连翘有效成分含量与土壤养分的量化关系研究

Study on quantified relationship between contents of active components in Forsythia suspense and nutrition of soil

目的:筛选影响连翘有效成分的主导土壤因子。方法:采用HPLC测定老翘和种子中有效成分的含量,常规方法测定连翘产地土壤养分的含量,应用SPSS统计软件对不同产地连翘有效成分的含量和土壤养分的含量进行统计分析,计算各土壤养分因子与连翘有效成分含量的偏相关系数,建立连翘有效成分含量与土壤养分因子的多元回归方程。结果:连翘种子中连翘酯苷含量的最大影响因子是土壤有效磷,其次为土壤有效钾,pH,FACT;种子中连翘苷含量主要受到有效钾,FACT的影响;影响老翘中连翘酯苷含量的主导因子有全磷、有效钾和FACT;影响老翘中连翘苷含量的最大因子为土壤pH,其次为土壤有效磷、有效钾和FACT。结论:土壤养分因子是影响连翘有效成分的重要因素。

Objective： To sift the main effective factors of active component of Forsythia suspense. Method： The active component of F. suspense was mensurated by HPLC, and the contents of nutrition in soil was determined by conventional methods. The active component of F. suspense and the nutrition of soil collected from different regions was analyzed by SPSS 11.0 for windows software package. Accounted the partial correlation coefficients of soil factor to the active component of F. suspense, and established regression equations. Result： Soil available phosphorus is the most important factor that effected forsythiaside content in the seeds of F. suspense, followed by kalium, pH, FACT; Forsythin in the seeds of F. suspense is mainly effected by soil abailable kalium and FACT; pH is the important factor effected Forsythinin in F. suspense, followed by soil available phosphorus, soil available kalium, and FACT; and the main effectivefactors of forsythiaside in F. suspense are soil available phosphorus, soil available kalium. Conclusion： The contents of nutrition in soil is one of important factors which affect the active component of F. suspense.
