摘要(Abstract):

目的:优选大孔吸附树脂纯化铁棒锤总生物碱的最佳条件,比较不同产地铁棒锤中总生物碱与乌头碱的含量,为进一步研究铁棒锤质量提供依据。方法:采用正交设计优选大孔吸附树脂对铁棒锤总生物碱的最佳纯化条件,以滴定法测定总生物碱的含量。采用最佳工艺条件对4个不同产地铁棒锤的总生物碱进行纯化,并用HPLC测定乌头碱的含量。结果:不同工艺条件对总生物碱的纯化有不同影响。最佳纯化条件为树脂型号HPD-722,80%乙醇,乙醇洗脱量80mL·min-1。HPLC测得青海、马衔山、宁夏、永登4个不同产地铁棒锤中乌头碱质量分数分别为0.4935,0.8835,1.5278,1.6644mg·g-1。结论:该文的最佳工艺条件可用于总生物碱和乌头类生物碱的纯化。不同产地铁棒锤中乌头碱含量以甘肃永登栽培最高。
Objective:To optimize the conditions of purifying the total alkaloids in Aconitum szechenyianum with macroporous adsorption resin,and compare the content of total alkaloids and aconitine in A.szechenyianum from different producing areas,in order to provide basis for further studies.Method:The orthogonal experiment method was adopted for optimizing the conditions of purifying the total alkaloids in A.szechenyianum with macroporous adsorption resin.The content of total alkaloids and aconitine were determined by using the titration method.The total alkaloids in A.szechenyianum from different producing areas were purified under optimum processing conditions.Aconitine was determined by HPLC.Result:Different processing conditions showed different influences on the purification of total alkaloids.The optimum conditions were resin type HPD-722,ethanol concentration of 80%,and ethanol elution volume of 80 mL·min-1.The contents of aconitine in A.szechenyianum from different producing areas——Qinghai,Maxianshan,Ningxia and Yongdeng were 0.493 5,0.883 5,1.527 8,1.664 4 mg·g-1,respectively.Conclusion:The optimum processing conditions used in this essay could be used for purifying the total alkaloids and aconitine.A.szechenyianum from Yongdeng and Gansu contains the highest content of aconitine.
