摘要: 为增强黑莓汁中花色苷的稳定,添加适量咖啡酸和阿魏酸到黑莓清汁中,采用可见吸收光谱和高效液相色谱-质谱研究其对黑莓花色苷的辅色作用。研究结果表明:黑莓汁中添加咖啡酸和阿魏酸显著增加了花色苷的最大吸收值(Aλmax),最大吸收波长(λmax)红移,说明咖啡酸和阿魏酸对黑莓汁中花色苷产生了辅色作用,辅色效应随时间的延长和咖啡酸、阿魏酸浓度的增加显著增强。HPLC-DAD-MS分析发现,咖啡酸辅色产生了两种新的花色苷衍生物(矢车菊素-3-O-葡萄糖苷-4-乙烯基儿茶酚和矢车菊-3-O-草酸酐酰葡萄糖苷-4-乙烯基儿茶酚),阿魏酸辅色产生了三种新的花色苷衍生物(矢车菊素-3-O-葡萄糖苷-4-乙烯基愈创木酚、矢车菊-3-O-草酸酐酰葡萄糖苷-4-乙烯基愈创木酚和矢车菊-3-O-阿拉伯糖苷-4-乙烯基愈创木酚),这些衍生物均为羟苯基-吡喃花色苷。

Abstract: To enhance the stability of anthocyanins in blackberry juice,the co-pigmentation effects of exogenous caffeic acid and ferulic acid on anthocyanins in blackberry juice were investigated using visible absorption spectra and HPLC-DAD-MS.The results showed that both caffeic acid and ferulic acid could significantly increase the absorption intensity (Aλmax) and its wavelength (λmax) of anthocyanins in blackberry juice.These phenomena suggested occurrence of co-pigmentation effects of caffeic acid and ferulic acid on anthocyanins in blackberry juice.The co-pigmentation intensity depended on duration and concentrations of caffeic acid and ferulic acid.Two new anthocyanin derivatives (cyanidin-3-glucoside-4-vinylcatechol and cyanidin-3-dioxalylglucoside-4-vinylcatechol) and three new anthocyanin derivatives (cyanidin-3-glucoside-4-vinylguaiacol,cyanidin-3-dioxalylglucoside-4-vinylguaiacol and cyanidin-3-glucoside-arabinoside-4-vinylguaiacol) were observed in blackberry juice with HPLC-DAD-MS analysis by adding caffeic acid and ferulic acid,respectively.
