This study aimed to analyze physicochemical characteristics and phenolic profile of twenty-three sweet cherry cultivars from Fundão region, Portugal. The average length and width ranged between 1.9 and 2.6 and 2.1-2.8 cm, respectively. Weight varied between 4.9 and 11.8 g, firmness ranged from 7.3 to 20.1 N, moisture and ash contents ranged from 75.1 to 88.6% and 0.4 to 2.9%, respectively. Sunburst and Sweetheart presented high values of CIEL∗, a∗ and b∗, and low values regarding total soluble solids and maturity index. A total of 46 phenolic compounds were identified by HPLC-DAD-ESI/MS and quantified by HPLC-DAD, namely 19 hydroxycinnamic acids, 2 hydroxybenzoic acids, 13 flavonols, 5 flavan-3-ols, 2 flavanones, 1 flavanonol and 4 anthocyanins. Sunburst and Brook's were the richest in non-colored phenolics, while Garnet and Tavora were the richest ones in anthocyanins. Therefore, our results revealed that sweet cherries represent a supply of high-value bioactive compounds, being greatly influenced by the cultivar.
本研究旨在分析来自葡萄牙丰当地区的二十三个甜樱桃品种的理化特性和酚类物质特征。果实的平均长度和宽度分别在 1.9-2.6cm 和 2.1-2.8cm 之间，重量在 4.9-11.8g 之间，硬度在 7.3-20.1N 之间，水分和灰分含量在 75.1%-88.6%和 0.4%-2.9%之间。Sunburst 和 Sweetheart 呈现出较高的 CIEL∗、a∗ 和 b∗ 值，而总可溶性固形物和成熟指数较低。通过 HPLC-DAD-ESI/MS 共鉴定出 46 种酚类化合物，并通过 HPLC-DAD 进行定量分析，包括 19 种羟基肉桂酸、2 种羟基苯甲酸、13 种类黄酮、5 种黄烷醇、2 种黄烷酮、1 种黄烷醇和 4 种花青素。Sunburst 和 Brook's 品种中非花色酚含量最高，而 Garnet 和 Tavora 品种中花青素含量最高。因此，我们的研究结果表明，甜樱桃是高价值生物活性化合物的重要来源，其品种对这些化合物的含量有很大的影响。
