山合欢皮药材质量标准初步研究

Study on the Preliminary Quality Standards of Albizia kalkora (Roxb.) Prain

目的:初步建立山合欢皮药材质量标准。方法:对山合欢皮药材进行性状鉴别、显微鉴别,采用薄层色谱法,以(-)-丁香树脂酚-4-O-β-D-呋喃芹糖基-(1→2)-β-D-吡喃葡萄糖苷为对照,建立定性鉴别方法;对山合欢皮药材的水分、总灰分、水溶性浸出物含量进行测定。结果:薄层色谱斑点分离好,斑点清晰,专属性强;初步预定山合欢皮药材水分不得超过14.0%;总灰分不得超过6.0%;水溶性浸出物不得少于7.0%。结论:本法操作简单、结果可靠,可为山合欢皮质量控制提供实验依据。

Objective To establish the Preliminaryquality standards for Albizia kalkora (Roxb.) prain. Methods Morphological identification and microscopic identification of Albizia kalkora (Roxb.) prain.were made.(-)-Syringaresnol-4-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside in it was qualitatively identified by TLC.The water content,total ashes,water-soluble extractives were determinde. Results TheTLC spots were separated well 、clear and had a strong specificity. It was initially proposed that the content of moisture was at most 14.0%,total ash was no more than 6.0%,water-soluble extractives as at least 7.0%. Conclusion The method is simple,reliable and can effectively control the quality of medicinal materials.
