Currently, he is associate professor in pharmacognosy at the Institute of Pharmaceutical Sciences, University of Graz. He performed postdoctoral studies at the School of Pharmacy, University of London, studying alkaloids and flavonoids, and at Uppsala University for anti-inflammatory bioassays. Selected work published between 2008 and mid-2012 is covered.įranz Bucar studied pharmacy at the University of Graz, Austria, where he also received his doctoral degree in natural sciences. Methods for proper identification of plant material, problems of post-harvest changes in plant material, extraction methods including application of ionic liquids, de-replication procedures during natural product isolation are further issues to be discussed by the review. Special attention is given to chiral stationary phases in isolation of natural products. Furthermore, examples of using different preparative solid-phase extraction (SPE) columns including molecular imprinting technology have been included. Although methods described earlier like the liquid-solid chromatographic techniques (VLC, FC, MPLC, HPLC) or partition chromatographic methods are still the major tools for isolating pure compounds, some developments like hydrophilic interaction chromatography (HILIC) have not been fully covered in previous reviews. Rep., 2008, 25, 517), a plethora of new reports on isolation of secondary compounds from higher plants, marine organisms and microorganisms has been published. In detail, it is planed to develop test methods that can be used to predict the performance of enzymes in particular process steps like deinking or refining and that can be used for quality control protocols.Since the last comprehensive review by Otto Sticher on natural product isolation in NPR (O. In trying to overcome the gap between the P&P industry and technology developers (enzyme suppliers), this study brings together experts in enzyme technology and the P & P industries to develop tools/protocols or basic procedures that will enable the P & P industry to fully and effectively use these enzyme based technologies in the future.
