摘要: 采用乙醇溶液浸提、水溶液浸提、乙醇抽提三种方法提取苦荞麦麸皮中的黄酮类化合物。结果表明:乙醇溶液浸提的最佳提取工艺条件是:A3B2C2D2,即用10倍75%乙醇在70~75℃下浸提4h;水浸提的最佳工艺条件是:最佳提取组合为A3B3C3,即用20倍水量在70~75℃下浸提6h。乙醇溶液抽提的最佳工艺条件是:95%的乙醇回流抽提8h。

Abstract: s: Three approaches, ethanol immersion extraction water immersion extraction and ethanol Soxhlep Extractor extraction, were used to extract flavonoid compound from the tartay buckwheat bran. The results showed that the optimum conditions of the ethanol immersion extraction were 70~75℃ and 10:1 of 75% ethanol extraction 4h and the water immersion extraction 70~75℃and 20:1 of water extraction 6h, while the optimum conditions of the ethanol soxhlet extraction were 95% ethanol back-flow extraction 8h.
