| 摘 要： | 首次应用高效液相色谱-二极管阵列检测器-质谱联用技术(HPLC-DAD-MS)鉴定出紫皮豇豆主要含有三种花色苷,分别为飞燕草色素、矢车菊色素、天竺葵色素的葡萄糖苷,其中矢车菊葡萄糖苷相对百分含量达到93.4%;应用pH示差法测定出其单体花色苷的含量为57.15mg/100g鲜重;应用DPPH法测定结果显示,花色苷粗提液有较强的抗氧化能力。 |
| 关 键 词： | 紫皮豇豆 花色苷 抗氧化性 |

| Abstract: | Purple cowpeas(Vigna unguiculata L.)were extracted with of 0.1% HCl in methanol solution,purified on a C-18 solid cartridge,quantified by the pH differential method,and characterized by means of HPLC-DAD-IT/TOFMS analysis for the first time.Antioxidant activity of extracts was screened using DPPH radical scavenging methods.The content of anthocyanins in the purple cowpeas was 57.15mg/100g FW.Three kinds of anthocyanin riched in the extracts which exhibited strong antioxidant activity were identified,they we... |
