[Study on correlation of soil nutrients and content of active constituents in root of Rumex gmelini].
OBJECTIVE
To provide scientific basis for the selection of agrotype and property fertilization for Rumex gmelini cultivated in compliance with good agricultural practice (GAP).


METHODS
HPLC method was applied to determinate the content of seven active constituents (resveratrol, polydatin, chrysophanol 1-glucoside, nepodin, emodin, chrysophanol and physcion) of annual R. gmelini. And the correlation between soil nutrients and content of active constituents in the root of R. gmelini were analyzed by stepwise regression analysis.


RESULTS
Seven regression equation were established. The statistic significance was found in three of them.


CONCLUSIONS
The soil with high total K level is not suitable for R. gmelini cultivation. But the higher available N, available P, available K level of soil is suitable.
