摘 要:目的:建立同时测定鸡骨草总黄酮碳苷提取物中8种大孔吸附树脂残留物的顶空气相色谱分析方法。方法:采用Supelco-wax毛细管柱(30m×0.25ram×0.25μm),体积分数为50%的N,N-二甲基甲酰胺(DMF)为溶解介质,高纯氮作为栽气,FID检测器;进样口温度210℃,检测器温度230℃,柱温先在70℃维持8min,再以10℃/min的速度升至220℃,维持7min。结果:在以上色谱条件下,各组分在所考察的浓度范围内均具有良好的线性,r为0.9965~0.9999,RSD为1.839%~9.155%,苯、正己烷、甲苯、间二甲苯、邻二甲苯、对二甲苯、二乙烯苯及苯乙烯的最低检出浓度分别为0.05、0.25、0.1、0.1、0.1、0.1、0.2、0.1μg·mL-1。结论:该法快速、灵敏、准确,适用于鸡骨草总黄酮碳苷提取物中大孔吸附树脂残留物的测定。Objective:To establish a headspace GC method for simultaneous determination of the eight kinds of macroporous resin residues in total flavonoid C-Glycosides extracts of Abrus mollis. Methods: The determination was performed on Supelco-Wax N, N-dimethylformamide(DMF) and the detector was FID; temperature column(30m × 0.25mm × 0.25μm). The solvent medium was 50 % , The injector was, the detector temperature was 230℃, and carrier gas was high-purity nitrogen. The column temperature was changed according to the program:initial temperature was kept at 70℃ for 8min, then raised to 220℃ at the rate of 10℃/rain, and maintained for 7min. Results. The results showed good linearity (r=0. 996 5-0. 999 9),and relative standard derivations (RSD) of precision were in the range of 1. 839 %-9. 155 %. The minimum detection concentrations of benzene, n-hexane, Methyl benzene, m- xylene, o-xylene, p-xylene,divinylbenzene and styrene were 0.05,0.25, 0.1, 0.1, 0.1, 0.1, 0.2and 0. lμg . mL-1 ,respectively. Conclusion : The method is simple, sensitive and accurate. It is suitable for determination of macroporous resin residues in total fla vonoid C-Glycosides extracts of Abrus mollis.
