| Abstract: | Objective To establish a HPLC method for determination of the content of catechin in Songling- Xuemaikang capsules. Methods The analysis was performed on Alltima C18 column (250 mm × 4.6 mm, 5 μm) with mobile phase consisting of methanol (A) -l% Acetic Acid (B) for gradient elution. The flow rate was 1 ml/min and the column temperature was 25 ℃. Results The results showed that catechin was well separated with the good linearity in 0.00756-0.05040 μg/μl. The average recovery of catechin was 100.147%. Conclusions The method could be applied to determine catechin in Songling-Xuemaikang capsules, which would make sure the quality control of capsules. |
