| 目的 采用HPLC法同时测定不同采收期江枳壳中辛弗林和N-甲基酪胺的含量,考察不同采收期江枳壳中上述两种生物碱含量的变化。方法 采用高效液相色谱法。结果 辛弗林与N-甲基酪胺分别在1.09~5.45 μg(R2 = 0.9997),0.18~0.90 μg(R2 = 0.9999)范围内呈良好的线性关系;其平均回收率(n= 6)分别为102.30%和98.07%,RSD分别为2.12%和2.20% ;江枳壳样品中辛弗林和N-甲基酪胺的含量分别在0.07%~0.43%和0%~0.06%的范围内。结论 辛弗林含量随采收期的推迟而降低,N-甲基酪胺在当年7月份以后检测不到含量。该方法简便、准确、灵敏度高,可用于辛弗林和N-甲基酪胺的含量测定。 |

| Objective: To determine the contents of synephrine and N-methyltyramine in Jiangxi aurantii fructus at different harvest time by HPLC, and to investigate the changes of the two components. Methods: HPLC was applied in the experiment. Results: The method had good linear relationship within the range of 1.09~5.45 μg(R2 =0.9997)for synephrine and 0.18~0.90 μg(R2 = 0.9999)for N-methyltyramine. The average recoveries ( n = 6) were 102.30% with RSD of 2.12% for synephrine and 98.07% with RSD of 2.20% for N-methyltyramine respectively. The contents in Jiangxi aurantii fructus were 0.07%~0.43% for synephrine and 0~0.06% for N-methyltyramine respectively. Conclusion: The content of synephrine were low at late harvest time, N-methyltyramine wasn't detected since July. The method is convenient, accurate and highly sensitive, and can be applied to the determination of synephrine and N-methyltyramine in aurantii fructus. |
