Glucosinolate profiling in Cleome gynandra L. aerial parts based on two extraction methods
Jonas Mano, Cedric Dicko, Jean Claude W. Ouédraogo, and Yvonne L. Bonzi-Coulibaly
Glucosinolates and their degradation products from Cleome gynandra L. are known for their beneficial effects in traditional medical use. As part of daily nutrient intake, the areal parts of this herb are cooked and consumed, whereas the residual water from boiling is discarded. However, it may contain valuable bioactive metabolites. Therefore,(...)
