[Qualitative identification and quantitative determination of naringin in rhizoma Drynariae by TLC].
OBJECTIVE
To set up the method for the qualitative identification and quantitative determination of naringin in Rhizoma Drynariae.


METHODS
TLC and TLC-scanning.


RESULTS
Naringin in Drynariae fortunei was identified by TLC and its content was 0.73%.


CONCLUSIONS
The TLC identification has been proved to be convenient, and the quantitative determination by TLC-scanning has been proved to be accurate, reliable and of good reproducibility, the recovery rate being 100.48% and RSD 1.37% (n = 5).
