  摘要:目的 對高烏頭藥材進(jìn)行常規(guī)項(xiàng)檢查并測定高烏甲素、冉烏頭堿含量,為建立高烏頭藥材質(zhì)量標(biāo)準(zhǔn)提供參考。方法 采集不同產(chǎn)地高烏頭藥材,采用薄層色譜法進(jìn)行定性鑒別,按藥典水分測定法(烘干法)、灰分測定法、浸出物測定法測定水分、灰分和浸出物,采用HPLC測定高烏甲素和冉烏頭堿含量。結(jié)果 薄層色譜斑點(diǎn)清晰,分離度好;暫定高烏頭藥材中水分、總灰分及酸不溶性灰分分別不得過11.0%、12.0%、7.0%,水溶性浸出物和醇溶性浸出物分別不少于18.2%、10.6%;高烏頭藥材中冉烏頭堿和高烏甲素含量分別不少于0.125%、0.815%。結(jié)論 本研究所建立的方法準(zhǔn)確可靠,可用于高烏頭藥材質(zhì)量評價。

  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.
