目前的研究旨在鉴定 11 种桂苹果果实的植物化学物质和营养成分。种质FH29的总酚含量最高(492.45 mg 100 g(-1)鲜重)，高于参考水果蓝莓。连苯三酚被确定为所有品种中主要的酚类化合物。种质FH 29表现出最高的抗氧化能力(49.75μmol TEAC g(-1)鲜重)。种质中儿茶素含量较高； FH151、FH15、FH14、FH29、FH243、FH 239 和 FH 231。种质、FH14 和 FH232 表现出比参考水果苹果（品种顶级红）和桃子（品种卓越）更高水平的 β-胡萝卜素。种质FH240的总糖（葡萄糖和果糖）最高（50 mg g(-1)鲜重）。种质FH239和FH243中天冬酰胺(3122.18 mg L-1)和γ-氨基丁酸(1688.87 mg L-1)分别较高。总体而言，Kei-apple FH236 可以被视为必需氨基酸的良好来源。
Current study was initiated to identify the phytochemicals and the nutritional profile of eleven Kei-apple fruit accessions. Accession FH29 showed the highest level (492.45 mg 100 g(-1) fresh weight) of total phenolic content, higher than the referral fruit, blueberry. Pyrogallol was identified as the predominant phenolic compound in all accessions. Accession FH 29 showed the highest (49.75 mu mol TEAC g(-1) fresh weight) antioxidant capacity. Catechin content was higher in accessions; FH151, FH15, FH14, FH29, FH243, FH 239 and FH 231. Accessions, FH14 and FH232 exhibited higher levels of beta-carotene than the referral fruit apples (cv. Top red) and peaches (cv. Excellence). The total sugar (glucose and fructose) was highest (50 mg g(-1) fresh weight) in accession FH240. Asparagine (3122.18 mg L-1) and gamma-aminobutyric (1688.87 mg L-1) were higher in accessions FH239 and FH243 respectively. Overall, the accession Kei-apple FH236 can be regarded as a good source of essential amino acids.
