【摘 要】 目的:对网果酸模进行质量标准研究。方法:建立网果酸模的性状、显微及薄层鉴别方法,并按《中国药典》2015 年版有关规定对水分、灰分和酸不溶性灰分等项目进行了测定。结果:网果酸模的薄层色谱中,在与对照品色谱相同位置上显相同颜色的荧光斑点。水分、总灰分、酸不溶性灰分、醇溶性浸出物范围分别为 5.60%~6.58% 、4.00%~7.26% 、0.96%~3.93% 、18.94%~25.94% 。结论:该标准可用于网果酸模药材的质量控制。

Abstract:Objective To study the quality standard of Rumex chalepensis Mill.. Methods Establish the identification, microscopic and thin layer identification methods of Rumex chalepensis Mill., and determine the items of moisture, ash and acid-insoluble ash according to the relevant provisions of the 2015 edition of the Chinese Pharmacopoeia. Result In the thin layer chromatography of Rumex chalepensis Mill., fluorescent spots of the same color appeared at the same position as the reference substance chromatography. The range of moisture, total ash, acid-insoluble ash and alcohol-soluble extractives are 5.60%~6.58%, 4.00%~7.26%, 0.96%~3.93%, 18.94%~25.94% respectively. Conclusion The standard established by the institute can be used for the quality control of Rumex chalepensis Mill..

網果酸模为蓼科酸模属植物网果酸模Rumex chalepensis Mill.的干燥根及根茎,始载于《中药志》,又名红丝酸模、金不换,主要分布在湖北、江西、河南、浙江及安徽等地[1-3],味苦性寒,具有清热解毒、通便、杀虫之功效,民间用于止血和治疗痢疾[4]。
网果酸模根及根茎为地方草药,其含有很强的抗真菌(白色念珠菌、红色发癣菌)的成分酸模素[5-6],泻下主要药效成分之一蒽醌苷,抗菌消炎、抗肿瘤等作用成分游离蒽醌[7],临床主要用于治疗消化道出血、幽门螺杆菌感染的相关性胃炎、消化性溃疡、十二指肠球部溃疡等[8-10],具有很高的研究和应用价值。目前,网果酸模已有化学成分鉴定、含量测定、指纹图谱等研究[11-12],但基础质量研究未见报道,因此,本实验将从显微鉴别、薄层鉴别(Thin Layer Identification,TLC)、水分、总灰分、酸不溶性灰分、醇溶性浸出物进行研究,为快速、准确的鉴别网果酸模提供科学依据,为完善、建立质量标准和提高临床疗效奠定基础。……
