Association of the soil bug Atarsocoris sp. (Hemiptera: Cydnidae) with the weed Senecio brasiliensis Less [PDF]

Neotropical Entomology, 2003
The burrowing bugs of the family Cydnidae, among them the brown burrowing bug Atarsocoris sp., are insect pests occurring in various crops, resulting in substantial losses in areas with high populations. Atarsocoris sp. is also frequently associated with weeds. The insect was found in the roots of the plant S.

Modulatory effect of Senecio brasiliensis (Spreng) Less. in a murine model of inflammation induced by carrageenan into the pleural cavity

Journal of Ethnopharmacology, 2015
Senecio brasiliensis (Spreng) Less (S. brasiliensis), known as "Flor-das-almas", "Margaridinha" or "Maria mole", is used in folk medicine as an anti-inflammatory and to treat gastric ulcers and stomach pain. While the Senecio genus has been widely studied for its pharmacological activities to support its use in traditional medicine, few studies focus ...

Recombinagenic activity of integerrimine, a pyrrolizidine alkaloid fromSenecio brasiliensis, in somatic cells ofDrosophila melanogaster

Environmental and Molecular Mutagenesis, 1997
Integerrimine (ITR), a pyrrolizidine alkaloid from Senecio brasiliensis, was tested for genotoxicity using the wing somatic mutation and recombination test (SMART) in Drosophila melanogaster. The compound was administered by chronic feeding (48 hours) of 3-day-old larvae.

Experimental poisoning by Senecio brasiliensis in calves: quantitative and semi-quantitative study on changes in the hepatic extracellular matrix and sinusoidal cells [PDF]

Pesquisa Veterinaria Brasileira, 2008
Extracellular matrix plays an important role in chronic hepatic lesions and has been studied in experimental intoxication models. However in cattle, studies on chronic disease have focused on the hepatocellular damage and extracellular matrix (ECM) changes are usually overlooked.

Modulation of gastrin and epidermal growth factor by pyrrolizidine alkaloids obtained fromSenecio brasiliensisin acute and chronic induced gastric ulcers

Canadian Journal of Physiology and Pharmacology, 2004
We investigated the antiulcerogenic activity of pyrrolizidine alkaloids (PAs) integerrimine, retrorsine, senecionine, usaramine and seneciplhylline, an alkaloidal extract obtained from Senecio brasiliensis. The PA extract demonstrated significantly activity in both, acute and chronic gastric ulcers on rats. The effects of PA extract were dose dependent.

Supercritical CO2 extraction of compounds from different aerial parts of Senecio brasiliensis: Mathematical modeling and effects of parameters on extract quality

The Journal of Supercritical Fluids, 2019
Abstract Senecio brasiliensis aerial parts extracts were obtained using supercritical carbon dioxide (SC-CO2) extraction. The objective was to evaluate the effects of temperature and pressure on the yield, extraction kinetics, and chemical composition. The extractions with SC-CO2 were performed at 15, 20 and 25 MPa, and 40, 50 and 60 °C.

Prenatal exposure to integerrimine N‐oxide enriched butanolic residue from Senecio brasiliensis affects behavior and striatal neurotransmitter levels of rats in adulthood

International Journal of Developmental Neuroscience, 2015
AbstractPyrrolizidine alkaloids (PAs) are toxins that are exclusively biosynthesized by plants and are commonly present in foods and herbs. PAs are usually associated with poisoning events in livestock and human beings. The aim of the present study was to evaluate the behavioral and neurochemical effects of prenatal exposure to PA integerrimine N‐oxide
