Problems solved by technology

[0004] Pure cannabidiol is solid and difficult to dissolve in water. Direct use will reduce its bioavailability, which is not conducive to human absorption
This undesirable characteristic has brought obstacles to the use of cannabidiol
Hemp oil has certain health care functions, but its medicinal value is not outstanding, which limits its use

Abstract

The invention discloses a preparation method and application of hemp essential oil containing hemp bisphenol and belongs to the technical field of processing of industrial hemp. The preparation methodcomprises the following steps: 1, preparation of hemp bisphenol: drying, smashing and drying fresh industrial hemp flowers and leaves, carrying out CO2 supercritical extraction to obtain a crude extract, and carrying out silica column chromatography separation and purification, concentration, crystallization and drying to obtain 99% or above of hemp bisphenol (CBD); 2, preparation of hemp oil: drying, smashing and drying fresh hempseeds, and carrying out CO2 supercritical extraction to obtain hemp oil; and 3, preparation of the hemp essential oil containing hemp bisphenol: mixing the hemp bisphenol with the hemp oil according to a certain proportion, and carrying out stirring to sufficiently dissolve a solid so as to obtain the hemp essential oil containing hemp bisphenol. The hemp essential oil obtained by using the preparation method can be applied to the addition of daily chemical products, drugs, health products, food and beverages.

Description

technical field [0001] The invention belongs to the technical field of industrial hemp processing, and in particular relates to a preparation method and application of hemp essential oil containing cannabidiol. Background technique [0002] Cannabidiol (CBD) is a natural active ingredient from the stems, leaves and seeds of the annual herb Cannabis sativa Linn. Cannabis sativa Linn. It has anti-inflammatory, bactericidal, analgesic, anti-anxiety, anti-psychotic, anti-oxidative, improving learning and memory, neuroprotection and reducing intestinal peristalsis, etc. It can be used to treat multiple arteriosclerosis and Parkinson's disease, prevent myocardial infarction, and block mammary glands It can also be used to treat spasticity and movement disorders, cancer pain, neuralgia, migraine, and epilepsy in patients with glaucoma, paraplegia, and multiple sclerosis. Cannabidiol is used in daily chemicals, which can resist oxidation, resist free radicals, moisturize; anti-infl...
