白蚁巢胶囊的质量评价

摘要

目的：对白蚁巢胶囊的质量进行评价。方法：对不同批次白蚁巢胶囊的水分、浸出物、总灰分、酸不溶性灰分、总氮、重金属进行测定；以亮氨酸为指标，采用薄层色谱法进行定性鉴别；采用氨基酸分析仪测定15种游离氨基酸的含量；采用高效液相色谱法测定黄曲霉毒素的含量；采用气相色谱法测定9种有机氯农药残留量；采用原子荧光光度计测定汞的含量。结果：薄层色谱斑点清晰，分离度好；15种氨基酸的平均含量为1．4948～9．2520 mg・ g－1；未检测到黄曲霉毒素；有机氯农药残留量为0．0284～0．0310μg・ g－1；汞含量为0．0535～0．1056μg・ g－1。结论：各项指标均符合白蚁巢胶囊的试行质量标准和《药用植物及制剂出口绿色行业标准》的规定。%Objective: To evaluate the quality of Termites Nest Capsules.Methods: The items: water content, extract, ash, acid-insoluble ash, total nitrogen and heavy metal for different batches of Termites Nest Capsules were determined.The marker Leu was identified by qualitative TLC.The contents of 15 kinds of free amino acids were detected by amino-acid analyzer.The de-termination of aflatoxin was conducted by HPLC.GC was performed to determine 9 kinds of organochlorine pesticides and the con-tent of mercury was measured by atomic fluorescence.Results: Identification spots of TLC characteristics were clear whth good resolution.The average contents of 15 kinds of free amino acids, organochlorine pesticides and mercury in the samples were 1.494 8-9.252 0 mg・ g -1 , 0.028 4-0.031 0 μg・ g -1 and 0.053 5-0.105 6 μg・ g -1 , respectively.Aflatoxins was not detected.Conclusion: The results are consistent with the quality standard and“export standard of medicinal plants and prepara-tion of green industry”.
