【摘要】 研究了功率超声的频率、时间对厚朴药材中的厚朴酚提取量的影响。实验结果表明 ,超声频率为 2 0kHz的提取量较高 ,提取时间以 10min以上为宜。与冷浸法和超临界流体萃取法相比 ,超声法具有浸取时间短、提取率高的优点更多还原

【Abstract】 In this paper,the leaching of magnolol in Magnolia officinalis Rehd et Wils by power ultrasound was studied with respect to the effects of different ultrasound frequency and leaching time.Experimental results show that more magnolol can be acquired when the ultrasound frequency is 20 kHz and the leaching time is over 10 minutes.The leaching by power ultrasound has shorter leaching time, higher yield than cold leaching method and supercritical fluid extraction (SFE) method.更多还原
