【摘要】:采用直噴離子化質(zhì)譜技術(shù),通過對關(guān)木通的敞開式質(zhì)譜輪廓分析,對關(guān)木通和其它兩種木通(木通、川木通)進行了快速鑒別,建立了關(guān)木通中木蘭花堿的快速測定方法。結(jié)果表明,可以利用標志性成分木蘭花堿對馬兜鈴科關(guān)木通進行鑒別;同時,在正離子模式下,以荷葉堿為內(nèi)標,木蘭花堿與內(nèi)標的信號強度比與木蘭花堿標準溶液的濃度,在0.50~20.00 mg/L范圍內(nèi)線性關(guān)系良好,相關(guān)系數(shù)為0.9989,檢出限為0.1 mg/L。本方法簡單、快速、無需樣品前處理,可用于有毒藥材關(guān)木通的直接、原位、快速分析和鑒定。本研究結(jié)果對木通中藥材的質(zhì)量控制具有重要參考價值。
[Abstract]:By means of direct spray ionization mass spectrometry and by analyzing the profile of open mass spectrometry, the rapid identification of Akebia mandshurica and two other kinds of Akebia (Akebia mandshurica) was carried out, and a rapid method for the determination of magnolia alkaloids in Akebia mandshurica was established.The results showed that the signature component of Magnoliae could be used to identify Aristolochia Aristolochia, and at the same time, under the positive ion mode, with lotus leaf alkali as the internal standard, the signal intensity ratio of Magnolia alkaloid to internal standard solution and the concentration of the standard solution of Magnolia alkaloid could be obtained.The correlation coefficient was 0.9989 and the detection limit was 0.1 mg 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) 路L ~ (-1).The method is simple, rapid, and can be used for direct, in situ, rapid analysis and identification of the toxic medicinal herbs Astragalus mandshurica without sample pretreatment.The results of this study have important reference value for quality control of Akebia chinensis.
