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...
Nos últimos tempos, grande destaque tem sido dado no estudo de sistemas bio(muco)adesivos de liberação de fármacos, os quais podem promover um direcionamento e uma retenção mais específica do fármaco incorporado no sistema de liberação, empregando as mais variadas membranas de absorção do organismo. Esta plataforma tecnológica combinada com a nanotecnologia oferece possibilidades como a proteção e o controle da...
For the construction of the phase diagrams, the method of the aqueous titration was used. There were prepared 5 ternary diagrams, varying the surfactant and the oil phase. The liquid-crystalline phases were identified by polarized light microscopy. The formulations prepared with silicon glycol copolymer, polyether functional siloxane (PFS) and water (S1) and with diisopropyl adipate, PFS and water (S4) presente...
