specific Embodiment approach 1

[0041] Specific embodiment one: present embodiment a kind of extraction method that improves the content of cannabidiol in hemp essential oil, it is to carry out according to the following steps:

[0042] 1. Pretreatment:

[0043] Collect fresh hemp flowers and leaves as raw materials, put the raw materials in the freezer, freeze for 0 days to 60 days, take them out after freezing and let them stand naturally to warm up to room temperature, and then place them at a temperature of 120 ° C to 160 ° C to keep warm 0min to 8min, and finally let it stand naturally to room temperature to obtain the pretreated raw material;

[0044] Second, broken:

[0045] 1. Mix the pretreated raw material with distilled water and place it in a cooking machine; the mass ratio of the pretreated raw material to distilled water is 1:(1~5);

[0046] ②. Under the condition that the power of the cooking machine is 1000 watts to 1500 watts and the speed is 15000 rpm to 40000 rpm, stir and crush for 2 mi...

specific Embodiment approach 2

[0061] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the surfactant described in step three is one or more of anionic surfactants, cationic surfactants and nonionic surfactants mixture. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0062] Specific embodiment three: this embodiment is different from one of specific embodiment one or two: the surfactant described in step 3 is sodium lauryl sulfate, polyoxyethylene sorbitan monostearate and A mixture of lauroyl sarcosine, or a mixture of sodium lauryl sulfate, sodium dodecylbenzenesulfonate and polyoxyethylene sorbitan monostearate. Others are the same as in the first or second embodiment.

Abstract

The invention discloses an extraction method for increasing the content of cannabidiol in China-hemp essential oil, and belongs to the technical field of essential oil preparation. The invention aims to solve the problem of low CBD content in China-hemp essential oil in the existing extraction method of China-hemp essential oil. The method comprises the steps of 1, pretreating; 2, smashing; 3, preparing a distillate; and 4, separating. The method is used for increasing the content of cannabidiol in the China-hemp essential oil.

Description

technical field [0001] The invention belongs to the technical field of essential oil preparation. Background technique [0002] Hemp, also known as industrial hemp, is a type of hemp with no drug use value. Its tetrahydrocannabinol (THC) content is less than 0.3%, and it is rich in various biologically active components such as terpenes, phenols, and flavonoids. Hemp essential oil is secreted by glandular trichomes distributed on the epidermis of inflorescences and leaves, and consists of monoterpenes, bitter sesquiterpenes and cannabinoids. Its cannabinoid components include cannabidiol (CBD), tetrahydrocannabinol (THC), cannabichromene, etc. Among them, the most valuable component is CBD, and the price of high-purity CBD in the international market is about 4000~ 8000 USD / kg. As a non-psychoactive compound, CBD can counteract the negative effects of THC, and also has antioxidant, neuroprotective, immunomodulatory and insecticidal activities. [0003] Hemp essential oil ...
