目的:比较炮制对乌头各部位中生物碱类成分的影响与其自身含量差异。方法:以滴定法测定总生物碱的含量,高效液相色谱法测定三种双酯型生物碱和三种单酯型生物碱的含量。结果:生川乌、生附子中总生物碱的平均含量分别为1.09%,1.33%。生川乌、生附子中三种双酯型生物碱含量总和分别为0.74%,0.96%;生川乌、生附子中三种单酯型生物碱的含量分别为0.032%,0.001%。生川乌炮制后的总生物碱含量为0.55%,三种单酯型生物碱含量为0.125%;附子的两个炮制品,白附片和黑顺片总生物碱含量降低,其含量分别为0.07%和0.05%,白附片、黑顺片中三种单酯型生物碱略有升高,其含量均为0.012%。炮制品中三种双酯型生物碱均未检测到。三种炮制品中总生物碱含量比为,制川乌:白附片:黑顺片=11∶1.4∶1,三种单酯型生物碱含量比为,制川乌:白附片:黑顺片=10.5∶1∶1。结论:乌头不同部位中生物碱的含量差异较小,炮制后生物碱类成分含量变化较大。炮制对乌头不同部位中生物碱类成分的影响要大于其自身含量差异。
