经特殊颜色反应、纸层析、紫外 -可见光谱、高效液相色谱、气相色谱和核磁共振波谱分析表明 :梅花‘南京红’花色色素的 3种主要花色苷分别是 :花青素 3 氧 (6″ 氧 α 吡喃型鼠李糖基 β 吡喃型葡萄糖 )苷 ,花青素 3 氧 (6″ 氧 没食子酰 β 吡喃型葡萄糖 )苷和花青素 3 氧 (6″ 氧 反式阿魏酰 β 吡喃型葡萄糖 )苷。花青苷在根本上决定着‘南京红’的粉红色花色 ,并可能强化‘南京红’的耐寒能力 ,也奠定了开发和利用该种花色色素的基础。
The results of special color reaction, paper chromatography, ultraviolet-visible spectroscopy, high performance liquid chromatography, gas chromatography and nuclear magnetic resonance spectroscopy showed that the three main anthocyanins of plum ’Nanjing Red’ were: anthocyanin 3 oxygen 6 “oxy-α-pyran-type rhamnosyl β-glucopyranoside, anthocyanin 3 oxygen (6” oxygal β-glucopyranoside) and anthocyanin 3 oxygen (6 " Glucosyl β-glucopyranoside). Anthocyanins fundamentally determine the pink color of ’Nanjing Red’ and may enhance the cold tolerance of ’Nanjing Red’ and lay the foundation for the development and utilization of this pigment .
