hexane

1.METHODS The hydroxyl groups of magnolol were protected using ketol reaction and the products were purified by recrystallization from hexane.

方法将朴酚两羟基用缩,再用正己烷重结晶分离纯化。

2.The perservative in liquid beverage was extrcated with n-hexane.The hexane layer was subjected to cyclodextrine polymer resin colume.The colume was eluted with aqueous solution of ethanol.

用正己烷萃取体饮料中的防腐剂，使萃取经环糊精交联树脂分离后，用乙醇溶洗脱。
