Atividades antiúlcera e antioxidante Baccharis trimera (Less) DC (Asteraceae)

Abstract: RESUMO:A "carqueja", Baccharis trimera (Less) DC (Asteraceae), é uma espécie vegetal característica de regiões tropicais, muito utilizada na medicina popular como antiinflamatória, hipoglicemiante e em tratamento de problemas digestivos. A avaliação da atividade antiúlcera do extrato bruto liofilizado e do extrato liofilizado da "resina" (porção que durante a concentração dos extratos ficava depositada no fundo do recipiente com aspecto viscoso e pegajoso) foi realizada através de indução aguda por etanol acid… Show more

“…Thus, suggesting the absence of toxicity of different doses of HEBT administered orally (50-5000 mg kg −1 ) or intraperitoneally (1000 mg kg −1 ), and indicating the safety of HEBT, even at high doses. Our data corroborate those from Dias et al (2009) andNogueira et al (2011), who did not find alteration in mice after 2 weeks of a single 5000 mg kg −1 dose of B. trimera, p.o., and 4.20 or 42.00 mg kg −1 of B. trimera isolated compounds. The last authors observed toxic effects of B. trimera compounds only on kidneys cells in vitro.…”

“…In a stress-induced ulcer model and pylorus ligature model, Biondo et al (2011) reported the antiulcer and antisecretory activity of an aqueous extract of B. trimera (1000-2000 mg kg −1 ). B. trimera (100-400 mg kg −1 ) also had antiulcer activity in a model of stressinduced ulcers, a model of ethanol-induced acute gastric ulcers, and a model of hydrochloric acid-induced ulcers (Dias et al 2009;Mendonça et al 2013).…”

“…Biological assays aiming to attribute pharmacological actions for this species have been developed, evidencing anti-inflammatory and analgesic (Gené et al, 1996), antimutagenic (Nakasugi & Komai, 1998), antiulcer (Dias et al, 2009), smooth muscle vasodilation (Torres et al, 2000), hypoglycemic (Matos & Lorenzi, 2002;Barbosa-Filho et al, 2005), antiviral (Abad et al, 1999), gastroprotective (Gonzales et al, 2000), and antiarthritic effects (Coelho et al, 2004).…”

“…A Baccharis genistelloides é muito consumida no tratamento das complicações do trato digestório. O extrato aquoso da planta possui um complexo de saponinas, onde o componente predominante é o ácido equinocístico, produzindo assim a inibição da secreção e, como também a hiperacidez gástrica; além disso, os efeitos analgésicos e anti-inflamatórios também são encontrados nos extratos aquosos (Dias, Melo, Hernandes, Bacchi, 2009).…”
