Abstract

The agricultural and food industries produce many byproducts that are rich in natural antioxidants with potential health benefits. This study aims to extract bioactive compounds from the yellow passion fruit rind (YPFR), with therapeutic properties like antibacterial, anticancer, and antioxidant activity. In this study, phytochemical extraction was performed using supercritical fluid extraction with CO₂ and 10% ethanol as co-solvent (SC-ET), and ultrasound-assisted extraction (UAE) with 65% ethanol. Both methods were compared for extraction yield, phytocomponents, antioxidant, and antibacterial activity. Phytochemical analysis showed significant phenolic, flavonoid, and carotenoid contents in extracts, contributing to its increased antioxidant activities. SC-ET exhibited higher flavonoid and carotenoid concentrations, however, UAE yielded higher phenolics. These support higher antioxidant capacity in SC-ET compared to the UAE during the Global Antioxidant Score (GAS). GC-MS identified 75 compounds in UAE extracts and 47 in SC-ET extracts, whilst HPLC profiling indicated higher phenolic and flavonoid contents in SC-ET extracts, demonstrating SFE’s selectivity and UAE’s broader compound extraction range. Both extracts showed significant antibacterial activity, with SC-ET being more potent. These findings revealed the potential of using passion fruit peel to extract bioactive compounds for the food, pharmaceutical, and cosmetic industries, promoting sustainable waste management and resource recovery.

超声波与超临界流体萃取法提取百香果废弃物的比较研究

农业和食品工业生产的许多副产品富含天然抗氧化剂，对健康有潜在的好处。本研究旨在从西番莲黄果皮（YPFR）中提取具有抗菌、抗癌、抗氧化等治疗作用的活性化合物。在本研究中，采用超临界流体萃取，以CO2和10%乙醇为助溶剂（SC-ET），超声辅助萃取（UAE）， 65%乙醇。比较了两种方法的提取率、植物成分、抗氧化和抗菌活性。植物化学分析表明，提取物中酚类、类黄酮和类胡萝卜素含量显著增加，有助于提高抗氧化活性。SC-ET表现出更高的类黄酮和类胡萝卜素浓度，然而，阿联酋产生更高的酚类物质。与全球抗氧化评分（GAS）相比，SC-ET的抗氧化能力更高。GC-MS鉴定了UAE提取物中的75种化合物和SC-ET提取物中的47种化合物，HPLC分析表明SC-ET提取物中酚类和类黄酮含量较高，证明了SFE的选择性和UAE更广泛的化合物提取范围。两种提取物均表现出显著的抗菌活性，其中SC-ET的抗菌活性更强。这些发现揭示了利用百香果皮提取食品、制药和化妆品行业的生物活性化合物，促进可持续废物管理和资源回收的潜力。图形抽象
