Establishment of HPLC Fingerprints Analysis Procedure for Flue-cured Tobacco in Yunnan

Choosing an appropriate method to classify tobacco quality is of significance for improving the quality of tobacco product. This study established a standardization procedure of HPLC fingerprint analysis for Yunnan flue-cured tobacco. The technology included four main parts, i.e., the sampling and sample processing, the selection of feature extraction agents, instrumentation, and fingerprint database building. The study proposed the concept of time-sharing database of flue-cured tobacco fingerprints and its building method. The fingerprint technology could be applied for classification and controlling of the quality of tobacco.
