Processing of Citri Reticulatae Pericarpium： A Review / 中国实验方剂学杂志

ABSTRACT

Citri Reticulatae Pericarpium is a commonly used traditional Chinese medicine in China. By referring to herbal monographs and related research documents， and comparing all editions of Chinese Pharmacopoeia and local processing specifications， the processing history， modern processing specifications， study on chemical constituents and pharmacological effects before and after processing of Citri Reticulatae Pericarpium were summarized. It was found that the processing methods of Citri Reticulatae Pericarpium in the past dynasties were mainly cleansing， cutting and frying. The processing methods of Citri Reticulatae Pericarpium included in all editions of Chinese Pharmacopoeia were all cleansing and cutting. In modern local processing specifications， there were mainly processing methods such as frying， steaming and carbonizing. The components of Citri Reticulatae Pericarpium were mainly volatile oil and flavonoids. After processing， the total amount of volatile oil generally decreased， and the contents and compositions of volatile oil and flavonoids also changed. It may be the main reason for the difference of efficacy before and after processing. At present， the optimization of processing technology of Citri Reticulatae Pericarpium mainly focuses on steaming， processing with vinegar and baking. Pharmacological research on Citri Reticulatae Pericarpium mainly focuses on reducing blood lipid， relieving cough， relieving asthma and resolving phlegm， and inhibiting pulmonary fibrosis. The current research on the processing methods of Citri Reticulatae Pericarpium is not in-depth enough， the material basis of many processing methods has not been clarified， and the research on the efficacy before and after processing is not in-depth enough. Further research is needed to clarify the material basis and mechanism after the processing of Citri Reticulatae Pericarpium， so as to standardize the processing method and establish specific quality standards.
