艾粉质量标准初步研究

[目的]初步研究不同批次的艾纳香提取物艾粉质量标准。[方法]取来自贵州不同地区49批艾粉(艾纳香提取物)为研究材料,对其外观形状进行观察描述,测定其溶解性、含水量等物理特性,采用薄层层析法(TLC)进行定性分析以及GC指纹图谱进行相似度评价。[结果]艾粉为白色、块状、盐粒状或颗粒状结晶,手捻不易碎,具清香气,味辛、凉,具挥发性,几乎不溶于水,易溶于乙醇、乙醚、氯仿,艾粉含水量不高于24%为宜。艾粉样品中l-龙脑TCL斑点清晰,β-石竹烯、花椒油素显相同颜色的斑点或没有斑点,分离良好。GC指纹图谱仅得到2个共有峰,确认为有效成分l-龙脑和樟脑,相似度基本都在0.9以上。[结论]该研究结果为艾粉在生产过程中的质量控制提供参考依据,同时进一步促进高质量天然冰片的生产。

Preilm inary D evelopment of Quail ty Stan dard for Aifen

[Objective]To make a preliminary development of quality standard for Aifen [the extract powder of Blumea Balsamifera (L.) DC.] .[Method ] Forty-nine batches of Aifen collected from different regions in Guizhou were used as research materials for this study.The appearance traits was observed and described, the solubility and water content were determined.TCL was used for qualitative analysis and sim-ilarity evaluation was obtained by GC fingerprint.[ Result] Aifen was white, blocky,salt granular and granulate .It was unbreakable by hand twist.Aifen was volatile with fragrant smell and tasted sheen and cool .It was almost insoluble in water, but easily dissolved in trichlorometh-ane , ethanol, diethyl ether.Its water content should be no more than 24%.TLC spots of l-borneol were clear in those Aifen samples.β-caryophyllene and xanthoxylin appeared the same color spots or no spots.The three components all separated well.Only two common peaks were collected in the fingerprint and confirmed to be l-borneol and camphor.The similarities between the entire chromatographic profiles of Aifen samples were basically all all over 0.90.[Conclusion] This study will provide reference and basis for the quality control of Aifen in the production process.Meanwhile, it will further promote the production of high-quality natural borneol.
