Chemical Diversity of Plant Cyanogenic Glycosides: An Overview of Reported Natural Products

Cyanogenic Glycosides in Plant Foods

Cyanogenic and non-cyanogenic glycosides from Manihot esculenta.

In addition to lotaustralin and linamarin, a novel cyanogenic glycoside, 2-((6-O-(beta-D-apiofuranosyl)-beta-D-glucopyranosyl)oxy)-2-met hylbutanenitrile , two novel non-cyanogenic glycosides, (2S)-((6-O-(beta-D-apiofuranosyl)-beta-D- glucopyranosyl)oxy)butane and 2-((6-O-(beta-D-apiofuranosyl)-beta-D-glucopyranosyl)oxy)propane, and a simple non-cyanogenic glycoside, ethyl beta-D-glucopyranosid...

Statistical reanalysis of natural products reveals increasing chemical diversity.

In their retrospective analysis of natural product (NP) discovery since the 1940s, Pye et al. (1) observe a gradual decline in the proportion of NPs discovered each year with low similarity to previously known compounds [defined by maximum Tanimoto coefficient (Tc) < 0.4]. Additionally, the authors report that the median maximum Tc for all NPs discovered in a given year has plateaued since the ...

Straightforward rapid spectrophotometric quantification of total cyanogenic glycosides in fresh and processed cassava products.

In this study, we extend pioneering studies and demonstrate straightforward applicability of the corrin-based chemosensor, aquacyanocobyrinic acid (ACCA), for the instantaneous detection and rapid quantification of endogenous cyanide in fresh and processed cassava roots. Hydrolytically liberated endogenous cyanide from cyanogenic glycosides (CNp) reacts with ACCA to form dicyanocobyrinic acid (...
