Separation Techniques
Efficient separation techniques are key for competitive natural product chemistry, nowadays. Available technologies range from high-throughput separation for quantitative analysis of target molecules at femto- or picogram levels all the way up to the gram-scale preparative isolation of bioactive molecules from nature’s complex compound mixtures such as, e.g. food and botanical extracts, plasma, saliva, and urine.
