Characterization and isolation of quinones from Tectona grandis Linn. leaves using innovative hyphenation of TLC-MS interface with LC/MS/MS system

摘要

The successful and innovative hyphenation of TLC-MS interface from CAMAG with Shimadzu LC/MS/MS system has enabled quick, convenient and precise online introduction of bands from TLC plate to MS. Rf values by TLC analysis along with the m/z and fragmentation patterns by LC/MS/MS analysis gives confirm identification and characterization of compounds. Hyphenation of TLC-MS interface with LC/MS/MS system, opens new possibilities into analysis of pharmaceuticals, clinical as well as natural products.
