This study aimed to quantify the levels of resveratrol, coumarin, and other bioactives in pulps and by-products of twelve tropical fruits from Brazil obtained during pulp production process. Pineapple, acerola, monbin, cashew apple, guava, soursop, papaya, mango, passion fruit, surinam cherry, sapodilla, and tamarind pulps were evaluated as well as their by-products (peel, pulp's leftovers, and seed). Total phenolic, anthocyanins, yellow flavonoids, β-carotene and lycopene levels were also determined. Resveratrol was identified in guava and surinam cherry by-products and coumarin in passion fruit, guava and surinam cherry by-products and mango pulp. These fruit pulp and by-products could be considered a new natural source of both compounds. Overall, fruit by-products presented higher (P<0.05) bioactive content than their respective fruit pulps. This study provides novel information about tropical fruits and their by-products bioactive composition, which is essential for the understanding of their nutraceutical potential and future application in the food industry.
本研究旨在量化巴西 12 种热带水果在果肉生产过程中产生的果肉和副产物中的白藜芦醇、香豆素和其他生物活性物质的含量。评估了菠萝、 Acerola、Monbin、腰果苹果、番石榴、刺果番荔枝、木瓜、芒果、百香果、西印度樱桃、人心果和罗望子的果肉及其副产物（果皮、果肉剩余物和种子）。还测定了总酚、花青素、类黄酮、β-胡萝卜素和番茄红素的含量。在番石榴和西印度樱桃的副产物中鉴定到白藜芦醇，在百香果、番石榴和西印度樱桃的副产物以及芒果果肉中鉴定到香豆素。这些水果果肉和副产物可以被认为是这两种化合物的新的天然来源。总的来说，水果副产物的生物活性成分含量（P<0.05）高于各自的水果果肉。本研究提供了关于热带水果及其副产物生物活性成分的新信息，这对于理解它们的营养潜力以及未来在食品工业中的应用至关重要。
