The accurate identification of pericarp and tangerine peel and the progress in the study of their scientific connotation

"Good medicine, good medicine" Good medicine is the fundamental guarantee of high efficacy and high safety The formation of genuine medicine is closely related to its own unique chemical composition Tangerine peel is the dry and mature peel of Rutaceae plant orange and its cultivated varieties, which is mainly divided into tangerine peel and pericarp of Guangchen, which is mainly produced in Xinhui District, Jiangmen City, Guangdong Province, and is regarded as authentic medicine The accurate identification of pericarp and tangerine peel and the connotation of their authenticity have always been the focus and difficulty of research With the support of the national key research and development plan "modernization research of traditional Chinese medicine" key special project "large scale ecological planting of Southern medicine and its targeted poverty alleviation demonstration research", the team of Southern medicine tangerine peel (composed of some experts from Sun Yat sen University, China Pharmaceutical University and Guangzhou Medical University) has been in analytica chimica Acta and Journal of chromatography respectively this year B magazine published a paper, through the first established metabonomics, DNA barcode and electronic nose method, identified 9 species-specific chemical markers, including 6 flavonoid glycosides and 3 polymethoxyflavones, including chazhi orange (Pericarpium Citri Reticulatae) and other cultivars of pericarp (pericarp citri Reticulatae); the research further clarified that 2-methylamino-benzoic acid methyl ester can be used to effectively distinguish pericarp Reticulatae Reticulatae Reticulatae from pericarp Reticulatae Reticulatae Reticulatae A sign of leather In addition, the research also found that the characteristic polymethoxyflavonoid components in Pericarpium Citri Reticulatae, such as chuanchensu, 3,5,6,7,8,3 ′, 4 ′ - heptanoxyflavone, have the anti NPC and hypoglycemic activity The related research results have been published in the Journal of Food Science & Nutrition this year, and obtained the patent authorization for invention These results, based on the analysis of the chemical basis of the whole cortex grandiflorum, are helpful to establish a new model and method for the quality evaluation of cortex grandiflorum based on the weight of efficacy and help to analyze the material basis essence of the authenticity of cortex grandiflorum
