不同采收期金银花的产量和质量研究

Study on yield and quality of Lonicerea Japonicae Flos in diferent harvest seasons

目的研究不同采收期对金银花产量和质量的影响,为金银花的合理采收、批号划分和综合开发利用提供参考。方法在金银花不同的发育时期、采收时间,采集不同部位的样品,测定其生长指标、产量和绿原酸、木犀草苷量。结果金银花不同采收期和忍冬不同采收部位的各项生长指标、产量和绿原酸、木犀草苷量差异显著。结论金银花宜在"二白"至"大白"期采摘;第一茬花产量高、质量好,其次为第二茬花;忍冬枝叶绿原酸和木犀草苷的量较高,可以进行有效成分提取和综合利用。

Objective To investigate the influence of different parts and different harvest seasons on the yield and quality of Lonicerea Japonicae Flos （LJF）, and to provide the reference for the reasonable harvest, lot division, and comprehensive utilization. Methods After collecting samples from different parts at different periods, the growth index, yield, and chlorogenic acid and galuteolin contents of LJF were calculated and compared. Results There were the significant differences in the growth and yield as well as the chlorogenic acid and galuteolin contents in different parts of LJF in different harvest seasons. Conclusion The best collection period is before and during the completely white flower bud stage, and the first batch flower buds have the highest yield and the best quality, followed by the second batch. Branches and leaves of LJF contain the higher levels of chlorogenic acid and galuteolin, which could be extracted and utilized.
