[Abstract]
Objective The differences of ethanol and water extracts from Mangguoye (Mangiferae Indicae Folium, MIF) in eliminating stagnation effects were explored, then HPLC fingerprints of MIF ethanol and water extracts of different varieties were established, and network pharmacology and multi-component quantification were used to investigate the differential components of eliminating stagnation in two MIF extracts. Methods Ethanol and water extracts from MIF of different varieties were prepared; the effects of “promoting qi and eliminating stagnation” of two MIF extracts were explored by suckling SD rats. Then a Merck STAR RP-18e (250 mm×4.6 mm, 5 μm) column was used with acetonitrile-0.1% phosphoric acid aqueous solution as the mobile phase for gradient elution, with column temperature of 30 ℃, volume flow rate of 0.8 mL/min, detection wavelength of 216 nm, and the fingerprint of eight MIF water extracts and eight MIF ethanol extracts was drawn to screen the common peaks. The hierarchical cluster analysis (HCA), principal component analysis (PCA) and network pharmacology methods were used to evaluate the differential components of eliminating stagnation in MIF under different treatment methods. And the content of four measurable effective components was determined. Results Two MIF extracts all had the ffects of eliminating stagnation. MIF ethanol extract was beneficial for the increase of suckling SD rats weight and gastric emptying rate, while its water extract could improve the small intestine propulsion rate and gastric emptying rate. Fourteen shared peaks were identified from the MIF fingerprint profile, with similarities between 0.646 and 0.984 for each batch. The results of HCA and PCA showed that MIF extracts could be clustered analysis. Fourteen compounds were predicted and analyzed in MIF with eliminating stagnation effects by network pharmacology, and four compounds were identified as common peaks in the fingerprint by comparison with the reference substances, namely myricetin 3-O-β-D-galactopyranoside, luteolin-7-O-glucuronide, quercitrin and quercetin. The contents of myricetin 3-O-β-D-galactopyranoside, luteolin-7-O-glucuronide, quercitrin and quercetin in MIF were 0.081%—0.297%, 0.254%—3.104%, 0.005%—0.056%, 0.029%—0.314%, respectively. Conclusion MIF extracts have eliminating stagnation effect, HPLC fingerprint combined with network pharmacology and chemometrics can be used to assess and screen the differences of eliminating stagnation components in MIF, which provides provide a basis for its quality control.
