Outcome Measures

Primary Outcomes (2)

  • Identification of metabolites in plasma and urine samples of 15 healthy volunteers after intake of grumixama juice by LCMS

    The blood and urine samples were collected in the times describe in "Arms and Interventions". The samples were acidified and the anthocyanins and ellagitannins metabolites were extracted by SPE column, these metabolites extracted were concentrated and analyzed by LC-ESI-MSn (for phenolic acids and anthocyanins) and LC-Q-TOF (for urolithins), the mass fragments were expressed in m/z.

    2 months

  • Identification of metabolites in plasma and urine samples of 15 healthy volunteers after intake of grumixama juice by GCMS.

    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.

    2 months

Secondary Outcomes (22)

  • Urinary creatinine values of 15 healthy volunteers for data normalization

    15 days

  • Cycle cell analysis in breast cancer cells treated with metabolites extracted from plasma and urine of 10 healthy volunteers after grumixama juice intake

    2 days

  • Multivariate data analysis of metabolites identified in plasma and urine of 15 healthy volunteers after intake of grumixama juice by GCMS

    2 months

  • Pathway analysis of metabolites identified by GCMS

Study Arms (1)

Grumixama Juice

OTHER

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.

Dietary Supplement: Intake of grumixama juice

Interventions

Intake of grumixama juiceDIETARY_SUPPLEMENT

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.
