ABSTRACT
Objective:
Hypericin content was determined in the extract of hypericum by dual-wavelength spectrophotometry.Methods:
The wavelengths were adopeted 589nm～647nm against a methanol blank.Results:
The linear correlation was observed within the range of 1.30～29.75?g/ml(r=0.9998). The average recovery of hypericin was 102.32%(n=6), RSD was 1.08%.Conclusion:
the result was exact, method was simple and convenient .
