Characterization of Red Dragon Fruit Peel Powder and Its Potential Role in Improving Vascular Function in Patients With Cardiometabolic Disorders

7. november 2026 opdateret af: University of Lahore

This study aims to characterize red dragon fruit (Selenicereus undatus) peel powder by evaluating its nutritional, physicochemical, and phytochemical properties. It will also explore its potential role in improving vascular function and cardiometabolic health among patients with cardiometabolic disorders.

Detaljeret beskrivelse

Cardiometabolic disorders including hypertension, dyslipidemia, and type 2 diabetes are strongly linked with vascular dysfunction, which increases the risk of cardiovascular morbidity and mortality. Conventional pharmacological therapies target metabolic abnormalities but often come with side effects, variable patient compliance, and limited improvement in vascular function. This has generated increasing interest in plant-derived nutraceuticals rich in bioactive compounds with antioxidant and endothelial-protective potential. Red Dragon Fruit (Selenicereus undatus (Haworth) D.R. Hunt) peel, usually considered an agro-waste, contains abundant betalains, flavonoids, dietary fiber, and essential minerals that may improve endothelial nitric oxide bioavailability, reduce oxidative stress, and modulate inflammatory pathways. This study aims to characterize the physicochemical and phytochemical profile of standardized dragon fruit peel powder and evaluate its potential role in improving vascular health in patients with cardiometabolic disorders. The intervention will involve daily supplementation with 4g, 6g and 8g of dragon fruit peel powder provided in a food-based vehicle along with DASH diet to three different groups over a period of 12 weeks. The study will enroll 90 adult participants aged 35-70 years diagnosed with at least one cardiometabolic disorder from CMH Hospital Lahore. Participants will be randomized into an intervention group receiving dragon fruit peel powder or a placebo group. Baseline and post-intervention assessments will include flow-mediated dilation (FMD), blood pressure, fasting glucose, HbA1c, lipid profile, inflammatory markers (hs-CRP, IL-6), and oxidative stress indicators (MDA, TAC). Statistical analysis will be performed using SPSS with significance set at p < 0.05. This study intends to establish Red Dragon Fruit peel as a safe, cost-effective, and sustainable dietary strategy for vascular health improvement and cardiometabolic risk reduction.
