酒花浸膏中的α-酸和β-酸的提取和提纯

EXTRACTION AND PURIFICATION OF SEPARATING α-ACIDS AND β-ACIDS FROM HOP EXTRACT

研究了利用酸和碱从酒花膏中提取α -酸和 β -酸的分离方法 ,并通过多次重结晶 ,纯化α-酸和 β -酸。

This paper gives the method of separating α-acids and β-acids from extracts by acids and alkali.The pure samples of α-acids and β-acids are obtained by multiple recrystallization.The melting point and ultraviolet spectrograph of the samples are identified with documents.α-acids and β-acidsare are separated completely,which is proved by the analysis of HPLC.
