Abstract: To promote the industrialization of resveratrol application,the dodecyl dimethyl betaine (BS-12)was selected as collector to recover resveratrol from Giant knotweed leaching solution by foam separation. This paper studied the effects of ellipsoid type foam separation tower,pH,dodecyl dimethyl betaine concentration and volumetric air flow rate on resveratrol separation efficiency. The results showed that the suitable operation conditions were leaching solution pH 3,the odecyl dimethyl betaine concentration 1.50g/L,and volumetric air flow rate 20mL/min. Under those operation conditions,the enrichment ratio and the recovery percentage of resveratrol were 8.43 and 81.73%,respectively. Then,the concentration of resveratrol in the foamate was 0.085 g/L. Furthermore,the biological activity of resveratrol could be kept during the process of foam separation. The present studies developed a green technology for effectively separating resveratrol from Giant knotweed leaching solution and then promoting the development and utilization of resveratrol.

Key words: Giant knotweed, resveratrol, separation, surfactants, foam, enrichment ratio, recovery percentage

摘要: 为了开发简单高效的从虎杖中提取白藜芦醇的方法,促进白藜芦醇的产业化应用,本文采用水提和泡沫分离相结合的方法,在泡沫分离过程中选用十二烷基二甲基甜菜碱作为捕获剂,泡沫分离虎杖浸提液中白藜芦醇。研究了椭球型泡沫分离塔、pH、十二烷基二甲基甜菜碱浓度、气体体积流量对泡沫分离白藜芦醇分离效率的影响,并对分离前后白藜芦醇的抗氧化性进行了研究。结果表明,采用椭球型泡沫分离塔,在pH为3、十二烷基二甲基甜菜碱浓度1.50g/L以及气体体积流量20mL/min的条件下,白藜芦醇富集比和回收率分别为8.43和81.73%,消泡液中白藜芦醇浓度为0.085g/L,而且泡沫分离过程中能有效保持白藜芦醇的生物活性。
