ABSTRACT
ObjectiveTo perform a predictive analysis of the quality marker(Q-Marker) for the anticoagulant activity of Kunning granules. MethodThe chemical components of Kunning granules were analyzed by ultra high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry(UHPLC-Q-TOF-MS/MS) on a Waters ACQUITY UPLC HSS T3 column(2.1 mm×100 mm, 1.8 μm) with the mobile phase of acetonitrile(A)-25 mmol∙L-1 ammonium acetate aqueous solution(B) for gradient elution (0-5 min, 5%-22%A; 5-10 min, 22%-30%A; 10-15 min, 30%-95%A; 15-20 min, 95%-5%A; 20-30 min, 5%A), flow rate of 0.2 mL∙min-1, column temperature at 30 ℃, injection volume of 1 μL, electrospray ionization(ESI), positive and negative ion detection modes. Interaction analysis between the targets of chemical components and the targets of abnormal uterine bleeding(AUB) was performed by network pharmacology, and the key components were screened through network topology analysis. The fingerprints of 10 batches of Kunning granules were established by high performance liquid chromatographyHPLC), the anticoagulant activity of the granules was determined by blood coagulation method and fibrinogen plate method, and the spectrum-effective relationship was established. The components co-occurring in the topological analysis and spectrum-effective relationship were selected as Q-Markers, and their anticoagulant activities were verified and confirmed. ResultA total of 475 chemical components were identified from Kunning Granule, of which 22 key components such as salvianolic acid B, paeoniflorin, naringin and neohesperidin, were the potential material basis for the treatment of AUB. The spectrum-effective analysis showed that peaks 7(paeoniflorin), 9(naringin), 10(neohesperidin) and 11(salvianolic acid B) were the optimal principal components, and in vitro activity test showed that these four components could better characterize their anticoagulant activity. ConclusionSalvianolic acid B, paeoniflorin, neohesperidin and naringin may be Q-Markers for the anticoagulant activity of Kunning granules.
