目的 运用超分子印迹模板作用规律对金银花和山银花体外印迹等效性进行研究,旨在为金银花和山银花两花纷争提供新的解决方法。方法 以金银花药渣、山银花药渣、菊花药渣为主体分子,以金银花、山银花、双黄连(金银花)、双黄连(山银花)、银翘散(金银花)、银翘散(山银花)水提液为客体分子,3种主体分子和6种客体分子进行选择性吸附。采用HPLC法对吸附前后的客体分子水溶液指纹图谱进行测定。运用总量统计矩法计算总量一阶矩及其差值,并对差值进行t检验。结果 6种客体分子分别被金银花与山银花主体分子组、金银花与菊花主体分子组、山银花与菊花主体分子组吸附后,其总量一阶矩差值经t检验,P1=0.94>0.05、P2=0.02<0.05、P3=0.04<0.05。所有客体分子分别被金、山银花主体分子吸附后,其总量一阶矩差值无显著性差异。而被菊花主体分子吸附后,与被金银花和山银花主体分子吸附后相比均存在显著性差异。结论 金银花和山银花之间印迹模板具有相似性,而金银花和山银花与菊花之间印迹模板存在差异。说明金银花和山银花二者存在印迹等效性,这也与临床用药相符合。

Objective To explore and confirm the imprinting equivalence of Lonicerae Japonicae Flos (LJF) and Lonicerae Flos (LF) based on the autonomous function of the supramolecular imprinted template, and provide a new solution for double followers dispute. Methods Using LJF dregs, LF dregs, and Chrysanthemi Flos (CF) dregs as host molecules, and the water extract of LJF, LF, Shuanghuanglian (LJF), Shuanghuanglian (LF), Yinqiaosan (LJF), and Yinqiaosan (LF) as guest molecules, the selective absorb of three host molecules and six guest molecules was carried out. The change of fingerprint of water extract of guest molecules was determinated by HPLC. Then, the MRT and their difference value was calculated through the total quantum statistical moment method, and t-test was performed on it. Results When the six guest molecules was absorbed by LJF and LF dregs, LJF and CF dregs, LF and CF dregs, the MRT difference value was conducted by t-test. The results were P1=0.94 > 0.05, P2=0.02 < 0.05, and P3=0.04 < 0.05. We can see that all guest molecules was absorbed by LJF and LF dregs. There was no significant difference in the MRT difference value. But when six guest molecules was absorbed by CF dregs. There was significant difference between CF and LJF and CF dreg in the MRT difference value. Conclusion The statistical data indicated that similarity was existed in both "imprinted template" of LJF and LF. There was difference with CF. It is identified the exist of imprinting equivalence of LJF and LF, which is compatible with clinical medication.
