[Determination of tetrandine content in tetrandine microsphere].
OBJECTIVE
To determine the contents of tetrandine in tetrandine microsphere for the quality control of the preparation.


METHODS
Tetradine in microsphere was determined by spectrophotometry of standard curve.


RESULTS
The content of tetrandine was 44.5% +/- 0.26% (n=3).


CONCLUSIONS
The method was simple, rapid and accurate.
