ABSTRACT
Chemical constituents in extract of Scrophulariae Radix and their metabolites in rat plasma after oral administration were identified by HPLC-LTQ-Orbitrap. Samples were separated by a Venusil MP C₁₈ column using a binary gradient elution. The information on the total ion chromatogram, the extraction chromatogram and the mass spectrogram in a negative mode were synthetically analyzed by comparing the retention time, MS and MS/MS spectra with literature data and some of reference standards to conduct a qualitative study on constituents of Radix Scrophulariae extract in vivo and in vitro. Totally 37 compounds from Scrophularia ningpoensis extract were detected including 12 iridoid glycosides, 20 phenylpropanoids and 5 unknown compounds. In vivo, harpagide, harpagoside and angoroside C were confirmed to enter into the blood in prototype forms. Besides, another 2 prototype compounds and 2 metabolites were detected in rat plasma after oral administration of S. ningpoensis extract. The results are beneficial for the determination of bioactive substances of S. ningpoensis and significant for further studies on S. ningpoensis.
