摘要
目的:比较"抢青"采收(早于正常采收期的尚未成熟的果实)和正常采收早期采收的青翘中连翘酯苷A和连翘苷的含量差异。方法:采集了12个连翘主产地抢青采收和正常采收早期的青翘对应样品,采用高效液相色谱法测定其中连翘酯苷A和连翘苷的含量。结果:12组样品中,除个别组,抢青期的幼果中连翘酯苷A和连翘苷的含量高于正常采收早期,抢青采收期的连翘酯苷A和连翘苷的含量平均分别是正常采收早期的1.32倍和1.42倍。结论:抢青采收的连翘幼果中连翘酯苷A和连翘苷等成分含量高,高含量的功效意义值得关注。抢青采收对青翘产量影响巨大,应减少抢青采收对连翘野生资源的影响。
Objective： To compare the content of forsythoside A and phillyrin of Forsythiae Fructus collected in the earlier period harvest, called ＇ Qiang Qing＇ , andthe earlier than normal period harvest. Methods： 24 samples collected from 12 main distribution places of Forsythia suspensa with conresponding ＇ Qiang Qing＇ harvest and the earlier than normal period harvest. Forsythoside A and phillyrin content were determined by HPLC. Results： The contents of forsythoside A and phillyrin of the fruits in ＇Qiang Qing＇ period were higher than those with later period harvest in 12 groups of samples, except few groups. The average contents of these two chemicals were 1.32 times and 1.42 times higher, respectively. Conclusion： The significance of the high content of young fruit such as forsythoside A and phillyrin in ＂Qiang Qing＂ period should be concerned. ＇ Qiang Qing＇ harvest reduced the yield greatly and should be avoid and cut down.
