Résumé
Piper longum is the immature ear of Pepper family of Papper. Although P. longum is used to treat gastrointestinal diseases in traditional Chinese and Mongolian medicines, there are significant differences in compatibility and treatment of diseases. In this paper, the traditional Mongolian medicine P. longum in Chinese usage, taste, function, and clinical compatibility research were analyzed and compared. Through literature research and statistical analysis, we would sort out the records of P. longum in Chinese materia medica and Mongolian materia medica, combined with computer software analysis, analyze the frequency of use in clinical medicine P. longum and drug law; This review introduced the progress of research on chemical constituents and pharmacological activities of P. longum compatibility as well as in clinical medicine in the Chinese, hoping to provide the basis for the application of P. longum in the field of traditional Chinese and Mongolian medicines.
Résumé
Objective To observe the free radical scavenging action of volatile oil from Piper longum L.growing in Hainan Province and to explore the relationship of the action with molecular structure.Methods 1,1-Diphenyl-2-picrylhydrazyl radical(DPPH) method was used to determine the scavenging action.The components of volatile oil were analyzed by GC-MS,and their molecular structures were identified by databank.Results(1)The volatile oil from Piper longum L.had scavenging actions on free radicals in a concentration-dependent manner.(2)Forty one compounds were found in volatile oil from Piper longum L.growing in Hainan Province,in which the amount of carbon-carbon double bond(C=C) was in predomination.Conclusion Carbon-carbon double bond(C=C)is the essential functional group for free radical scavenging action of volatile oil from Piper longum L.
