The ethanolic extract from Erythrina mulungu Benth. flowers attenuates allergic airway inflammation and hyperresponsiveness in a murine model of asthma.

Ethnopharmacological Relevance: Erythrina mulungu Benth. ("mulungu", Fabaceae) is a Brazilian native species with ethnopharmacological use for respiratory diseases. However, the effects of E.

The glycosylated flavonoids vitexin, isovitexin, and quercetrin isolated from Serjania erecta Radlk (Sapindaceae) leaves protect PC12 cells against amyloid-β25-35 peptide-induced toxicity.

The Aβ peptide-mediated toxicity participates in the neuronal death that occurs in Alzheimer's disease. The present study aims to isolate the major compounds of Serjania erecta Radlk leaves and assess whether these compounds protect PC12 cells from Aβ25-35 peptide-induced toxicity. We isolated three flavonoid glycosides with high purity: quercetrin, vitexin, and isovitexin.
