Bioavailability of ellagitannins from cambuci (Campomanesia Phaea Berg) in healthy and obese subjects

Cambuci (Campomanesia phaea Berg) is a native fruit of the Atlantic Coastal Forest, belonging to the Myrtaceae family, rich in ellagitannins (ET), proanthocyanidins and other bioactive phenolic compounds (BPCs) related to beneficial effects to human health, such as systemic inflammation and attenuation o...

Role of phenolic compounds from brazilian native fruits on obesity-induced insulin resistance in skeletal muscle

Skeletal muscle is an important metabolic tissue in glucose uptake and thus in glycemic homeostasis. Evidence suggests that phenolic compounds may exert beneficial health effects against metabolic disorders associated to obesity including its state of peripheral insulin resistance. The objective of this ...

Influência do metil-jasmonato na formação de compostos voláteis do aroma em Bananas (Musa acuminata cv. Nanicão) e Laranjas (Citrus sinensis cv. Pera)

O principal hormônio associado aos processos do amadurecimento é o etileno, porém, na formação de compostos voláteis nos frutos, observa-se que as auxinas, o ácido abscísico e os jasmonatos também podem atuar como reguladores. Estudos indicam que em frutos climatéricos deve haver uma interaçã...
