Several fruit characteristics of five loquat (Eriobotrya japonica (Thunb.) Lindl.) cultivars/selections grown in Dörtyol, Hatay, Turkey were investigated in 2008. The cultivars/selections included 'Baduna 5', Güzelyurt 1, 'Hafif Cukurgöbek', 'Ottaviani,' and Type 1. The characteristics evaluated included fruit weight, width, length, seed number and weight, flesh/seed ratio, total soluble solids (TSS), pH, acidity, total phenolic (TP) content, and total antioxidant capacity (TAC), determined by the ferric reducing antioxidant power (FRAP) assay. The analyses were conducted by three replicates, with 30 fruits in each replicate. The results indicated that there were significant differences among the cultivars, for all the traits tested. For example, 'Hafif Cukurgöbek' and 'Ottaviani' had smaller fruits than others, although 'Hafif Cukurgöbek' had heavier seeds. The flesh/seed ratio was the highest in Type 1, while 'Hafif Cukurgöbek' had the highest pH and high soluble solids. 'Baduna 5' and 'Hafif Cukurgöbek' had the highest acidity. The TP ranged from 129 ('Baduna 5') to 578 ('Hafif Cukurgöbek') mg gallic acid equivalent (GAE)/kg fresh fruit (fw). 'Hafif Cukurgöbek' also had the highest FRAP mean (12.1 mmol Trolox Equivalent (TE)/kg fw). The results suggest that loquat cultivars have a variable range of TP content and a relatively high total antioxidant capacity, which is crucial for human health.
2008年，对在土耳其哈塔伊省多尔蒂奥尔种植的5个枇杷（Eriobotrya japonica (Thunb.) Lindl.）品种/选系的若干果实特性进行了研究。这些品种/选系包括“巴杜纳5号”、居泽吕特1号、“哈菲夫·库克古尔贝克”、“奥塔维亚尼”和1号类型。评估的特性包括果实重量、宽度、长度、种子数量和重量、果肉/种子比、总可溶性固形物（TSS）、pH值、酸度、总酚（TP）含量以及通过铁还原抗氧化能力（FRAP）测定法测定的总抗氧化能力（TAC）。分析进行了三次重复，每次重复30个果实。结果表明，在所测试的所有性状方面，各品种之间存在显著差异。例如，“哈菲夫·库克古尔贝克”和“奥塔维亚尼”的果实比其他品种小，不过“哈菲夫·库克古尔贝克”的种子较重。1号类型的果肉/种子比最高，而“哈菲夫·库克古尔贝克”的pH值最高且可溶性固形物含量高。“巴杜纳5号”和“哈菲夫·库克古尔贝克”的酸度最高。TP含量范围为129（“巴杜纳5号”）至578（“哈菲夫·库克古尔贝克”）毫克没食子酸当量（GAE）/千克新鲜果实（fw）。“哈菲夫·库克古尔贝克”的FRAP平均值也最高（12.1毫摩尔 Trolox 当量（TE）/千克fw）。结果表明，枇杷品种的TP含量范围各异且总抗氧化能力相对较高，这对人体健康至关重要。
