摘要
采用高效液相色谱法测定56份菠萝种质成熟果实中的有机酸组分及含量。结果表明,菠萝果实中有机酸主要由柠檬酸、苹果酸和奎宁酸组成,其中柠檬酸含量最高,变化范围在1.80～8.09mg/g FW,平均值4.82mg/gFW,占有机酸的64.73%,奎宁酸次之,苹果酸第三。奎宁酸在各种质间的变异相对稳定;柠檬酸和苹果酸变异较大,分别为33.86%和37.92%。根据柠檬酸所占的比例,可将菠萝种质划分为柠檬酸优势型。
The components and contents of organic acids in pineapple mature fruits from 56 germplasms were determined by high performance liquid chromatography（HPLC）. The results showed that the major components of organic acids in pineapple fruits were citric acid, malie acid and quinic acid. Citric acid was ranged from 1.80 mg/g FW to 8.09 mg/g FW, with a mean of 4.82 mg/g FW, and citric acid content was the highest value, which accounted for 64.73% of the value of organic acids, followed by quinic acid and malic acid. The variation range of quinic acid was relatively stable among different germplasms, while the value of citric acid and malic acid varied greatly, showing as 33.86% and 37.92%, respectively. All the germplasms could be classified into citric acid dominant based on their organic acid composition.
