目的:建立顶空毛细管气相色谱法同时测定4-雄烯二酮中甲醇和乙酸乙酯2种残留溶剂的分析方法。方法采用Agi-lent DB-624毛细管色谱柱(30 m ×0.32 mm ×1.8μm),FID检测器,以DMAC为溶剂。结果2种残留溶剂甲醇和乙酸乙酯在各自的质量浓度范围内呈良好的线性关系( r=0.9995和0.9994,n=7),2种残留溶剂甲醇和乙酸乙酯的回收率分别为101.7%和96.9%(RSD为2.04%和4.05%,n=9)。结论该方法操作简单、灵敏度高、适用范围广,适用于4-雄烯二酮中残留溶剂的检测。
目的:建立頂空毛細管氣相色譜法同時測定4-雄烯二酮中甲醇和乙痠乙酯2種殘留溶劑的分析方法。方法採用Agi-lent DB-624毛細管色譜柱(30 m ×0.32 mm ×1.8μm),FID檢測器,以DMAC為溶劑。結果2種殘留溶劑甲醇和乙痠乙酯在各自的質量濃度範圍內呈良好的線性關繫( r=0.9995和0.9994,n=7),2種殘留溶劑甲醇和乙痠乙酯的迴收率分彆為101.7%和96.9%(RSD為2.04%和4.05%,n=9)。結論該方法操作簡單、靈敏度高、適用範圍廣,適用于4-雄烯二酮中殘留溶劑的檢測。

Objective A capillary gas chromatography (GC) method with head-space sampling was established for the determination of residual solvents ,methanol and ethyl acetate in raw material drug of androstenedione .Methods Agilent DB-624 capillary col-umn(30 m × 0 .32 mm × 1 .80 μm) was used with FID as the detector and DMAC as the solvent .Results Linear responses were obtained for the 2 residual solvents in their respective ranges(r=0 .999 5 and 0 .999 4/n=7) .The average recoveries of three con-centration levels were 101 .7% and 96 .9% with RSD of 2 .04% and 4 .05% (n= 9) ,respectively .Conclusion The developed method is simple ,sensitive and accurate ,and can be used for the residual solvent analysis .
