Abstract

ABSTRACT This study aims to identify the individual phenolics and volatile compounds, as well as the organic acids of strawberry tree (Arbutus unedo L.) genotype fruits. The antioxidant activities were also assessed using three methods (DPPH, ABTS and βeta carotene bleaching assays) significant differences (p˂0.05) were observed among all the genotypes. Total phenols varied from 25.37 to 39.06 mg GAE/g dried weight (DW), total flavonoids ranged between 3.30 and 7.07 mg RE/g DW, and anthocyanins varied from 0.15 to 0.64 mg cya-3-glu/100 g DW. Moreover, the antioxidant activities were in the range of 3.33–21.08, 2.25–19.58, and 1.08–13 mg ascorbic acid equivalent/g DW for DPPH, ABTS and βeta carotene bleaching assays, respectively. Seventeen phenolics compounds were identified by HPLC in A. unedo fruits. Gallocatechol and catechin were the most abundant compounds. Among the volatile compounds identified, hexadecanoic acid was the most abundant in all the genotype fruits. The principal component analysis revealed that the first two components formed 66.47% of the total inertia.

草莓树(Arbutus Unedo L.)酚类、挥发性化合物、有机酸及其抗氧化活性摩洛哥生长的五种基因型水果

摘要本研究旨在鉴定草莓树(Arbutus unedo L.)基因型果实的酚类物质、挥发性化合物以及有机酸。采用DPPH法、ABTS法和β -胡萝卜素漂白法测定其抗氧化活性，各基因型间差异显著(p小于0.05)。总酚在25.37 ~ 39.06 mg GAE/g干重(DW)之间，总黄酮在3.30 ~ 7.07 mg RE/g DW之间，花青素在0.15 ~ 0.64 mg cya-3-glu/100 g DW之间。DPPH、ABTS和β -胡萝卜素漂白的抗氧化活性分别为3.33 ~ 21.08、2.25 ~ 19.58和1.08 ~ 13 mg抗坏血酸当量/g DW。HPLC法鉴定出17种酚类化合物。没食子儿茶素和儿茶素含量最高。在所鉴定的挥发性化合物中，十六烷酸在所有基因型果实中含量最多。主成分分析表明，前两个分量占总惯性的66.47%。

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
