Abstract:
Objective To study the fingerprint determination method of Pogostemon cablin by HPLC.Methods A RP-HPLC method was established with the mixed solution of methnol and 0.1 % acetic acid aqueous solution as mobile phase(gradient elution),flow rate at 1.0 mL/min,detection wavelength at 254 nm,analytic time being 50 min and column temperature at 25 ℃.Results The results of comparative analysis of 10 batches samples showed that 15 common peaks were shared by Pogostemon cablin.The common peaks were classified to two regions and the second was the main characteristic region which had an amount of characteristic peaks.All samples had the similar fingerprint features.Conclusion The method is accurate,repetitive and can be applied for the identification and quality control of Pogostemon cablin.
