目的:建立七味广枣胶囊的含量测定方法。方法:用气相色谱法对处方中丁香的指标成分丁香酚进行定量分析。采用10%PEG-20M Chromosorb WAW-DMCS(60~80)3 mm×2 m不锈钢柱;柱温:180℃;汽化室温度:230℃;气体流速:氮气50mL.min-1;氢气50 mL.min-1;空气500 mL.min-1;检测器:FID。结果:丁香酚进样量在0.77~10.88μg范围内呈线性关系(r=0.999 1)。平均加样回收率为99.2%(RSD=2.68%)。
Objective: To establish a method for determining the content of Qiwei Guangzao capsule. Methods: Quantitative analysis of eugenol, the index component of cloves in the prescription, was performed by gas chromatography. 10% PEG-20M Chromosorb WAW-DMCS (60-80) 3 mm×2 m stainless steel column; column temperature: 180°C; vaporization chamber temperature: 230°C; gas flow rate: nitrogen 50 mL.min-1; hydrogen 50 mL .min-1; Air 500 mL.min-1; Detector: FID. RESULTS: The linearity of the eugenol injection ranged from 0.77 to 10.88 μg (r=0.999 1). The average recovery was 99.2% (RSD=2.68%).
