Two new phenylpropanoid glycosides lagotiside C and D, along with 11 known compounds were isolated from the whole plant of Lagotis brachystachya Maxim. The structures of lagotiside C and D was elucidated on the basis of spectroscopic data analysis. Moreover, all isolated components were
The chemical constituents of Lagotis brevituba were rapidly determined and analyzed by using ultra performance liquid chromatography tandem quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS/MS) method, providing material basis for the clinical application of L. brevituba. The separation was
OBJECTIVE
Sustained pulmonary vasoconstriction as experienced at high altitude can lead to pulmonary hypertension (PH). The main purpose of this study is to investigate the vasorelaxant effect of echinacoside (ECH), a phenylethanoid glycoside from the Tibetan herb Lagotis brevituba Maxim and
