[目的]对提取总黄酮后的花生壳残渣进行液化制取生物油,提高生物质的利用效率.[方法]在高压釜中乙醇作溶剂,高温对提取花生壳中黄酮类化合物后的残渣进行液化.[结果]通过对液化产物的物理性质、溶解度以及红外光谱的分析对比,表明液化产物的极性很大,流动性差、部分产物凝固,水溶性较差；固体剩余物比处理前变细,颜色各异但组成类同,液体产物基本相似,只有部分峰值位置和强度变化.[结论]直接浸提、超声波辐射法都是理想的总黄酮提取方法,但直接浸提法较好,是残渣处理的可行方法.%[Objective] To liquefy the peanut shell residues after the extraction of total flavonoids to produce bio-oil, and improve the utilization efficiency of biomass. [ Method ] With ethanol as solvent, the peanut shell residue was liquefied at high temperature in the autoclave. [ Result] According to its physical quality, dissolubility and infrared spectrum, the liquefied products had large polarity, slow mobility and low dissolubility, some of them were even solidified; the solid residues became fine, both the color and components differed largely from each other; while the liquid products were basically the same with only little changes in the position and intensity of some peak values. [Conclusion] Both direct extraction and ultrasonic-assisted extraction were ideal for extracting total flavonoids, but the former was better and practical for the treatment of residues.
