Descrição detalhada

The grumixama is a sweet and little cherry native of the South and Southeast regions of the Atlantic Forest of Brazil rich in phenolic compounds, mainly anthocyanins and ellagitannins. The objective of this study is Investigate the bioavailability of the main flavonoid, their colonic transformation and untargeted metabolites by an metabolomic approach following acute intake of a grumixama juice by humans.

Fifteen healthy subjects consumed grumixama juice at single dose, and urine and plasma samples were collected at different time points over 24 h period. The metabolites were analyzed by LC-ESI-MSn, LC-Q-TOF plasma and urine were also analyzed using untargeted metabolomic approach for amino acids and organic acids by GCMS.

Outro: Grumixama Juice

Juice of grumixama purple fruit (Eugenia brasiliensis Lam.), which is good source of anthocyanins and ellagitannins. It was made with filtered water and sanitized fruits, with a blender. It was administered in single dose of 0.97 mg of anthocyanins and of 4.71 mg of ellagitannins per mL of juice. Which volunteers ingested 10 mL of juice per each Kg body weight.

The metabolomic approach of plasma and urine samples following acute intake of grumixama juice was done by the collection of blood samples and urine, following the intake of grumixama juice.

In the morning of experimental day after 10 h fasting, the volunteers have been collect the first urine in the morning and it was collected the blood before the intake of grumixama juice, after they drink the juice (0 min), it was collected blood at the times: 15 min, 30 min, 60 min,120 min, 240 min and 24 h; and it was also collected urine at the period: 0 -1h, 1 - 2h, 2 - 4h, 4 - 6 h, 6 - 12 h, 12 - 14 h, the first urine in the morning in the second day (24 h). During the period in the first 4 h of experiment the volunteers only intake the juice.

Identification of metabolites in plasma and urine samples of 15 healthy volunteers after intake of grumixama juice by GCMS.
Prazo: 2 months
The samples were collected as describe in "Arms and Interventions", but for urine samples were used only the samples collected at times 0 (before the juice intake), 0-1h, 1-2h, 2-4h and at 24h after intake. The plasma samples had their proteins precipitated with cold methanol, the metabolites were extracted, concentrated and the amino acids and organic acids were derivatized to became volatile and the samples were analyzed by GCMS. For urine samples the procedures were similar. The mass fragment profile of derivatized compounds were compared to a GCMS library.
