摘要:

簡述了超聲波強化逆流提取機的基本結(jié)構(gòu)和工作原理，并以水為溶媒,，菊花為原料,，進行了菊花有效成分的提取試驗,?？疾炝颂崛囟?、液料比和提取時間等因素對水溶出物和菊花黃酮提取得率的影響,，并通過L9(34) 正交試驗設(shè)計,，對提取工藝進行優(yōu)選。結(jié)果表明,，采用超聲波強化逆流提取機提取菊花有效成分最佳參數(shù)為：液料比20 mL/g,、提取溫度70℃、提取時間30 min,，所得提取物和總黃酮得率分別為

Abstract:

25.09%和12.42%,。The essential structure and principle of ultrasonic wave dynamic countercurrent extraction equipment were briefly introduced, and the experiment on extraction effective components of chrysanthemum has been studied by water as solvent and chrysanthemum as stuff. The key factors, which influenced on extraction yield of water-solubility matter and flavonoid, such as extracting temperature, ratio of liquid to solid and extracting time, were studied. The extraction technology was chosen by orthogonal test. The chrysanthemum's effective components were extracted by the ultrasonic wave dynamic countercurrent extraction equipment. The optimum results showed that the ratio of liquid to material was 20 mL/g, the temperature was 70℃, the time was 30 min, and the extraction rate of extracts and flavonoids were respectively 25.09% and 12.42%. 
