摘 要:目的:利用在线的方式,建立对3个属的新鲜黄芩样品中8种成分(褪黑素、5-羟色胺、吲哚-3-乙酸、金丝桃素、黄芩苷、黄芩素、汉黄芩苷、野黄芩苷)的液相色谱-质谱联用测定方法。方法:植物样品的匀浆与适量填料混合后,被填入相应的样品仓,通过杂质去除,目标物质富集洗脱等步骤,用于成分测定。结果:测定黄芩样品中8种成分,方法的检出限及定量限条件的回收率均大于90%,重复性及稳定性相对标准偏差不大于3.1%。结论:可以用于对黄芩原料中功效成分的评价。Objective: An on-line liquid chromatography-tandem mass spectrometry method was developed to determine 8 components in fresh Scutellaria samples from three germplasm sources. Methods: Mixtures of homogenated tissue samples and appropriate amounts of packing material were packed in sample chamber. After removing matrix impurities and enriching the target analytes, 8 components in fresh Scutellaria samples were determined. Results: The recoveries were greater than 90% at the limits of detection and quantification. Meanwhile, the RSDs of repeatability and stability were less than 3.1%. Conclusion: The method developed can be used for the determination of active components in Scutellaria samples.
