Purification of polyphenol in Mulgedium tataricum L.with macroporousresin
摘要
Abstract
According to adsorption and desorption performance towards polyphenol,an optimal macroporous resin was selected from D-101,NKA-9 and AB-8 resins to purify crude polyphenol extracted from Mulgedium tataricum L.The results showed that D-101 was the optimal resin and consequently,was chosen.The optimal adsorption and desorption conditions of Mulgedium tataricum L.polyphenol were determined as follows：The adsorption equilibrium time was 150min and desorption 120min.Polyphenol concentration of sample was 0.2mg·mL-1,pH4,the optimal desorbent concentration,flow rate and elution volume for the desorption of Mulgedium tataricum L.polyphenol were 60% ethanol,0.5mL·min-1 and 3BV.Ultraviolet absorption showed that Mulgedium tataricum L.polyphenol purity was improved after column adsorption,which indicated D-101 could be furtherly used to purify Mulgedium tataricum L.polyphenol.关键词
