[Study on the dynamic change of flavonoids content in Mentha haplocalyx].
OBJECTIVE
To determine the dynamic change of total flavonoids and its main aglycone and glycoside content in Mentha haplocalyx Briq.


METHODS
Using UV-VIS spectrum and HPLC method for the total flavonoids and its aglycone and glycoside.


RESULTS
The accumulation of flavonoids showed a regular pattern.


CONCLUSIONS
The contents of total flavonoids and its main aglycone and glycoside are highest in the traditional harvesting time.
