[Determination of cholesteryl palmitate in Oviductus Ranae by HPLC].

OBJECTIVE
To develop a new method for the determination of cholesteryl palmitate in Oviductus Ranae.


METHOD
A HPLC method was set up, using Zorbax Silica column and cyclohexane-diethyl ether (40:1) as mobile phase with a flow rate of 1.0 mL x min(-1), and the UV detection wavelength was 203 nm.


RESULT
The calibration curve was linear over the range of 0.60-8.92 microg (r = 0.9997), the average recovery of the method was 98.4%. RSD 1.8% (n = 6).


CONCLUSION
The results showed that method was reliable and accurate.
