ABSTRACT

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.
