摘要: 目的:研究影响超声波辅助提取桔梗多糖的主要因素的影响规律,并确定最佳的超声波提取条件。方法:在考察超声波功率、超声波时间等单因素对桔梗多糖得率的影响基础上,选取液料比、超声波温度、超声波功率、乙醇浓度和超声波时间进行五因素五水平的二次正交旋转组合试验,以确定超声波辅助提取桔梗多糖最佳条件,并对最佳条件进行验证实验。结果:超声波辅助提取桔梗多糖的最佳条件液料比(V/W)范围为45.33~47.90,超声波温度为75℃,超声波功率范围为162~180W,提取液乙醇浓度范围为44.7%~49.8%,超声波时间为37~39min。此条件下多糖得率能达到35%以上。结论:超声波技术有利于桔梗多糖的提取,与对照实验方法相比,本研究方法短时高效。

Abstract: Objective: Effects of ultrasonic wave-assisted extraction on Radix platycdonis polysaccharide were studied. The optimal extract conditions were confirmed. Methods: Effects of each factor on polysaccharide were studied through single factor test, and then the optimal ultrasonic wave-assisted extraction conditions were confirmed through orthogonal test. Results: The optimal ultrasonic wave-assisted extraction conditions are as follows: ratio of solution to materiol (V/W) 45.33~47.90, temperature 75 ℃, power 162~180 W, time 37~39 min. On these conditions the extraction rate of polysaccharide is more than 35%. Conclusion: Ultrasonic wave-assisted extraction can benefit for polysaccharide extraction.
