Objective: To investigate effects of different drying methods on composition and content of volatile oil from Angelicae Sinensis Radix. Method: Volatile oil was extracted by steam distillation

Angelicae Sinensis Radix was dried by dry in the sun

dry in the shade

stoving at 40 ℃ and 60 ℃

chemical constituents in volatile oil were analyzed by GC-MS. Result: Content of volatile oil was the highest in Angelicae Sinensis Radix with 40 ℃ oven-drying(1.074%) and shade drying(1.165%);Forty compounds in volatile oil from Angelicae Sinensis Radix dried different methods were identified;After dried by different methods

main ingredients in volatile oil was basic the same

but the content of each component vary enormously. Conclusion: Different drying methods had marked influence on composition and content of volatile oil from Angelicae Sinensis Radix

40 ℃ oven-drying should be adopted.
