Abstract:

We constructed high performance liquid chromatography (HPLC) fingerprint for Ramulus Cinnamomi to provide a new method for its quality evaluation and identification. We analyzed thirteen batches of Ramulus Cinnamomi with C18 column (Agilent Eclipse XDBC18 column), gradient elution solvent system including water and acetonitrile, flow rate of 0.8 mL/min, column temperature of 25℃ and detection wavelength of 285 nm. The method had better precision, repetition and stability. Thirteen shared peaks and four specific peaks exist in the thirteen batches of fingerprints. Similarity analysis shows that the quality of Guangdong and Guangxi samples has slight difference. HPLC fingerprinting will be a potential identification and quality evaluation tool for Ramulus Cinnamomi.
