Abstract:
ObjectiveTo analyze the migrating components absorbed into blood of the aqueous extract of Euphorbia helioscopia， and to explore the pharmacodynamic material basis of the aqueous extract of E. helioscopia against chronic obstructive pulmonary disease（COPD）. MethodUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detecte the migrating components absorbed into blood of rats after intragastric administration of aqueous extract of E. helioscopia. An Agilent RRHD SB-C18 column（3 mm×100 mm， 1.8 μm） was used with 0.1% formic acid aqueous solution（A）-acetonitrile（B） as the mobile phase for gradient elution（0-15 min， 5%-30%B； 15-20 min， 30%-50%B； 20-30 min， 50%-95%B； 30-35 min， 95%-5%B）， and the detection wavelength of 190-800 nm， column temperature of 40 ℃， flow rate of 0.3 mL∙min-1 and injection volume of 4 μL. The electrospray ionization（ESI） was used in positive and negative ion modes， and the detection range was m/z 50-1 250. Network pharmacology was used to screen out the key components and the key targets of COPD through the interaction analysis. Metascape database was used to predict the molecular function， biological process， cellular composition and signal pathways mainly involved in the anti-COPD effect of E. helioscopia. Molecular docking technique was used to determine the affinity of key targets with key components. ResultA total of 29 migrating components absorbed into blood of rats were identified after intragastric administration of aqueous extract of E. helioscopia， 9 of which were prototype components and 20 were metabolites. Network pharmacological analysis showed that luteolin， quercetin， apigenin， naringenin and helioscopinolide C were the key components of E. helioscopia against COPD， and vascular endothelial growth factor A（VEGFA）， albumin（ALB）， protein kinase B1（Akt1）， tumor necrosis factor（TNF） and interleukin-6（IL-6） were the key targets. Molecular docking results showed that one diterpene lactone（helioscopinolide C） and three flavonoids（naringenin， luteolin， apigenin） in the migrating components absorbed into blood all had strong binding activity to the key targets of E. helioscopia against COPD. ConclusionNaringenin， helioscopinolide C， luteolin and apigenin may be the main anti-COPD active substances of E. helioscopia.
