Analysis of the Essential Oil Compositions in Atractylodes Lancea / 中国药房

ABSTRACT

OBJECTIVE: To analyze the chemical compositions of the essential oil from the rhizomes of Atractylodes lancea and determine their relative contents.METHODS:The essential oil was extracted from the rhizomes of Atractylodes lancea by steam distillation method.GC-MS multiple techniques were applied to isolate the constituents and identify their structures.RESULTS: 44 constituents were isolated and 33 of them were detected.The main compositions in the essential oil were ?-eudesmol,Atractylon,Hinesol and Atractylodin.Computed by area normalization method,the contents of the four compositions were 18.894%,13.707%,11.053% and 6.815%,respectively.CONCLUSION: This experiment is conducive to the correct evaluation of the quality of the cultivated Atractylodes Lancea
