Technical Details & Test Data
- Identification
A. Infrared absorption spectrophotometry. Comparison: diosmin CRS.
B. Examine the chromatograms obtained in the assay.
Results: the principal peak in the chromatogram obtained with the test solution is similar in retention time and size to the principal peak in the chromatogram obtained with reference solution (a).
