Diplodiosis is an important neuromycotoxicosis of ruminants in South Africa when grazing on harvested maize fields in winter. It is believed to be caused by mycotoxin(s) synthesised by Stenocarpella (Diplodia) maydis. Although several metabolites hav

The structure of monatin, a high-intensity sweetener isolated from Schlerochiton ilicifolius was elucidated by 1H and 13C NMR spectroscopy as 4-hydroxy-4-(indol-3-ylmethyl)glutamic acid. The 2R*,4R* relative configuration of the two chiral centres in
