Passion fruit (Passiflora edulis), including its leaves, is a rich source of bioactive compounds, as polyphenols. This study investigated the in vitro and vivo antioxidant potential aqueous extract P. edulis leaves identification phenolic compounds by HPLC-PDA ESI-MS/MS analysis. Male Wistar rats were divided two groups (n = 6 per group). Control group received water experimental leaf (Tea) (1.1 mg dry mL− 1), both ad libitum. Total phenols (DPPH, FRAP, ABTS ORAC assay) determined extract....
The bioactive compounds of freeze-dried jaboticaba peel (FJP), serum lipids and the antioxidant status rats fed high-fat diets containing different doses FJP were evaluated. Obesity was induced three groups obese animals received diet with 1%, 2% 4% added (J1, J2 J4, respectively). HPLC–DAD analyses polyphenols in showed four compounds: gallic acid, cyanidin 3-glucoside, ellagic quercetin. saturated fatty acids reduced J1 J4-fed animals. defenses plasma increased All prevented lipid...
The use of SPME fibers coated with porous polymer solid phases for quantitative purposes is limited due to effects such as interanalyte displacement and competitive adsorption. For air analysis, these problems can be averted by employing short exposure times samples flowing around the fiber. In conditions, a simple mathematical model allows quantification without need calibration curves. This work describes two portable dynamic sampling (PDAS) devices designed application this approach...
In this work, soft modeling based on chemometric analyses of coffee beverage sensory data and the chromatographic profiles volatile roasted compounds is proposed to predict scores acidity, bitterness, flavor, cleanliness, body, overall quality beverage. A partial least squares (PLS) regression method was used construct models. The ordered predictor selection (OPS) algorithm applied select for model each attribute in order take only significant peaks into account. prediction errors these...
In this study, we introduce a simple protocol to manufacture disposable, 3D-printed microfluidic systems for sample preparation of petroleum. This platform is produced with consumer-grade 3D-printer, using fused deposition modeling. Successful incorporation solid-phase extraction (SPE) microchip was ensured by facile 3D element integration proposed approach. μSPE device applied challenging matrices in oil and gas industry, such as crude oil-brine emulsions. Case studies investigated...
Passion fruit (Passiflora edulis) peel, a waste from food industrial processing, is still little explored. It contains fibers, including soluble which may be substrate for enteric bacteria and contribute to maintaining bowel health. The purpose of this work was investigate the action P. edulis peel in microbiota, production short-chain fatty acids (SCFAs), antioxidant potential colon Wistar rats. Seventy-seven-day-old male rats were divided into two groups: Peel Control (n = 4). Both groups...
The antioxidant and anti-inflammatory effects of the aqueous extract Passiflora edulis leaves, which is a source vitexin, isovitexin isoorientin, was investigated in 2,4,6-trinitrobenzenesulphonic acid induced colitis model. oral intake P. (1100 µg mL−1) improved significantly (P < 0.05) endogenous status decreased lipid peroxidation serum, liver, colon. consumption level pro-inflammatory colon tissue, especially by reducing IL-1β five-fold TNF-α two-fold compared to control group. leaves...
