Abstract

ABSTRACT Research and development of natural antioxidants are gaining popularity with their wide application in food and medicine. Papaya (Carica papaya L.), a plant of medicinal and food value, is widely planted in tropical regions. This study was conducted to compare the tissues of different organs of papaya as well as the leaves and flowers of 9 cultivars of papaya. The three methods, namely, the 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, the 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assay and the ferric reducing antioxidant power (FRAP) assay, were used to determine the total antioxidant activities. Also, the total phenolic content and the total flavonoid content were investigated to evaluate the antioxidant capacity. Our research shows that leaves and roots of papaya manifested higher antioxidant properties among all tested organs, and leaves and flowers of Daqing cultivar exhibited the strongest antioxidant ability. Overall, our results indicate papaya has the potential to become a natural antioxidant resource.

几种木瓜品种不同部位抗氧化性分析

随着天然抗氧化剂在食品和医药领域的广泛应用，其研究与开发日益受到重视。番木瓜(Carica Papaya L.)是一种具有药用和食用价值的植物，广泛种植于热带地区。本研究对9个木瓜品种的不同器官组织及叶片和花朵进行了比较。采用2,2′-二苯基-1-吡啶肼(DPPH)自由基清除法、2,2′-氮基-双(3-乙基苯并噻唑-6-磺酸)(ABTS)自由基清除法和铁还原抗氧化能力(FRAP)法测定总抗氧化活性。并通过测定总酚含量和总黄酮含量来评价其抗氧化能力。研究表明，木瓜叶片和根部的抗氧化能力较强，其中大庆品种的叶片和花的抗氧化能力最强。总的来说，我们的研究结果表明木瓜有潜力成为一种天然的抗氧化资源。

期刊介绍： The International Journal of Fruit Science disseminates results of current research that are immediately applicable to the grower, extension agent, and educator in a useful, legitimate, and scientific format. The focus of the journal is on new technologies and innovative approaches to the management and marketing of all types of fruits. It provides practical and fundamental information necessary for the superior growth and quality of fruit crops. This journal examines fruit growing from a wide range of aspects, including: -genetics and breeding -pruning and training -entomology, plant pathology, and weed science -physiology and cultural practices -marketing and economics -fruit production, harvesting, and postharvest
