The Paeonia ostii T. Hong & J. X. Zhang seed shell, characterised by a high content of oligostilbenes, is one of the two most important by‐products in the preparation of seed oil. Oligostilbenes are considered characteristic constituents of the genus Paeonia , and can be used in fingerprinting to determine the geographical origin and the quality of raw materials. Objective To develop and optimise a simple and reproducible high‐performance liquid chromatography diode array detection (HPLC‐DAD) method for the simultaneous determination of seven oligostilbenes in P. ostii seed shell from different geographical areas, and to associate the cultivation area. Methodology A validated HPLC method coupled with a DAD detector was performed for the detection and determination of target compounds in the samples. Optimal chromatographic conditions were achieved using an Agilent Zorbax Eclipse SB‐AQ‐C18 column and a gradient elution with acetonitrile and potassium dihydrogen phosphate solution. Results The proposed quantitative method showed appropriate accuracy and precision, and was successfully applied to the routine analysis of seven oligostilbenes and the quality evaluation of 50 P. ostii seed shell samples. There were significant differences between the contents of the seven oligostilbenes in different samples ( P  < 0.01). Conclusion The results demonstrated that the oligostilbenes were main secondary metabolites in the P. ostii seed shells, and the content of seven components in P. ostii seed shells sourced from different cultivation areas in China was different.
