Embodiment 1
[0070] (1) Instruments and reagents: Waters ALLIANCE high performance liquid chromatography (E2695 quaternary pump, autosampler, column thermostat, 2998 diode array detector, vacuum degasser, Empower3 Chromatography Workstation); BP211D electronic balance from Sedlis, Germany; Luna C from Phiromens, USA 18(2) Chromatography column (4.6mm×250mm, 5μm). Methanol is chromatographically pure, and other reagents are analytically pure.
[0071] (2) Test solution: Take propolis medicinal material powder, accurately weigh about 1.0000g, put it in a Soxhlet extractor, extract it with 100mL acetone Soxhlet until it is colorless, evaporate the extract to dryness in a water bath, dissolve the residue in methanol, and place in a Soxhlet extractor. In a 100mL measuring bottle, dilute to the 100mL mark with methanol.
[0072] (3) The mobile phase is: A: methanol, B: phosphoric acid solution with a concentration of 0.4% by volume; gradient elution method: 0min→10min→20min→30min→38min→56min→6...

[0093] (1) Instruments and reagents: Waters ALLIANCE high performance liquid chromatography (E2695 quaternary pump, autosampler, column thermostat, 2998 diode array detector, vacuum degasser, Empower3 Chromatography Workstation); BP211D electronic balance from Sedlis, Germany; Luna C from Phiromens, USA 18(2) Chromatography column (4.6mm×250mm, 5μm). Methanol is chromatographically pure, and other reagents are analytically pure.
[0094] (2) Test solution: Take propolis medicinal material powder, accurately weigh about 1.0000g, put it in a Soxhlet extractor, extract it with 100mL acetone Soxhlet until it is colorless, evaporate the extract to dryness in a water bath, dissolve the residue in methanol, and place in a Soxhlet extractor. In a 100mL volumetric flask, dilute methanol to the mark.
[0095] (3) The mobile phase is: A: methanol, B: phosphoric acid solution with a concentration of 0.4% by volume; gradient elution method: 0min→10min→20min→30min→38min→56min→67min→72min→...

[0117] (1) Instruments and reagents: Waters ALLIANCE high performance liquid chromatography (E2695 quaternary pump, autosampler, column thermostat, 2998 diode array detector, vacuum degasser, Empower3 Chromatography Workstation); BP211D electronic balance from Sedlis, Germany; Luna C from Phiromens, USA 18(2) Chromatography column (4.6mm×250mm, 5μm). Methanol is chromatographically pure, and other reagents are analytically pure.
[0118] (2) Test solution: Take propolis medicinal material powder, accurately weigh about 1.0000g, put it in a Soxhlet extractor, extract it with 100mL acetone Soxhlet until it is colorless, evaporate the extract to dryness in a water bath, dissolve the residue in methanol, and place in a Soxhlet extractor. In a 100mL volumetric flask, dilute methanol to the mark.
[0119] (3) The mobile phase is: A: methanol, B: phosphoric acid solution with a concentration of 0.4% by volume; gradient elution method: 0min→10min→20min→30min→38min→56min→67min→72min→...
