ABSTRACT

Análise da utilização da pimenta (Capsicum frutescens L.) e sua indicação medicinal: Revisão

“…Por conta desse largo curso de tempo, populações ameríndias descobriram modos de satisfazer, por meio desses vegetais, necessidades diversas, como as ligadas à alimentação e à cura de doenças. Incluíram-nos em cultos sagrados e nos arredores de suas habitações como plantas ornamentais (Bosland et al, 2000, Nuez et al, 1996, Bosland, 1999 (Custódio et al, 2010, Paula et al, 2010.…”

Chemical review and studies related to species from the genus Tynanthus (Bignoniaceae)

“…The substances β-sitosterol and apigenin were isolated from T. micranthus, as well as chemical groups such as flavonoids (dihidroflavonoids and leucoanthocyanidins), steroids and/or triterpenoids, heterosidic anthraquinones (Cansian et al, 2012) and eugenol in the essential oil (Custódio et al, 2010).…”

“…These preparations were also tested against some bacterial strains, and the results showed activity of the crude extract from the root against E. coli, whereas the crude extract from the stem was effective against S. aureus, P. aeruginosa and E. coli and the crude extract from the leaves was effective against S. aureus and P. aeruginosa, all of them with a minimal inhibitory concentration of 1000 μg/mL. Custódio et al, 2010 had previously evaluated the antimicrobial activity of the essential oil of T. micranthus, whose bioautography indicated eugenol as the substance responsible for its activity against Cladosporium herbarum . Cansian et al (2013) confirmed the influence of the chloroform fraction of the stem of T. micranthus on Lactuca sativa seeds hypocotyl germination and growth, indicating its allelopathic potential.…”
