Analysis of the Volatile Oil from Lithospermum erythrorhizon and Arnebia euchroma by GC-MS / 中国药房

ABSTRACT

OBJECTIVE:To analyze the volatile oil extracted from the root of Lithospermum erythrorhizon and Arnebia euchroma.METHODS:Volatile oil were extracted from L.erythrorhizon and A.euchroma by steam distillation and determined by GC-MS.RESULTS:34 components and 36 components of volatile oil extracted from the root of L.erythrorhizon and A.euchroma were separated and identified respectively,accounting for 70.16% and 74.79% of the total peak area.There were 4 kinds of common peak among these components.The main components were 2,6-di-tert-butyl-p-Cresol(9.29%),2,4-di-t-butyl-1,3-Pentadiene(8.17%),and trans-Nerolidol(6.05%) in L.erythrorhizon and muscalure(16.28%),3-Allyl-2-methoxyphenol(6.20%)and camphor(5.82%) in A.euchroma.CONCLUSION:The study can provide scientific basis for the further development of Radix Arnebiae.
