商洛不同产地青翘和老翘中连翘苷及连翘酯苷A含量研究

目的比较商洛不同产地连翘果实(青翘和老翘)中有效成分连翘苷及连翘酯苷A的含量。方法高效液相色谱法(HPLC)。结果青翘中连翘苷及连翘酯苷A含量普遍高于老翘,其中,山阳石头梁、山阳赵川所采样品连翘苷含量分别高达0.862%、0.782%,洛南灵口老翘中连翘苷含量最低为0.106%。丹凤峦庄、洛南灵口所采样品连翘酯苷A含量分别高达13.24%、12.18%,山阳石头梁老翘中连翘酯苷A含量最低为0.371%。结论商洛不同产地的青翘和老翘中连翘苷、连翘酯苷A含量差异十分明显,在开展连翘资源开发和规范化种植时应加强种质的选择,合理选择采摘时间。

Research of Phillyrin and Forsythoside A in Green and Grown Fructus Forsythiae from different areas in Shangluo

Objective To compare the active ingredient content of Phillyrin and Forsythoside-A in Forsythia（ Green and Grown Forsythiae） fruits from different producing areas in Shangluo. Methods High Performance Liquid Chromatography（ HPLC）. Results The active ingredient content of Phillyrin and Forsythside A in Green Forsythiae is higher than that of Grown Forsythiae. Among them,Phillyrin contents in Grown Fosythiae of the sample of Shitouliang and Zhaochuan in Shanyang County were as high as 0. 862% and 0. 782%. But in Lingkou of Luonan County,it＇s only 0. 106%. In the samples of Luanzhuang of Danfeng County and Lingkou of Luonan County,the contents of Forsythside-A were up to 13. 24% and 12. 18% respectively. But the content of Forsythside-A of Grown Forsythiae is only 0.371% in Shitouliang of Shanyang County. Conclusion In different origins of Shangluo District,the Phillyrin and Forsythoside-A content in Green and Grown Forsythiae have great differences. At the time of the Forsythia planting,we should strengthen the variety selection and reasonable choice of picking time.
