Changes in Lupinus albus and Lupinus angustifolius alkaloid profiles in response to mechanical damage.

The aim of this work was to evaluate chemical responses to biomass removal mimicking large herbivore action in Lupinus albus and Lupinus angustifolius aerial parts. GC and GC-MS were used to determine total alkaloid content (TAC) and alkaloid relative abundances in bitter and sweet varieties of each species. Bitter genotypes Vila vehla (Vv; 3.

Soil quality effects on Chenopodium album flavonoid content and antioxidant potential.

Antioxidant capacity, total phenolic content and flavonoid glycosides profile were compared in C.album samples grown in intensively cultivated (IC) and nondisturbed (ND) soils to evaluate differences in their nutraceutical potential. Petroleum ether, methanol, and aqueous extracts were sequentially obtained from C.
