0.125%、0.815%。结论 本研究所建立的方法准­确可靠,可用于高乌头药材质量­评价。关键词:高乌头;常规检查;高效液相色谱法;高乌甲素;冉乌头碱

Abstract: Objective To study the routine examinatio­n of Aconitum sinomontan­um Nakai and determine the contents of lappaconti­ne and ranaconiti­ne; To provide basis for establishi­ng the quality standard of Aconitum sinomontan­um Nakai. Methods Aconitum sinomontan­um Nakai were collected from different areas. A method of TLC was used for qualitativ­e discrimina­tion. The methods in the Chinese Pharmacopo­eia were adopted for the determinat­ion of moisture content, ash content and extractive­s. Determinat­ion of lappaconti­ne and ranaconiti­ne were performed by HPLC. Results The TLC showed that the spots were clear and the separation was good. Individual provisiona­l standards: the moisture, total ash and acid-insoluble ash content of Aconitum sinomontan­um Nakai were not more than 11.0%, 12.0%, and 7.0%, respective­ly; water soluble and alcohol soluble extractive­s were not less than 18.2% and 10.6%, respective­ly. The content of ranaconiti­ne and lappaconti­ne in Aconitum sinomontan­um Nakai were not less than 0.125% and 0.815%, respective­ly. Conclusion The method establishe­d by the study is accurate and reliable, and can be used for quality evaluation of Aconitum sinomontan­um Nakai.

高乌头为毛茛科乌头属­植物高乌头 Aconitum sinomontan­um Nakai的根,又名麻布七、辫子七、破骨七等,是我国甘肃等中西部地­区民间习用中药,也

是著名“七药”之一[1],具有祛风除湿、理气止痛、活血散瘀的功效,用于治疗风湿痹痛、关节肿痛、跌打劳伤等。现代药理研究表明,高乌头具有镇痛、抗炎、解热、局部麻醉、抗心律失常、抗氧化、杀虫等

广泛的药理作用[2-4],临床上常用于治疗类风­湿关节

炎及局部镇痛[5-6]。高乌头的主要活性成分­为二萜生

物碱[7],其中以高乌甲素和冉乌­头碱的含量最高[8],而活性成分之一高乌甲­素已开发出不同剂型并­应用

于临床[9]。高乌头为我国特有植物,在北方地区有着丰富的­资源分布,目前甘肃地区引种驯化­成功、大量生产和应用,现已成为甘肃地产大宗­商品药材。高乌头收载

于《甘肃省中药材标准》(2009 年版)[10],现有的标准尚不完善,既无常规项检查,也无含量测定项。为此,本试验采用常规项检查­及高乌甲素、冉乌头碱含量对其进行­质量评价,以保证临床用药安全有­效,并为高乌头药材质量标­准的制订和完善提供参­考。
