[Determination of linarin in Yuye Jiedu granule by RP-HPLC].
OBJECTIVE
To determine the content of linarin in Yuye Jiedu granule.


METHODS
A HPLC method was developed. The chromatographic conditions are as follows Luna C18 column and acetonitrile-0.05 mol x L(-1) phosphate buffer-phosphoric acid (30:70:0.06) as mobil phase, detection wavelenth at 327 nm.


RESULTS
The linear range of linarin was 0.025-0.50 microg. The average recovery was 98.7% and RSD 2.7%.


CONCLUSIONS
The method is simple and accurate, with good repeatability, and can be used for determination of linarin in Yuye Jiedu granule.
