摘要
采用UHPLC-Q-Orbitrap-HRMS技术建立司卡摩尼亚脂中化学成分的快速分析方法。采用Full MS/dd-MS扫描模式采集质谱数据,根据获得的精确分子量、二级碎片信息,归纳总结裂解途径,结合文献报道和Compound Discover数据库预测,从司卡摩尼亚脂甲醇提取物中共鉴定出92个化合物,包括72个醚溶性树脂糖苷和树脂酸类成分、12个羟基肉桂酰基奎宁酸类和8个醚不溶性树脂酸类。其中,8个醚不溶性树脂酸类(化合物10、12、13、16、17、18、19、20)和2个三聚体奎宁酸类(化合物14、15)为本药材中首次发现的化合物。研究结果为今后司卡摩尼亚脂药材及其产品质量标准的建立提供科学依据。
The rapid analysis method for the chemical compositions in scammony methanol extract was established by UHPLC-Q-Orbitrap HRMS.The mass data were acquired by Full MS/dd-MS scan mode,and data analysis were performed by the information of accuracy molecular weight,fragment ion,summarized fragmentation pathway,combined with previous references and Compound Discovery(CD)software.Totally,92 compounds were identified from scammony methanol extract,including 72 resin glycosides,12 hydroxyl cinnamoyl quinic acids,eight ether insoluble resin glycoside acids.Among them,eight ether insoluble resin glycoside acids(compounds 10,12,13,16,17,18,19 and 20)and two tricaffeoylquinic acids(compounds 14 and 15)were detected first in scammony.The results provide a scientific basis for the future research on the improvement of the quality standard for scammony and its relative products.
