Determination of linalool in Rhizoma Homalomenae by GC / 中成药

AIM: To establish the GC method for the determination of linalool of Rhizoma Homalomenae. METHODS:The column consisted of Fused Silica Capillary Polyethylene Glyol(30 m?0.25 mm?0.25 ?m),column temperature was at 120 ℃,Injection port temperature at 260 ℃,Detector temperature at 300 ℃,flow rate was 1.0 ml/min. RESULTS: Linalool has a good linearity in the range of 0.011 985～1.997 5 ?g.The recovery rate was 99.2%,RSD was 1.63%. CONCLUSION: The method developed is simple and accurate with good reproducibility,and can be used for quality control of Rhizoma Homalomenae.
