摘　　要：为了解桑葚果酒和桑葚果实在酚类化合物的种类、含量及抗氧化活性之间的差异,该研究以桑葚果实、桑葚干酒和桑葚利口酒为试材,采用高效液相色谱串联电喷雾二级质谱(high performance liquid chromatography-electron spray ionization-mass spectrometry/mass spectrometry,HPLC-ESI-MS/MS)对酚类化合物进行定性定量分析。HPLC-ESI-MS/MS分析结果表明,在桑葚果实、桑葚干酒和桑葚利口酒中均检测到花青素-3-葡萄糖苷和花青素-3-芸香糖苷,而花葵素-3-芸香糖苷和4-丙酮酸-花青素-3-葡萄糖苷分别只在桑葚干酒和桑葚利口酒中被检测到。同时,桑葚干酒和桑葚利口酒中花青素-3-葡萄糖苷和花青素-3-芸香糖苷的含量均显著低于桑葚果实。此外,在桑葚果实中鉴定的8种非花色苷多酚中,仅有4种存在于桑葚干酒和桑葚利口酒中。相较于桑葚果实,桑葚干酒和利口酒中原儿茶素、二氢槲皮素和槲皮素的含量显著升高。桑葚果实DPPH自由基清除能力介于桑葚干酒和利口酒之间。综上,桑葚果酒和桑葚果实中酚类化合物的种类、含量及抗氧化活性之间差异显著。The aim of this study was to investigate the differences between mulberry wine and mulberry fruit in terms of the phenolic compounds and antioxidant activity.Qualitative and quantitative analysis of phenolic compounds in mulberry fruit,dry wine and liqueur were performed with HPLC-ESI-MS/MS.It was found that,anthocyanin-3-glucoside and anthocyanin-3-rutinoside were detected in mulberry fruit,dry wine and liqueur.Pelargonidin-3-rutinoside and 4-pyruvate-anthocyanidin-3-glucoside were detected only in mulberry dry wine and liqueur.The content of anthocyanin-3-glucoside and anthocyanin-3-rutinoside in both mulberry dry wine and mulberry liqueur was significantly lower than that in mulberry fruit.In addition,of the eight non-anthocyanidin phenolic compounds identified in mulberry fruit,only four were present in dry wine and liqueur.Compared to the mulberry fruit,mulberry dry wine and liqueur showed significantly higher contents of protocatechin,taxfolin and quercetin.The DPPH free radical scavenging activity of mulberry fruit was between mulberry dry wine and liqueur.In conclusion,there are significant differences between phenolic compounds and antioxidant activities in mulberry fruit and mulberry wine.
