F.Platonia insignis fruit, popularly known as bacuri, is traditionally used in folk medicine for its anti-inflammatory and antioxidant properties. Therefore, this study determined the chemical composition and biological activities of the bacuri’s shell and seeds extracts, considered residues from its consumption and industrial uses. Four biflavonoids (GB-2a, GB-1a, morelloflavone, and volkensiflavone) were identi...
Chemical composition and biological properties of Ipomoea procumbens
Batiga,Saadia; Valli,Marilia; Zeraik,Maria L.; Fraige,Karina; Leme,Gabriel M.; Pitangui,Nayla S.; Almeida,Ana Marisa F.; Michel,SylvieABSTRACT Natural products have been the most valuable source of chemical compounds in the discovery of novel medicines. Secondary metabolites from terrestrial and marine organisms have found considerable use in the treatment of numerous diseases and have been considered lead molecules both in their natural form and as templates for medicinal chemistry. Brazil has an exceptionally rich biodiversity, and a valuab...
