【摘要】 本文采用毛细管区带电泳法（ＣＺＥ），以硼酸－磷酸混合体系作为背景电解质，对中药厚朴中两种具有生物活性的酚类成分（厚朴酚、和厚朴酚）进行分离。经过实验条件的优化，在０．０３ ｍｏｌ·Ｌ^－１硼酸－０．０１ ｍｏｌ·Ｌ^－１磷酸－２０％乙醇（ｐＨ １０．８０）缓冲液，检测波长２９４ｎｍ条件下，厚朴酚、和厚朴酚在１２分钟内可获得基线分离。实验表明这种方法简便快速，准确可靠，采用外标法可同时对厚朴中的厚朴酚、和厚朴酚进行定量测定。更多还原

【Abstract】 Two Pharmacologically active phenols （magnolol and honokiol） isolated from the Chinese herbal drug, Cortex Magnoliae Officinalis, were separated by capillary zone electrophoresis. After a series of optimization, baseline separation of magnolol and honokiol was obtained within 12 min by using the buffer system consisting of 0.03 mol·L^-1 borate and 0.01 mol·L^-1 phosphate, containing 20% methanol, at pH 10.80, and by DAD detection at 294 nm. With this simple and rapid method, the contents of two phenols in Cortex Magnoliae Officinalis were determined simultaneously by external standard method.更多还原
