摘要： 采用一种改进的液泛提取装置提取桦树皮中桦木醇,该装置连接简单,操作方便,不影响提取率且可有效地提高样品的纯度。探讨了乙醇体积分数、提取时间对桦木醇提取率及纯度的影响,确定了桦木醇连续提取的工艺参数为:乙醇体积分数70%,提取时间50 min。利用此条件提取桦木醇,提取率达到(88.39±1.77)%,桦木醇纯度达到(80.34±0.25)%。

关键词: 桦木醇, 液泛提取, 高效液相色谱

Abstract: Betulin was extracted from white birch bark using a modified flooding extraction equipment. The equipment was easy-connected and conveniently-operated. It effectively improved the product purity without the change of yield. The effects of ethanol concentration and extraction time on the yield and purity of betulin was investigated. The optimal conditions were 70% of ethanol concentration, 50 min of extraction time. Under above conditions, the yield of betulin reached (88.39±1.77)% and the product purity was (80.34±0.25)%.

Key words: betulin, flooding extraction, HPLC
