篇名: | 乌芪舒筋通络片中乌头碱限量检测方法研究 |
TITLE: | |
摘要: | 目的:建立测定乌芪舒筋通络片中乌头碱限量的方法。方法:采用薄层色谱(TLC)法对制剂中的乌头碱进行鉴定。薄层 板为硅胶G薄层板,展开剂为甲苯-乙酸乙酯-三氯甲烷-丙酮-氨水(20 ∶ 18 ∶ 3 ∶ 6 ∶ 1,V/V/V/V/V),显色剂为稀碘化铋钾试液和亚硝酸 钠乙醇试液。经耐用性和检测限考察,并优选薄层板、温度和湿度。结果:乌头碱的TLC图斑点清晰且阴性对照无干扰。本试验 耐用性良好;检测限为0.9 μg;可用薄层板为Merck HPTLC预制板、硅胶G薄层板和自制的以羧甲基纤维素钠为黏合剂的硅胶G 薄层板;温度为5~16 ℃,湿度为32%~72%。结论:本方法操作简便、重复性良好,可用于乌芪舒筋通络片中乌头碱限量的测定。 |
ABSTRACT: | OBJECTIVE:To establish a method for the limit detection of aconitine in Wuqi shujin tongluo tablet. METHODS: TLC was conducted to identify the aconitine;TLC plate was silica gel G plate,developing solvent was toluene-ethyl acetate-chloroform- acetone-ammonia(20 ∶18 ∶3 ∶6 ∶1,V/V/V/V/V),chromogenic agent was bismuth potassium iodide test solution and sodium nitrite ethanol test solution;and durability investigation and detection limit detection were used to optimize the TLC plate,temperature and humidity. RESULTS:TLC showed the aconitine had clear spots and negative control without interference. The durability was good;detection limit was 0.9 μ g;available TLC plate was Merck HPTLC prefabricated plate,silica gel G TLC plate setf-made silica gel G TLC plate with adhesive of sodium carboxymethycellulose;temperature was 5-16 ℃ and humidity was 32%-72%. CONCLUSIONS:The method is simple and reproducibility,and can be used for the limit detection of aconitine in Wuqi shujin tongluo tablet. |
