摘要: 本文主要运用超高效液相串联四级杆飞行时间质谱联用技术(UPLC/Q-TOF MS)对三七中皂苷类成分进行快速分离和鉴定。以超高效液相为分离手段,飞行时间质谱仪为鉴定方法,水饱和正丁醇为提取溶剂,以0.05%甲酸水(A)-0.05%甲酸乙腈(B)为流动相进行梯度洗脱,采用ESI负离子模式进行数据采集。根据实验结果,并结合相关参考文献,二级质谱裂解数据以及元素组成,分离、鉴定出17种皂苷类成分,并发现三七中含有姜糖酯B成分。实验结果表明经过超高效液相的分离,以及Q-TOF MS的二级负离子信息的鉴定,为分析三七中皂苷类成分提供了一种快速、简便、可靠的方法。

Abstract: In this study,ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF MS) technique was used to rapidly separate and identify saponin components in Panax notoginseng. Water saturated n-butyl alcohol was used as extraction solvent.Chromatographic separation was carried out on a BEH C18 column with gradient elution of 0.05% formic acid in water (A) and 0.05% formic acid in acetonitrile (B).The Q-TOF MS analysis was applied in ESI negative mode.According to the experimental result,17 saponins were separated and tentatively identified by UPLC/Q-TOF MS based on reference literatures,MS/MS fragment ions information and elemental composition in Masslynx 4.1.Among these 17 compounds,including 8 ginsenosides and 9 notoginsenosides,gingerglycolipid B was detected in P.notoginseng. The developed UPLC-Q-TOF MS method was simple,rapid and reliable for the identification of saponin component in P.notoginseng.
