Objective To prepare Cinnamomi Ramulus standard decoction and to study the quality standard of Cinnamomi Ramulus. Methods Fifteen batches of Cinnamomi Ramulus standard decoctions were prepared according to the standardization method. With cinnamon acid as the detection index, the transfer rate and extraction rate were calculated and the HPLC fingerprint analysis method was established. Results According to the measurement of 15 batches of standard decoctions, the transfer rate ranged from 56.93% to 94.06% and extractum rate was at the range of 3.30%—9.40%. Besides, the Similarity Evaluation System for Chromatographic Fingerprint of traditional Chinese medicine TCM (2012A) was used to analyze and compare the fingerprint, nine commom peaks were determined and four were calibrated including protocatechuic acid (peak 1), coumarin (peak 4), cinnamic acid (peak 6), and cinnamaldehyde (peak 7). Moreover, the similarity was over 0.95. Conclusion This study established an HPLC fingerprint analysis method of Cinnamomi Ramulus standard decoction. The method displays good precision, stability, and repeatability in fingerprint analysis. Therefore, this study has some identified significance and can provide a reference for the quality control of Cinnamomi Ramulus dispensing granules.
