ABSTRACT
Objective:
To establish HPLC method for the determination of loureirin A and loureirin B in Sanguis Draxonis Capsules.Methods:
HPLC system included C 18 reverse phase column and acetonitrile 1% acetic acid (34∶66) as mobile phase, detection at 280nm and external standard method.Results:
The standard curves of loureirin A was linear in the concentration range of 98~490ng, r =0.9996.The average recovery was 97.45%, RSD was 1.82%.The standard curves of loureirin B was linear in the concentration range of 43.2~259.2, r = 0.9993 .The average recovery was 96.92%, RSD was 1.57%.The contents of loureirin A and loureirin B in Sanguis Draxonis from heating free technology were higher than traditional technology.Conclusion:
This heating free technology is a new technique that is a creation with higher extract rate,this method is worth populariging.
