Embodiment 1
[0040] Take 0.5 g of baicalin and 0.25 g of berberine, disperse them with distilled water (6 mL) respectively, put them into dialysis bags (MW, 8000-14000), place them in a beaker filled with 300 mL of distilled water, seal them, and store them at 80 °C Heating under magnetic stirring for 4 h, letting cool to room temperature, centrifuging (4000 rpm, 10 min), separating the supernatant and the precipitate, adding a small amount of distilled water to wash the precipitate repeatedly 2 to 3 times, and drying to obtain "Baicalin-Berberis base" complex.
[0041] The above-mentioned compound was measured as sample 1, and the specific parameters are shown in Table 1.
Embodiment 2
[0043] Take 0.5 g of baicalin and 0.5 g of berberine, disperse them with distilled water (6 mL) respectively, put them into dialysis bags (MW, 8000~14000), place them in a beaker filled with 300 mL of distilled water, seal them, and store them at 80 °C Heating under magnetic stirring for 4 h, letting cool to room temperature, centrifuging (4000 rpm, 10 min), separating the supernatant and the precipitate, adding a small amount of distilled water to wash the precipitate repeatedly 2 to 3 times, and drying to obtain "Baicalin-Berberis base" complex.
[0044] The above-mentioned compound was measured as sample 2, and the specific parameters are shown in Table 1.
Embodiment 3
[0046] Take 0.5 g of baicalin and 1.0 g of berberine, disperse them with distilled water (6 mL) respectively, put them into dialysis bags (MW, 8000~14000), place them in a beaker filled with 300 mL of distilled water, seal them, and store them at 80 °C Heating under magnetic stirring for 4 h, letting cool to room temperature, centrifuging (4000 rpm, 10 min), separating the supernatant and the precipitate, adding a small amount of distilled water to wash the precipitate repeatedly 2 to 3 times, and drying to obtain "Baicalin-Berberis base" complex.
[0047] The above-mentioned compound was measured as sample 3, and the specific parameters are shown in Table 1.
