Natural products – Discover their challenge and beauty
Natural products have always been among the most fascinating objects of the
practicing chemist. In fact, in many definitions of chemistry the isolation, purifi
cation and structural elucidation of natural products plays a central role. The his

In the past three decades there have been major advances in our understanding
of the chemistry and function of nutritional components. This has
been enhanced by rapid developments in analytical techniques and instrumentation.
