摘要: 本研究探讨了虎杖中白藜芦醇的提取工艺和稳定性。在虎杖中,白藜芦醇对光、干热、湿热和氧化剂均敏感;通过实验得出回流、超声、固定床连续提取的提取率分别0.201%、0.423%、0.513%;同时利用正交设计得出固定床连续提取的最佳工艺为溶剂为30%乙醇,固定床连续提取速度为8ml/min·kg,浸泡时间为12h,溶剂用量为8倍量。

Abstract: The extraction processing and stability of the resveratrol from Polygonum cuspidatum were studied in this research. The resveratrol is unstable against light, heat, wet-heating and oxidant. On the base of experimental analysis, the extraction rate of reflux extraction, continuous fixed bed extraction and ultrasonic extraction were 0.201%, 0.423%, 0.513%. And continuous fixed bed extraction is optimized by orthogonal test method. The optimum conditions were obtained as follows: the concentration of the ethanol 30%, extracting speed 8 ml/min·kg, immersion time 12 h and the solvent 9 times of the material.
