Researchers from both industry and academia present in detail techniques for the extraction and isolation of natural products of all classes. These experienced experimentalists describe a wide array of methodologies, including basic chromatography, ion-exchange methods, HPLC, countercurrent and planar chromatography, SFE, and crystallization. They also address the specific problems involved in working with plants, marine organisms, water-soluble compounds, scale-up, dereplication and partial identification, and follow-up of a natural product lead. For the less-experienced they offer hands-on advice-using real examples-about how to approach an extraction in general, when and why to apply a particular technique, how to carry out the methods described, and how to modify conditions according to the compound being isolated. weiterlesen
