摘要: 采用C18色谱柱,以甲醇:水:甲酸30min内,0.8ml/min梯度洗脱(从20:80:0.1到80:20:0.1)黑豆70%乙醇提取液。紫外光谱和电喷雾质谱的数据表明:大豆苷、乙酰基染料木苷、染料木苷、丙二酰基大豆苷、丙二酰基黄豆苷和丙二酰基染料木苷是黑豆种子中最主要的异黄酮,总含量为0.373%,为普通大豆种子异黄酮含量的2~6倍;黑豆是异黄酮的丰富来源。

Abstract: Mobile phases of 100% methanol/water/formic acid from 20:80:0.1 to 80:20:0.1 respectively in 30 min were used to elute black bean isoflavones at 0.8 ml/min,extracted by 70% ethanol from mature black bean seeds,in a C18 column with a high performance liquid chromatography(HPLC)system coupled with diode array detector(DAD)and mass spectrum(MS).Daidzin,acetyl genistin,genistin,malonyl daidzin,malonyl glycitin and malonyl genistin are identified as the main isoflavones with a total content 0.373%.Black bean is a good source of isoflavones for human health.
