Objective: To build UV fingerprint of different polar parts from root and stem of Gentiana rigescens and analyze difference of spectral characteristics among eight cultivation patterns. Method: UV data of samples was finished by UV spectrophotometry

data was processed by four print smooth and first orders.Similarly evaluation of UV fingerprint of G. rigescens medicinal materials from different cultivation patterns was finished by common peak ratio and variation peak ratio dual index sequence analysis.Discriminant analysis was used to evaluate discriminate ability of UV fingerprint data for cultivation pattern of G. rigescens. Result: Fingerprint of samples from eight cultivation patterns were lower similarly at 221-247 nm.Chemical polarity fingerprint of different samples

cultivated by same method

was different too.There were significant fingerprint characteristic.UV fingerprints were similar between G. rigescens which grown on slope of valley and which cultivated under Chaenomeles sinensis.However

chemical compounds were significant different between plant grown on slope of valley and which cultivated under Alnus nepalensis.Discriminant analysis showed that about 90% sample could be discriminated according to cultivation patterns. Conclusion: UV fingerprint of different polar parts from root and stem of G. rigescens can help to discriminate cultivation patterns of medicinal materials.
