Glucosinolate distribution in aerial parts of Degenia velebitica.

The glucosinolates present in the leaf, stem, and seed extracts of Degenia velebitica (Degen) Hayek were characterized and quantified according to the ISO 9167-1 method, which is based on the HPLC analysis of desulfoglucosinolates. The stems contained glucoalyssin (3a) as the major compound as well as glucoberteroin (1a) and glucoaubrietin (4a). The leaves contained three glucosinolates, the major one being 3a, followed by glucobrassicanapin (2a) and 1a.

Profile and quantification of glucosinolates in Pentadiplandra brazzeana Baillon.

Glucosinolates (GLs) present in root, seed, and leaf extracts of Pentadiplandra brazzeana Baillon were characterized and quantified according to the ISO 9167-1 method based on the HPLC analysis of desulfo-GLs. The analyses were complemented by GC-MS analyses of the isothiocyanates (ITCs) generated from GL degradation by myrosinase. Glucotropaeolin (1a), glucolimnanthin (2a), and glucoaubrietin (3a) were shown to be present in the root extract, whereas the seed mainly contained 3a.

A simple analytical method for dhurrin content evaluation in cyanogenic plants for their utilization in fodder and biofumigation.

Cyanogenic plants have some potential as biocidal green manure crops in limiting several soilborne pests and pathogens. Sorghum (Sorghum bicolor (L.) Moench) and Sudangrass (Sorghum bicolor subsp.
