[Determination of 5F in Pteris semipinnata L. from various origins by TLC-scanning].
OBJECTIVE
To determine the content of 5F in Pteris semipinnata L. from various origins.


METHODS
5F was determined by TLC-Scanning.


RESULTS
The linear relationship was in range of 0. 504 - 2. 520 microg. The mean recovery was 96. 68% and RSD = 1.24% (n = 5).


CONCLUSIONS
The method is available with a good reproducibility, and pretreatment is simple and easy to operate.
