Abstract

The present research work was planned to explore the nutraceutical composition of sweet orange varieties during different developmental stages for fresh fruit consumption and industrial purposes. Five sweet orangeswere analysed for total phenolic content (TPC), total flavonoid content (TFC) along with the antioxidant capacity by four different assays viz. DPPH radical scavenging activity, hydroxyl ion (OH^–) activity, ferric reducing antioxidant power (FRAP) and total reducing power (TRP), some major flavanone like hesperidin and other like naringin. The outcomes of the research work revealed more pronounced antioxidant readings in Early Gold peel (90 days after fruit set, DAFS), while the phenolics were found maximum in the Ruby Nucellar peel; TPC at 90 DAFS (15.4 mg GAE g^–1 dry wt) and TFC at 150 DAFS (2.23 mg RE g^–1 dry wt). Whereas greater concentrations of hesperidin (7.25 mg g^–1 dry wt) and naringin (4.52 mg g^–1 dry wt) were detected in Itaborai at 90 DAFS.

甜橙品种在不同发育阶段生物活性化合物和抗氧化潜力变化的重点分析

摘要本研究工作旨在探索甜橙品种在不同发育阶段的营养保健成分，以供新鲜水果食用和工业用途。通过四种不同的检测方法，即 DPPH 自由基清除活性、羟基离子（OH-）活性、铁还原抗氧化力（FRAP）和总还原力（TRP）、一些主要的黄烷酮（如橙皮甙）和其他黄烷酮（如柚皮甙），分析了五个甜橙的总酚含量（TPC）、总黄酮含量（TFC）和抗氧化能力。研究结果显示，早金果皮（坐果后 90 天，DAFS）的抗氧化读数更明显，而红宝石果皮的酚类物质含量最高；90 DAFS 时的 TPC（15.4 毫克 GAE g-1 干重）和 150 DAFS 时的 TFC（2.23 毫克 RE g-1 干重）。而在 90 DAFS 时，在 Itaborai 果皮中检测到更高浓度的橙皮甙（7.25 毫克 g-1 干重）和柚皮甙（4.52 毫克 g-1 干重）。

期刊介绍： Russian Journal of Plant Physiology is a leading journal in phytophysiology. It embraces the full spectrum of plant physiology and brings together the related aspects of biophysics, biochemistry, cytology, anatomy, genetics, etc. The journal publishes experimental and theoretical articles, reviews, short communications, and descriptions of new methods. Some issues cover special problems of plant physiology, thus presenting collections of articles and providing information in rapidly growing fields. The editorial board is highly interested in publishing research from all countries and accepts manuscripts in English.
