| Abstract: |
| 【Objective】The study was conducted to understand the differences in volatile components of Pericarpium Citri Reticulatae （PCR） in different years.【Method】Xinhui PCR stored for 1 year（2017）, 5 years（2013） and 15 years（2003）were selected as research objects and the volatile components in PCR were analyzed by headspace solid phase microextraction （HS-SPME） combined with gas chromatography-mass spectrometry（GC-MS）.【Result】A total of 61 compounds were detected in PCR of 3 different storage years, and within a certain storage period, the types and contents of volatile components in PCR significantly changed with the extension of storage time. There were 34 volatile components in PCR stored for 1 year, 38 in PCR stored for 5 years. and 39 in PCR stored for 15 years. In the storage process of PCR, the relative contents of olefins and naphthalenes increased first and then decreased, the contents of esters, phenols and alcohols decreased first and then increased, and the content of aldehydes decreased year by year, while the alkanes were only detected in PCR in 2013.【Conclusion】During the 15 years from 2003 to 2017, with the extension of the storage time, the types of volatile components in PCR became more and more abundant, providing a more comprehensive theoretical basis for the saying that “Pericarpium Citri Reticulatae, the older the better”. |
