ABSTRACT OBJECTIVE To establish HPLC fingerprint of Rheum palmatum before and after steaming with wine，and to
determine the contents of 3 differential components. METHODS HPLC method was used to establish the fingerprints of 15 batches
of R. palmatum（before wine-steaming）and prepared rhubarb（after wine-steaming）and the similarity evaluation was conducted.
The chemical pattern recognition analysis was carried out by principal component analysis，cluster analysis，partial least squares-
discriminant analysis and orthogonal partial least squares-discriminant analysis. The contents of gallic acid，resveratrol-4′-O-
glucoside and resveratrol-4′-O-（6″-galloyl）-glucoside in 30 batches of samples were determined. RESULTS In the fingerprint
study，48 common peaks were demarcated for R. palmatum and 47 for prepared rhubarb as well as 17 common peaks were
identified by reference substance. Cluster analysis and principal component analysis showed that R. palmatum derived from Qinghai
before and after steaming with wine could be distinguished from those from Sichuan and Gansu. The results of content
determination showed that the contents of 3 differential components in R. palmatum derived from Qinghai before and after steaming
with wine were higher than those from other two production areas；the contents of gallic acid in prepared rhubarb derived from
those production areas were higher than R. palmatum；the contents of resveratrol-4′-O-glucoside and resveratrol-4′-O-
（6″-galloyl）-glucoside in R. palmatum derived from those production areas were higher than prepared rhubarb. CONCLUSIONS
Fingerprint and content determination method established in this study can quickly，scientifically and accurately evaluate the quality
of R. palmatum from different producing areas before and after wine steaming，which provide a basis for the processing
specification and quality control of R. palmatum.
