Study on Chemical Components for Volatile Oil from Polygonum Flaccidum Messin

OBJECTIVE The Polygonum flaccidum Messin is a kind of tradition inside herb medicine of China,having good foreground of development in plant source agrochemical, medicine, food additive et al. The purpose of this study from the molecular level understanding of its chemical composition of active ingredients for a more rational development and utilization of these resources.METHODS The volatile compounds of Polygonum flaccidum Messin were isolated with steam distillation,and identified by capillary GC／MS and the relative contents of the constituents were determined by area nomalization method． RESULTS Fifty volatile components were identified and determined，accounting for 97.84% of the total area of the peaks.CONCLUSION The main volatile compounds are: N-(2-Aminoethyl)aziridine,3,4,5,6-Tetrahydrophthalic anhydride,3-Hexene-1-ol,Hydrogen chloride,2-Methy-2-tert-butyl-1,3-dithiane,1-Methyl-7-oxoheptyl 2-formyl-4,6-dimethoxybenzoate,Thieno3,2-ebenzofuran,Phosphoric acid, diundecyl methyl ester,Phenanthrene, 9-ethyl,Methyl hydrogen disulfide,Cyclopropene,1-bromotrifluoro,2-4-(Dimethylamino)phenyl-3-hydroxy-4H-chromen-4-one
