespondence: A method for determining total nitrogen...
The digestion method using a small proportion of a strong oxidizing agent perchloric acid seems to have been taken from a ’continuous flow method’, which was not designed for discrete digestion and analysis. There is considerable evidence that satisfactory digestion ofeven tMrly refractory substances can be achieved without the use of perchloric acid (1) and it is now usually recommended that p...
