GntherAbstractBlood serum is commonly used for clinical diagnostics because its protein composition bears wealth of information about the health of an organism. Here we have compared different protocols for the separation of proteins and metabolites, including precipitation methods and ultrafiltration. This is the first report on the analysis of podophyllotoxin and its derivatives from Linum species were compared. We also describe new method to recover the hydrophobic fraction for ultrafiltration with good reproducibility.

In the second approach, the extraction of the fungicides from the soil samples was conducted using acetone as organic solvent which was then diluted with water to give 5 vv content. The method was applied in the regular monitoring of Closantel residues in milk by highperformance liquid chromatography with fluorescence detectionJournal of Chromatography Volume 846, Issues 12, Pages 383386G. The recovery was 9699 after one extraction. The glycosidasemethod showed the best result with respect to the accuracy studies the acetonemethod has an advantage compared to the other methods due to its capability to calculate the aglycone, lignan glycoside and total lignan.

Lambropoulou, Triantafyllos The performance of the method was found to be acceptable, when tested by three consecutive boiling water extractions from carrot samples with different levels of 6methoxymellein. Bengtsson, Grete Skrede, Gjermund VogtAbstractBy modification and combination of existing methods we have developed rapid method for quantification of 6methoxymellein in carrot roots by means of boiling water and solid phase extraction, followed by high performance liquid chromatography HPLC. scabrinerve Davis were determined. Repeatability was between and 14. 2 and the limits of detection between and 3ngg1.

The method was applied in the regular monitoring of Closantel residues in milk by highperformance liquid chromatography with fluorescence detectionJournal of Chromatography Volume 846, Issues 12, Pages 383386G. Here we have compared different protocols for the separation of proteins and metabolites, including precipitation methods and ultrafiltration. The pesticides were isolated with fused silica fiber coating with 85m polyacrylate. With this method it was possible for one person to extract samples during working day and further quantify the amount of 6methoxymellein by automatic HPLC the following night.
