Covering: up to November 2012 Over the past 28 years there have been several thousand
publications describing the use of 2D NMR to identify and characterize natural products …

The major programs in North America designed to study plants as sources of potential drugs
in which ethnomedical information is used to some extent are reviewed. Most of this work is …

The relative merits of different pairs of two-dimensional NMR pulse sequences (COSY-90 vs
COSY-45, NOESY vs T-ROESY, HSQC vs HMQC, HMBC vs CIGAR, etc.) are compared and …

Laboratories around the world are challenged by the task of either verifying chemical
structures or elucidating the chemical structures of unknowns; each structure verified or …

Practical strategies for the structural elucidation of small organic molecules are described for
typical organic chemists. The analysis of an unknown is divided into three stages. First …

On a preliminary screening, substantial antimicrobial, antifungal and moderate insecticidal,
sporicidal and cytotoxic activities were observed for the hexane extract of the stem bark of …

Two potent stimulators of uterine contraction, the diterpenes kaurenoic and grandiflorenic
acids, were isolated from leaves of Aspilia mossambicensis. Their presence supports a …

There continues to be a disturbing number of natural products reported in the literature
whose structures are incorrect. At least in part, this reflects the fact that many natural product …

Long‐range heteronuclear chemical shift correlation has undergone a period of burgeoning
growth during the past 4 years. Initially, such correlations were made by simply reoptimizing …

Several modifications of the basic 13C 1H shift correlation sequence as optimized for
polarization transfer via long‐range 13C 1H coupling constants are described and …
