A GC method for the determination of bakuchiol of described. GC conditions for analysing are as follows: stationary phase: SE-30: injector temperature: 250 degrees C: column temperature: 200 degrees C and detector: FID. The linear range of this method is 0.24-2.4 micrograms and the average recovery is 98.82%, with a relative standard deviation of 1.58%. This method has been successfully used to determine the content of bakuchiol in the samples on the market in 11 different areas, the contents being 1%-7%.
本文描述了一种用于测定补骨脂酚的气相色谱法。分析的气相色谱条件如下：固定相：SE - 30；进样口温度：250℃；柱温：200℃；检测器：氢火焰离子化检测器（FID）。该方法的线性范围为0.24 - 2.4微克，平均回收率为98.82%，相对标准偏差为1.58%。该方法已成功用于测定11个不同地区市售样品中补骨脂酚的含量，含量为1% - 7%。
