Abstract: High Resolution Image Download MS PowerPoint Slide Passion fruit seeds, a byproduct of juice processing, are rich in bioactive stilbenes with health-promoting properties. This study investigated piceatannol and resveratrol in seeds from four commercial and sixteen wild Passiflora species using the μ-QuEChERS method combined with UHPLC-MS/MS analysis. The method showed good analytical performance, with linearity ( R 2 ≥ 0.991), LOQ ≤ 20 μg kg –1, and RSD < 11%. Piceatannol and resveratrol were found in 70 and 60% of the analyzed species, respectively. Piceatannol was found in significantly higher amounts (0.6–55.2 mg kg –1 ) in 95% of these species, with values up to 56 times greater than resveratrol (0.3–7.5 mg kg –1 ). The highest piceatannol amounts were observed in the wild species P. longifilamentosa (55.2 mg kg –1 ) and P. edulis x P. caerulea (44.7 mg kg –1 ). These findings highlight Passiflora seeds as a valuable natural source of piceatannol, supporting their potential applications in functional foods, cosmetics, and pharmaceutical products.
