Determination of alkaloids in onion nectar by micellar electrokinetic chromatography
(2016)Nectar is the most important floral reward offered by plants to insects. Minor components such as alkaloid compounds in nectar affect bee foraging, with great influence in seed production. CE is an advantageous tool for ... -
Evaluation of the toxicological effects of Neltuma alpataco (Prosopis alpataco) pod alkaloid extract
(Elsevier, 2024-04)The pods of Neltuma spp. have shown potential as a source of protein and energy in livestock. However, prolonged consumption of some of these species can lead to neurological symptoms in ruminants. This study aimed to ... -
Genistin and quinolizidine alkaloid induction in L. angustifolius aerial parts in response to mechanical damage
(Taylor & Francis, 2013)Lupinus species are commonly used as annual forage and for grain production. They are considered alternative crops to soybean due to their adaptation to cool environments and dry soils. The present study is an analysis of ... -
Not all toxic butterflies are toxic: high intra- and interspecific variation in sequestration in subtropical swallowtails
(2017-12)Many herbivorous insects make use of plant secondary metabolites by consuming and storing these toxic compounds in their body tissue or integument, thereby obtaining chemical defense against their natural enemies. ... -
