| 摘 要： | 建立了同时测定生药厚朴中厚朴酚与和厚朴酚的荧光测定方法.液液萃取分离可基本消除样品提取液中共存杂质对测定的影响,通过选取适当的光谱校正点可扣除厚朴酚与和厚朴酚的光谱干扰和背景干扰.方法用于生药厚朴中厚朴酚与和厚朴酚的测定,5次测定相对标准偏差分别为厚朴酚3.97%及和厚朴酚2.67%,回收率为厚朴酚102.67%及和厚朴酚101.43%.

| Abstract: | A fluorescence analytical method is developed for the determination of magnolol and honokiol in Magnolia officinalis. The influence of coexistent impurities in the extraction solution of sample on the determination may be eliminated by use of liquid-liquid extraction method. The spectral and background interference for the analytical results can be deducted with an employable compensating process if the calibrated wavelength chosen is suitable. The method has been applied to the determination of magnolol and honokiol in Magnolia officinalis. The relative standard deviations of five detections are 3.97% for magnolol 2.67% for honokiol, and recoveries are 102.67% for magnolol 101.43% for honokiol, respectively. |
