Embodiment 1
[0049] 1. The formulation and preparation of the quercetin and pinoresinol diglucoside PVP dispersion preparation stage:
[0050] formula:
[0051] Quercetin 20mg
[0052] Pinoresinol Diglucoside 20mg
[0053] PVP-k30 60mg
[0054] Preparation Process:
[0055] Take 20 mg of quercetin and 20 mg of pinoresinol diglucoside in a mixer and mix them evenly, add 60 mg of PVP-k30 to the reaction flask, add an appropriate amount of 95% ethanol, and stir in a water bath at 50°C for 3 hours until the solution is clear, then vacuum The solvent was removed by evaporation, freeze-dried, pulverized into powder, and sieved with 80 meshes to obtain a PVP dispersion of quercetin-pinoresinol diglucoside, which was stored in a desiccator for later use.
