摘要:

采用超高效液相-三重四极杆串联质谱法对我国紫色马铃薯品种“黑金刚”中花青苷进行组分和含量分析。结果表明:紫色马铃薯中主要含有7种花青苷,分别是牵牛花素-3-芸香糖苷-5-葡萄糖苷、芍药素-3-芸香糖苷-5-葡萄糖苷、飞燕草素-3-p-香豆酰-芸香糖苷-5-葡萄糖苷、牵牛花素-3-咖啡酰-芸香糖苷-5-葡萄糖苷、牵牛花素-3-p-香豆酰-芸香糖苷-5-葡萄糖苷、牵牛花素-3-葡萄糖苷、芍药素-3-p-香豆酰-芸香糖苷-5-葡萄糖苷。其中牵牛花素-3-葡萄糖苷在马铃薯中首次发现。牵牛花素-3-p-香豆酰-芸香糖苷-5-葡萄糖苷是紫色马铃薯花青苷的主要组分,占总花青苷含量的64.6%(含量为5.04g/kg干质量),其次是芍药素-3-p-香豆酰-芸香糖苷-5-葡萄糖苷占总花青苷含量的20%(含量为1.56g/kg干质量)。

Abstract:

A UPLC-MS/MS method was used to determine the anthocyanin composition and content in “Heijingang”
purple potato. The results demonstrated that seven major compounds were detected in the purple potato cultivar, including
petunidin-3-rutinoside-5-glucoside, peonidin-3-rutinoside-5-glucoside, delphinidin-3-p-coumaroylrutinoside-5-glucoside,
petunidin-3-caffeoylrutinoside-5-glucoside, petunidin-3-p-coumaroylrutinoside-5-glucoside, petunidin-3-glucoside,
peonidin-3-p-coumaroylrutinoside-5-glucoside. To the authors’ knowledge, this is the first time that petunidin-3-glucoside
has been found in purple potato. Peonidin-3-p-coumaroylrutinoside-5-glucoside was one of the major compounds accounting
for 64.6% of the total anthocyanins (5.04 g/kg dry weight) followed by peonidin-3-p-coumaroylrutinoside-5-glucoside
accounting for 20% of the total anthocyanins (1.56 g/kg dry weight).
