[ 1 ] - Identification of chemical constituents in the extract and rat serum from Ziziphus jujuba Mill. by HPLC-PDA-ESI-MSn

Chinese jujube (Ziziphus jujuba Mill.) has long been widely used for human consumption and medicinal purposes in China. It has been reported to possess several vital biological activities. However, the systematic study on the chemical constituents absorbed into plasma and their metabolites is still insufficient. A high-performance liquid chromatography-photodiode array detector-electrospray ion...

[ 2 ] - Identification and Simultaneous Determination of Twelve Active Components in the Methanol Extract of Traditional Medicine Weichang’an Pill by HPLC-DAD-ESI-MS/MS

Weichang’an (WCA) pill, a traditional Chinese patent medicine consisting of ten Chinese medicinal herbs, has been used to treat irritable bowel syndrome and functional dyspepsia for several decades. In this study, twelve bioactive constituents in the methanol extract of WCA were accurately identified since MS/MS fragmentation behavior of the references and the standards by using HPLC-DAD-ESI-MS...
