Structural elucidation of saponins
1995Publisher Summary Saponins constitute an important class of secondary metabolites from plant and animal domains. They display a broad spectrum of biological activities that have raised the interest of phytochemists for the past 40 years. With molecular weights ranging from 600 to 2000 daltons, their structures are complex.

Structure Elucidation of Putisolvins
The present thesis investigates the cyclic lipopeptides putisolvins I and II through two independent yet complementary studies. The thesis details the structural elucidation of putisolvins I and II through UHPLC-MS using chiral column, multidimensional NMR spectroscopy, and computational analysis, which allowed for the assignment of 9 out of 12 ...openaire +1 more source
Challenging Structure Elucidator
2011This chapter will review examples of challenges solved using StrucEluc and will demonstrate all of the diverse approaches for computer assisted structure elucidation discussed in this volume. The examples will include (1) the elucidation of a family of complex alkaloid natural product structures (2) the elucidation of unexpected reaction products in a ...
