摘要:

以乙醇为溶剂, 利用超声辅助法提取红松松针中的多酚类化合物, 考察了乙醇的体积分数、  液料比(V(溶剂) ∶[KG-*3]m(松针))、 超声波功率、 超声温度及超声时间等条件对松针多酚提取质量比的影响, 得到了最适提取条件. 结果表明, 与传统有机溶剂回流提取法(醇提法)相比, 在最适提取条件下, 超声作用可以使提取时间缩短3 h, 提取的质量比达到52.97 mg/g, 提高了25.76%.

Abstract:

Polyphenol was extracted from the needles of Pinus prokoraiensis by means of ultrasound with ethanol as solvent. Effects of ethanol
 volume concentration, liquid to solid ratio (V(solvent) ∶[KG-*3]m(needle)), ultrasonic wave power, ultrasonic temperature as well as ultrasonic time were investigated and then the optimum extraction conditions were screened out. Under the optimum conditions, extraction time could be decreased by 3 h and extraction quantity of total polyphenol (52.97 mg/g) could be achieved under ultrasound. Compared with that of ethanol extraction, the extraction quantity was increased by a factor of 25.76% through ultrasonicassisted extraction.
