摘 要:
以杭白菊为原料，探讨了超声波萃取对杭白菊中酚类化合物提取的影响。研究发现：随着超声波频率提高及萃取时间的延长，杭白菊提取液中总固形物、总多酚化合物、类黄酮及单宁含量均呈增加趋势，在100kHz及80℃下萃取较100℃热水萃取效果更好。[著者文摘]

Abstract:
This experiment uses domestic Florist Chrysanthemum as the raw materials and examines the effects of ultrasonic extraction on the total pelyphenolic compounds of the extracted liquid. The experimental results were as follows ： Along with the increase in the ultrasonic frequency and time, there was an increasing trend in the total solids contents, total pelyphenolie compounds, flavonoids contents and tannin contents of the Florist Chrysanthemum extracted liquid. The results of the extraction at 100kHz ＋ 80℃ were better than that at 100℃ boiling water.[著者文摘]
