ABSTRACT: Lonicerae japonicaeFlos (LJF)
is widely used in traditional Chinese medicines for the treatment of various
diseases, which is now in great demand every year and has a broad development
prospect. However, the flowering phase of common LJF varieties is so short, which
seriously restricts the development of LJF industry. As a new cultivated kind
of Lonicerae japonicae Flos, “Hua Jin
6” has characteristics in long flowering phase and conveniently picking, which makes
it have a broad development prospect. The aim of this study is to provide scientific
guidance for its suitable harvest period by measuring yield and quality of “Hua
Jin 6” from different harvest time. Studies show that flower size had a slowly
rising trend from the first day to the seventh day, and then slowly declined or
kept stable. There were no significant differences of total phenolic acid
contents in different samples from different days, but contents of total flavonoids
were on the rise and up to maximum in the ninth day. The contents of total
iridoids had an increasing tendency from the first day to the fifth day and
then kept relatively stable in other days. We demonstrated that the quality of “Hua
Jin 6” is relatively stable and suitable for harvesting in all flower buds
white stage in term of HPLC fingerprints. Our findings can make it possible to
select the suitable time for different harvest purpose.
