Abstract:
Objective: To establish HPLC method for determination of pterostilbene in Dragon's Blood with different extraction technology. Method: Applying a C 18 phase column and acetonitrile 1% acetic acid(41∶59) as mobile phase, detecting at 319nm and quantitating with external standard method. Results: The standard curves of pterostilbene was linear in the concentration range of 10.4～104ng, r =0.9992. The average recovery was 98.28%, RSD =1.97%. The content of pterostilbene in Dragon's Blood extracted with ordinary temperature was lower than that with heating technology. Conclusion: The content of pterostilbene extracted with ordinary temperature extraction in Dragon's blood have the advantage of heating extraction.
