试图在根值 Scrophulariae (Scrophularia ningpoensis ) 分析主要成分。方法根值 Scrophulariae 被结合的 HPLC 分析 electrospray 电离四极 time-of-flight 双人脚踏车团 spectrometry (ESI-Q-TOF MS/MS ) 。混合物被 HPLC 用 C18 列和 acetonitrile 和 0.1 %(V/V ) 的坡度 elution 分开醋性酸水。否定离子模式被采用。36 全部的结果 A 加重,包括十四 iridoid glycosides,十九 phenylpropanoid glycosides,和三器官的酸,基于先锋和产品离子的精确集体测量从根值 Scrophulariae 被识别。21 成分被参考标准或以前的出版物把他们的保留时间(tR ) 和 ESI-MS/MS 数据与那些作比较识别,当十五混合物尝试性地根据他们负担得起足够的结构的信息的 Q-TOF MS/MS 数据被识别或推出时。这学习,这被相信的结论为在根值 Scrophulariae 的成分的鉴定是有用的,以及联系植物和复杂药方。
AIM: To analyze the major constituents in Radix Scrophulariae (Scrophularia ningpoensis). METHOD: Radix Scrophulariae was analyzed by HPLC coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (ESI-Q-TOF MS/MS). Compounds were separated by HPLC using a C18 column and gradient elution of acetonitrile and 0.1% (V/V) acetic acid-water. Negative ion mode was employed. RESULTS: A total of thirty-six compounds, including fourteen iridoid glycosides, nineteen phenylpropanoid glycosides, and three organic acids, were identified from Radix Scrophulariae based on the accurate mass measurement of precursor and product ions. Twenty-one of the constituents were identified by comparing their retention times (tR) and ESI-MS/MS data with those of reference standards and/or previous publications, while another fifteen compounds were tentatively identified or deduced according to their Q-TOF MS/MS data which afforded sufficient structural information. CONCLUSION: It is believed that this study is useful for the identification of constituents in Radix Scrophulariae, as well as related plants and complex prescriptions.
