不同产地百香果黄果主要功能成分含量及抗氧化活性比较

Main Functional Components and Antioxidant Activity of Yellow Passion Fruit (Passiflora edulis F. flavicarpa) from Different Origins

摘要:

为了解不同产地百香果黄果的功能品质，为百香果大健康产品的开发、产业化应用提供参考。以贵州5个栽培产地的百香果黄果为研究对象，对百香果黄果果汁的主要功能成分和抗氧化活性进行分析研究。结果表明，5个产地样品中Vc、总黄酮、总多酚、总多糖和总花青苷含量分别在74.85~192.79 mg VcE/100 g、16.06~51.85 mg RE/100 g、61.32~86.92 mg GAE/100 g、68.69~144.80 mg GE/g和0.12~1.23 mg CyGE/100 g之间；对DPPH、ABTS+和羟基自由基清除率分别在89.01%~97.03%、89.14%~95.59%、96.30%~99.31%之间。不同产地百香果受地区气候、平均气温、年降雨量、年日照情况的影响，果汁主要功能成分含量差异显著，且Vc含量、总多糖含量、抗氧化性能均较高，对DPPH自由基和羟基自由基的清除作用趋势相同。相关性分析得出，百香果果汁中Vc、花青苷、黄酮、多酚主要可加强对DPPH自由基、羟基自由基的清除，而多糖主要可加强对ABTS+自由基的清除。综合分析，相比黔南地区，黔东南地区产的百香果黄果主要功能成分含量高，抗氧化能力强，是用于开发功能性食品和保健食品的良好材料。

Abstract:

To understand the biochemical profile of yellow passion fruit (Passiflora edulis F. flavicarpa) from different origins, and provide reference for the development of industrial application of passion fruit health products. Yellow passion fruits from five cultivation areas in Guizhou, China, were selected for analysis of their main active components and antioxidant activities of their juice. Results showed that the contents of Vitamin C (Vc), total flavonoids, total polyphenols, total polysaccharides, and total anthocyanins ranged from 74.85 to 192.79 mg VcE/100 g, 16.06 to 51.85 mg RE/100 g, 61.32 to 86.92 mg GAE/100 g, 68.69 to144.80 mg GE/g, and 0.12 to 1.23 mg CyGE/100 g, respectively. The DPPH•, ABTS+•, and hydroxyl free radical scavenging rates ranged from 89.01% to 97.03%, 89.14% to 95.59%, and 96.30% to 99.31%, respectively. The contents of active components in passion fruit juice from different origins, vary significantly, due to effects of regional climate, average temperature, annual rainfall, and annual sunshine. The contents of Vc and total polysaccharides, and the antioxidant activities of passion fruit juice from all origins were high, and the scavenging effects on DPPH• and hydroxyl radicalswere similar. Correlation analysis indicates that Vc, anthocyanins, flavonoids, and polyphenols in the juice can strengthen scavenging capacity against DPPH• and hydroxyl radicals, while polysaccharides are able to enhance scavenging of ABTS+ radicals. In conclusion, compared to passion fruits produced in southern Guizhou, those grown in southeast Guizhou, have higher contents of active components and stronger antioxidant activities, and hence may be recommended as good material for developing functional foods and health products.
