Objective:Based on the experimental data of thermal analysis, the characteristic parameters of combustion pyrolysis of myrrh were obtained, and the internal evaluation system of myrrh was established.And to Investigate the pyrolysisScharacteristics of myrrh and its relevantSmixture. Methods: the pyrolysis properties of myrrh and its relevantSmixture were studied by thermogravimetry and thermogravimetric TG-DTG technique. Results: According to the characteristics of burning pyrolysis of myrrh, The pyrolysis rate peaks of myrrh at 286.20±10.32℃ and 460.72±11.09℃ were 3.13±0.13%.min-1 and 4.68±0.63%.min-1 respectively were the pyrolysis characteristics of myrrh, at 412.9±86.4℃appeared the thermogravimetric rate peak may be related to the impurities contained in it.The specific temperature of this product was 145.17±2.72℃.The addition of vinegar reduces the temperature of the maximum thermogravimetric rate of the pyrolysis of the volatile oil in reverse proportion, which causes the volatile oil to be easily lost, and shortens the time required for the pyrolysis of the volatile oil in a reverse proportion, which results in the accelerated pyrolysis of the essential oil, and decreases the total acid pyrolysis in a positive proportion. As a result, the total acid content is preserved. The specific processing temperature and time of this product are 145.17±2.72℃ and 12.37±1. 60 min. It was found that there was a good linear relationship between myrrh and its vinegar ratio. The range of R2 of myrrh and vinegar was 0.887±0.051 and 0.929 ±0.019,respectively, which proved the feasibility of using Page model to verify the processing of Chinese medicinal materials. Conclusion: In this paper, the characteristic parameters of combustion pyrolysis used to identify high quality myrrh were established by using thermal analysis technique, which provided scientific and reasonable quality identification of myrrh. It lays a theoretical foundation for specific application and related research, combined with processing excipients and this paper deduces and quantifies the processing technology (starting and end point temperature). The scientific connotation of Chinese myrrh and vinegar was explained.
