Objective: To establish HPLC fingerprints and spectrum-effect relationships of different batches of Filifolium sibiricum,clarify the contribution of the chemical constituents represented by the common peaks to the antimicrobial efficacy,and reveal the pharmacological basis. Method: Fingerprint was established by HPLC method with acetonitrile-PBS( 0. 1 mol·L~(-1) sodium dihydrogen phosphate and 2% acetic acid mixed 1 ∶ 1)as the mobile phase for gradient elution and the detection wavelength was 360 nm.
