摘要
采用高效液相色谱与离子阱串联飞行时间检测器-质谱联用技术,分离鉴定欧李中的花色苷类化合物。结果表明:从欧李红色素中分离得到6种组分,分别为:矢车菊-3-葡萄糖苷、天竺葵-3-葡萄糖苷、矢车菊-3-鼠李糖葡萄糖苷、天竺葵-3-鼠李糖葡萄糖苷、矢车菊-3-乙酰基葡萄糖苷、天竺葵-3-乙酰基葡萄糖苷。其中,矢车菊-3-葡萄糖苷为主要花色苷,占欧李总花色苷含量的62.6%。因此,采用高效液相色谱-质谱联用技术可有效地分离分析欧李中花色苷类物质。
The objective of this study was to isolate and identify the anthocyanins in the fruits of Prunus humilis Bunge by high performance liquid chromatography-electrospray ionization tandem mass spectrometry.Six compounds were isolated and identified to be cyaniding-3-glucoside,geranium-3-glucoside,cyanidin-3-rhamnosyl glucoside,geranium-3-rhamnose glucoside,cyanidin-3-acetyl glucoside and geranium-3-acetyl glucoside.Among them,cyaniding-3-glucoside was the major anthocyanin,accounting for 62.6% of the total anthocyanins.In conclusion,high performance liquid chromatography-electrospray ionization tandem mass spectrometry can efficiently analyze the composition of anthocyanins in the fruits of Prunus humilis Bunge.
