山东平邑金银花不同花期绿原酸和木犀草苷动态变化研究

目的：研究山东平邑不同采收期金银花中绿原酸和木犀草苷动态变化，为山东平邑金银花药材采收期的确定提供理论依据。方法：以金银花药材中绿原酸、木犀草苷含量、高效液相指纹图谱相及干花得率为指标考察金银花药材三青期、二白期、大白期、银花期、金花期5个不同采收期药材的质量。结果：不同采收期金银花中绿原酸、木犀草苷含量有明显变化，干花质量与产量也有明显变化。结论：金银花质量与采收期密切相关，在二白期、大白期采收质量最好。

The Optimum Harvest Time of Lonicera japonica

Objective：to study the different harvest time of chlorogenic acid in honeysuckle herbs and mignonette nucleoside dynam- ic change, determine provide theoretical basis for honeysuckle herbs harvest time. Methods： of chlorogenic acid in honeysuckle herbs, mignonette glucoside content, highly effective liquid phase fingerprint and drying process in the indicators of dried flowers yield stage three blue honeysuckle herbs, 2 white, stage light, honeysuckle, gold flowering five different harvest time the quality of medicinal materials. Results：2 white period honeysuckle dried flowers at a rate of 22 %, chlorogenic acid content is 3.2 %, mignon- ette glycosides content is 0.11 ~, highly effective liquid phase fingerprint similarity is greater than 0.95. Conclusion： honeysuckle herbs 2 white period is the best harvest time, and provide theoretical basis for harvesting of honeysuckle herbs.
