[Study on the chemical changes of whole constituents in the preparing process of kansui root].
OBJECTIVE
To study the chemical changes of whole constituents in the preparing process of kansui root in order to uncover the mechanism of detoxication in preparing process.


METHODS
The raw and prepared kansui were extracted with water and methanol and analyzed with HPLC respectively.


RESULTS
Seven constituents disappeared in the prepared kansui and four new consitituents were produced in the water extracts. The concentration of four other constituents decreased. In the methoanol extract, two constituents disappeared and one constituent produced during preparing process. The concentration of six other constituents increased in the methanol extracts.


CONCLUSIONS
The mechanism of detoxication of kansui root preparing process is may be that the toxic constituents decomposing or water solubility reducing.
