Pear is one of the main fruits with thousands of years of cultivation history in China. There are more than 2000 varieties of pear cultivars around the world, including more than 1200 varieties or cultivars in China (Legrand et al., 2016). Xinjiang Uygur Autonomous Region is an important pear production region in China with 30 of varieties or cultivars. Pyrus sinkiangensis is the most popular variety, which is mainly distributed in Xinjiang (Zhou et al., 2018). Chlorogenic acid (CGA), p-coumaric acid, and arbutin are the main polyphenols in pear fruit, and their levels show great differences among different varieties (Li et al., 2014). CGA is a potential chemo-preventive agent, which possesses many important bioactivities including antioxidant, diabetes attenuating, and anti-obesity (Wang et al., 2021). Therefore, the specific CGA content of a variety is considered the embodiment of the functional nutritional value of pears.
梨是中国具有数千年栽培历史的主要水果之一。全世界有超过 2000 个梨品种，其中中国有超过 1200 个品种或品系（Legrand 等人，2016 年）。新疆维吾尔自治区是中国重要的梨生产区，有 30 个品种或品系。新疆梨是最受欢迎的品种，主要分布在新疆（Zhou 等人，2018 年）。绿原酸（CGA）、对香豆酸和熊果苷是梨果实中的主要多酚类物质，其含量在不同品种之间存在很大差异（Li 等人，2014 年）。CGA 是一种有潜力的化学预防剂，具有许多重要的生物活性，包括抗氧化、糖尿病缓解和抗肥胖（Wang 等人，2021 年）。因此，一个品种的特定 CGA 含量被认为是梨功能营养价值的体现。
