Embodiment 1

[0061] Weigh 10g of cannabidiol crystals (purity 99%), melt them with 100g of PEG4000 and 50g of poloxamer 188 in a water bath at 70°C to become a homogeneous liquid, and place it directly in a -19°C refrigerator for 24 hours to obtain Solid Dispersion 1.

Embodiment 2

[0067] Weigh 20g of full-spectrum oil (CBD content 80%), 120g of PVP K30, 10g of Tween 80 and dissolve them in 200mL of absolute ethanol, dissolve evenly by ultrasonication, react at 60°C for 5h, and then dry the mixed solution under reduced pressure to obtain Cannabidiol solid dispersion 2, the prepared solid dispersion is ground into a powder product.

Embodiment 3

[0069] Weigh 20g of full-spectrum oil (CBD content 56%, CBDV content 40%) and dissolve it in 20mL of absolute ethanol, mix 120g of PEG4000 and PEG6000 at a ratio of 1:1, and melt 10g of Tween 80 together to form a homogeneous liquid at 80°C. Add the ethanol solution of cannabidiol into the molten liquid, mix evenly, evaporate the ethanol in a water bath at 80°C, then place the mixed solution in an ice-water bath, cool and solidify to obtain the solid dispersion 3.

Abstract

The invention provides a preparation method of a cannabidiol solid dispersion, the solid dispersion prepared by the method and an application of the solid dispersion, the cannabidiol solid dispersion is obtained by forming a molecular-level dispersion in a water-soluble solid carrier by using cannabidiol under the condition of adding an emulsifier, and then cooling or drying. The obtained solid dispersion can solve the problem that cannabidiol is insoluble in water, and the solubility and bioavailability of cannabidiol are improved. The cannabidiol solid dispersion is simple in preparation process and convenient for industrial production; and the application field of cannabidiol is expanded, and the obtained cannabidiol solid dispersion can also be used for foods, beverages and daily chemical products, and can also be combined with a steady-state technology as required during application.

Description

technical field [0001] The invention belongs to the field of preparation preparation and application, and relates to a preparation method of a cannabidiol solid dispersion with improved solubility, the cannabidiol solid dispersion prepared by the method and its application. Background technique [0002] Cannabidiol is a natural active ingredient from the stems, leaves, and seeds of the annual herb Cannabis genus Cannabis, which has a variety of pharmacological activities, and has anti-tumor effects, neuroprotective effects, metabolic and immune regulation effects, and cardiovascular protection. Anti-inflammatory and antioxidant effects, hepatoprotective and antibacterial effects. The numerous pharmacological effects of cannabidiol can be used in many aspects such as medicine, food, skin care products, health care products and pet products to exert its different effects. However, since cannabidiol is a fat-soluble substance, it is extremely difficult to dissolve in water. It...
