Abstract: [Objective] Discuss and ensure the suitable harvest time of Lonicerae japonicae Flos new variety "Huajin 6". [Method] Collecting flower buds from different harvest time, including three green stage, two white stage, big white stage, bud morphological characteristics such as size and weight index of different harvest of Lonicerae japonicae Flos new variety "Huajin 6" were measured by vernier caliper and electronic balance;The contents of chlorogenic acid and luteoloside were measured by HPLC. [Results] From three green stage to big white stage, the appearances of Lonicerae japonicae Flos "Huajin 6" change obviously, bud length, diameter and dry weight were on the rise from 0.17 cm, 2.05 cm, 0.19 g to 0.24 cm, 2.80 cm, 0.25 g respectively;During second days to eleventh days of big white period, bud length, diameter and dry weight tended to stable;During three green stage to big white stage, the content of chlorogenic acid was significantly declined from 33.59mg/g to 24.32mg/g, the content of cynaroside increases significantly from 0.55 mg/g to 0.95 mg/g. During the second days to eleventh days of big white period, the content of luteoloside kept rising until to 1.93mg/g and the content of chlorogenic acid had no significant changes during the second days to eleventh days of big white period. [Conclusion] The dry weight and the contents of chlorogenic acid and cynaroside of Lonicerae japonicae Flos "Huajin 6" are relatively stable in the whole big white stage, considering the consistency and appearance of the bud, this study thinks that Lonicerae japonicae Flos "Huajin 6" can be picked during the whole period.
