Mansoins A (1) and B (2) isolated from the fruits of Mansoa hirsuta represent new glucosylated heterotrimeric flavonoids with a flavanone core linked to two 1,3-diarylpropane C6-C3-C6 units. Their structures and absolute configurations were established by analysis of their NMR and electronic
Continued investigation of the polyphenolic pool of the fruits of Mansoa hirsuta afforded four additional members of the new class of glucosylated oligomeric flavonoids comprising a flavanone core linked to 1,3-diarylpropane C6-C3-C6 units. The structures and absolute configurations of mansoins C-F
Mansoa hirsuta (Bignoniaceae) is a native plant from caatinga in Brazilian semiarid. This plant has been locally used as antimicrobial and hypoglycemiant agents, but their action mechanisms and toxicity remain largely unknown. Therefore, we evaluated the composition and antioxidant, cytoprotective
