[Objective] The experiment aimed to inquire into the regular pattern of the flavonoids content in erect type Ophiopogon jaonicus preliminarily.[Methods]In the main Ophiopogon jaonicus-producing area,we use the method of home position dynamic method to gather sample for experiments,use UV to determine the flavonoids content in Ophiopogon jaonicus and use correlation and regression method to analyze the relation between flavonoids content and the growth period of Ophiopogon jaonicus.[Results]The relation between flavonoids content(y1)and the growth period(x∥d)of erect type Ophiopogon jaonicus is:y=1.235 6lnx-4.748 9(n=7,50≤x≤730,0≤y≤3.128,r0.001=0.950 7,r=0.954 2).[Conclusion]During a determinate time(50≤x≤730),positive correlation exists between flavonoids content and the growth period of Ophiopogon jaonicus.Our research has a great importance in directing the scientific harvest and GAP production of erect type Ophiopogon jaonicus.
