Abstract

Objective: To optimize the extraction methods and GC-MS analysis of volatile oil in Rhizoma Zingiberis.Methods: The distilled water volume,ultrasonic time,soaking time and extraction time were optimized by orthogonal design and GC-MS chromatogram was obtained.Results:The yield of volatile oil was 1.89% by orthogonal design.Also,a stable,reliable chromatogram was obtained under optimized GC-MS conditions.Conclusion:The design can be applied for optimizing the extraction condition of volatile oil in Rhizoma Zingiberis and 49 compounds were identified by GC-MS analysis.
