This edition is a complementary extension of the fi rst edition rather than simply a revised and updated version. Thus, the majority of contributors are new, and the present aspects of bioactive natural product research were not necessarily covered in the fi rst edition. However, following in the same vein as the fi rst edition of this book, the reviewed and edited chapters of this second edition were written by international researchers representing a variety of scientifi c disciplines. Each contributor consequently approaches bioactive natural product research from a different perspective, highlighting the multidisciplinary and collaborative nature of this type of research.
