直立型川麦冬黄酮含量变化规律的初步研究

目的]初步探讨直立型川麦冬黄酮含量的变化规律。方法]在川麦冬主产区,采用原位动态法采集供试品,硫酸-苯酚比色法测定麦冬黄酮含量,相关回归法分析麦冬黄酮与生育时间的变化规律。结果]直立型川麦冬中的黄酮含量y(mg/g)与生育时间x(d)的变化规律是:y=1.2356 lnx-4.748 9(n=7,50≤x≤730,0≤y≤3.128,r0.001=0.9507,r=0.9542)。结论]在一定生育时间范围内(0≤x≤730 d),直立型川麦冬中的黄酮含量y(mg/g)与生育时间x(d)呈极显著的正相关关系。

Preliminary Research of the Regular Pattern between Flavonoids Content and the Age of Erect Type Ophiopogon jaonicus

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 contenty(mg/g)]and the growth period 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.
