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 species using the μ-QuEChERS method combined with UHPLC-MS/MS analysis. The method showed good analytical performance, with linearity ( ≥ 0.991), LOQ ≤ 20 μg kg, 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) in 95% of these species, with values up to 56 times greater than resveratrol (0.3-7.5 mg kg). The highest piceatannol amounts were observed in the wild species (55.2 mg kg) and (44.7 mg kg). These findings highlight seeds as a valuable natural source of piceatannol, supporting their potential applications in functional foods, cosmetics, and pharmaceutical products.
百香果种子是果汁加工的副产品，富含具有促进健康特性的生物活性芪类化合物。本研究采用μ-快速、简便、廉价、有效、耐用和安全（QuEChERS）方法结合超高效液相色谱-串联质谱（UHPLC-MS/MS）分析，对4种商业品种和16种野生品种的种子中的白皮杉醇和白藜芦醇进行了研究。该方法具有良好的分析性能，线性关系（≥0.991）、定量限≤20μg/kg，相对标准偏差<11%。分别在70%和60%的分析品种中发现了白皮杉醇和白藜芦醇。在95%的这些品种中，白皮杉醇的含量显著更高（0.6-55.2mg/kg），其值比白藜芦醇（0.3-7.5mg/kg）高出56倍。在野生品种（55.2mg/kg）和（44.7mg/kg）中观察到最高的白皮杉醇含量。这些发现突出了百香果种子作为白皮杉醇宝贵天然来源的地位，支持了它们在功能性食品、化妆品和药品中的潜在应用。
