Abstract: Objective: To set up the chromatographic fingerprint analysis method of different years and different parts of Paeoniae Radix Alba produced in Bozhou in order to provide the basis for scientific quality evaluation of Paeoniae Radix Alba and standard process. Methods: Kromasil C18 chromatographic column（ 250 mm × 4. 6 mm,5 μm）. Column temperature: 35 ℃. Detection wavelength: 230 nm. Injection volume: 10 μL. The flow rate: 1 m L·min-1. Mobile phase: acetonitrile（ A）-0. 01% phosphoric acid solution（ B）,gradient elution. Results: The paeoniflorin contents of different years and different prats of Paeoniae Radix Alba produced in Bozhou were accord with pharmacopoeia standard. The fingerprints of 10 batches samples had nine common peaks and the similarity were in 0. 992 1. 000. Conclusions: With the increase of growth period,the content of paeoniflorin and fingerprint principal component gradually decreased. The quality of Paeoniae Radix Alba produced in Bozhou over 2 3 years was better. Paeoniae Radix Alba produced in Bozhou over 2 3years can be harvested and fine root should be used as the medicine.
