摘要:

通过采用高效液相色谱(HPLC)法对不同产地富士苹果果实中多酚、可溶性糖及有机酸含量组分进行分析比较,结果表明:各个产地苹果果实中,总酚含量变化范围为101.99~177.62mg/100g,其中绿原酸含量均较高,其次为表儿茶素;总糖含量变化范围为83.71~119.60mg/g,其中果糖含量均较高,可达总糖含量的60.52%,与总糖呈正相关(r=0.92);总酸含量变化范围为3.785~4.808mg/g,苹果酸含量均较高,占总酸的比例高达93.20%,与总酸呈极显著正相关(r=0.98),琥珀酸含量次之。各产地富士苹果果实中总酚及糖、酸含量由高到低为:总酚:安塞>静宁>盐源>三门峡>洛川>铜川>天水>延安>烟台>凤翔>阿克苏>扶风;总糖:盐源>延安>三门峡>阿克苏>静宁>烟台>安塞>铜川>扶风>洛川>凤翔>天水;总酸:洛川>凤翔>铜川>烟台>静宁>阿克苏>三门峡>盐源>延安>安塞>天水>扶风。

Abstract:

The contents of polyphenols, soluble sugars and organic acids in Fuji apples from different growing regions
were analyzed and compared using high performance liquid chromatography (HPLC). Total polyphenol contents in Fuji
apples ranged from 101.99 to 177.62 mg/100 g, with chlorogenic acid being the most abundant component followed by
epicatechin. Total sugar contents varied between 83.71 mg/g and 119.60 mg/g, with fructose being the most abundant,
accounting for 60.52% and positively correlating with the total sugar amount (r = 0.92). Fuji apples from all growing regions
had total organic acid contents in the range of 3.785–4.808 mg/g, and malic acid was the most abundant acid, accounting for
93.20% and extremely significantly positively correlating with the total organic acid amount (r = 0.98), followed by succinic
acid. Different growing regions followed the decreasing order: Ansai > Jingning > Yanyuan > Sanmenxia > Luochuan >
Tongchuan > Tianshui > Yan’an > Yantai > Fengxiang > Akesu > Fufeng for total polyphenols, Yanyuan > Yan’an >
Sanmenxia > Akesu > Jingning > Yantai > Ansai > Tongchuan > Fufeng > Luochuan > Fengxiang > Tianshui for
total sugars, Luochuan > Fengxiang > Tongchuan > Yantai > Jingning > Akesu > Sanmenxia > Yanyuan > Yan’an >
Ansai > Tianshui > Fufeng for total organic acids.

Key words: Fuji apples, growing regions, polyphenols, soluble sugars, organic acids
