Quality analysis and evaluation of myrrh

Objective To establish the methods for the quality evaluation of Commiphora myrrha in different batches and provide the reference for quality control.Methods GC-MS and HPLC-PDA were used to analyze the volatile and non-volatile components,respectively.Similarity and principle components analysis(PCA) were carried out.Results Twenty-eight compounds were identified by GC-MS from C.myrrha and the HPLC fingerprint of non-volatile components was established.Results of similarity analysis showed that C.myrrha in different batches was different from each other except for batches from Hainan and Guangdong with high similarity.PCA demonstrated that sesquiterpenes,organic acid ester,and diterpenic acids played a leading role in the quality of C.myrrha.All results revealed that C.myrrha from Hainan had high qualities.Conclusion The established method could provide the guidance for quality control of C.myrrha.
