[Study on quantified relationship between contents of active components in Forsythia suspense and nutrition of soil].
OBJECTIVE
To sift the main effective factors of active component of Forsythia suspense.


METHODS
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.


RESULTS
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.


CONCLUSIONS
The contents of nutrition in soil is one of important factors which affect the active component of F. suspense.
