Problems solved by technology

CBD is a non-addictive component in marijuana, which can hinder the influence of THC on the human nervous system, and has pharmacological activities such as anti-spasmodic, anti-rheumatic arthritis, and anti-anxiety. It has also been reported in the treatment of mental illness, but it is used alone Cannabidiol (CBD) doesn't work well for depression

Embodiment 1

[0033] The flowers, leaves, hemp bran and hemp seeds of "Yunma No. 1", an industrial hemp variety grown in Yunnan, are used as raw materials. Take mature industrial hemp hemp seeds, dry, remove impurities, and crush them for later use; use ethanol to extract the crushed hemp seeds (at 60-85°C, heat and extract twice, each time for 1-3 hours ), the ethanol concentration is 95% to 100% (V / V), and the ratio of solid to liquid is 1:5 to 1:20; the extract is filtered out and concentrated under reduced pressure to obtain the industrial hemp hemp seed extract.

[0034] Take the mixture of industrial hemp flowers, leaves and hemp bran in a mass ratio of 1:3:2, dry, remove impurities, and pulverize to 10-60 mesh; supercritical carbon dioxide extraction: put the above-mentioned pulverized industrial hemp raw materials into supercritical In the carbon dioxide extraction device, the extraction temperature is controlled at 40-50°C, the extraction time is 30-90min, the extraction pressure i...

Embodiment 2

[0037] Repeat Example 1, with the following differences: when extracting industrial hemp hemp seeds with ethanol, extract at room temperature, and extract 2 times for each batch of materials, each for 7 to 10 days. A 1:1:1 mass ratio mixture of flowers, leaves, and hemp bran of industrial hemp is used as a raw material for extracting hemp cannabinoids.

[0038] Get 0.3 part of industrial hemp hemp seed extract, 99.7 parts of industrial hemp cannabinoid, mix well, obtain medicine A of the present invention.

Embodiment 3

[0040] Repeat Example 1, the following difference is arranged: when extracting industrial hemp hemp seed with ethanol, adopt ultrasonic assisted extraction, ultrasonic frequency 30~60kHz, power 100~1000W, extraction time 30~60min, leaching temperature 25~ 50°C. A 3:2:1 mass ratio mixture of flowers, leaves, and hemp bran of industrial hemp is used as the raw material for extracting hemp cannabinoids.

[0041] Get 99.7 parts of industrial hemp hemp seed extract, 0.3 part of industrial hemp cannabinoid, mix well, obtain medicine C of the present invention.

Abstract

The invention discloses a drug for treating depression. The drug is prepared by evenly mixing 0.3-99.7 parts by weight of industrial hemp seed extract and 99.7-0.3 parts by weight of industrial cannabinoid. It is proved through experiments that the drug can significantly shorten the tail suspension immobilization time of mice of a behavioral despair depression model and significantly shorten immobility time of forced swimming, has an obvious anti-depressant effect on a mouse depression model caused by reserpine and can significantly increase the frequency of spontaneous activities of the mice, and the effects are all superior to those of cannabidiol. The drug can be used for preparing drugs for treating various depression symptoms including endogenous depression, reactive depression, masked depression, secondary depression caused by drugs, climacteric or postnatal depression, depression caused by cerebral trauma or cerebral apoplexy, diabetes combined depression and depressive neurosis and used for preparing drugs for treating symptoms such as secondary learning memory decline and anhedonia caused by depression.

Description

technical field [0001] The invention belongs to the field of drugs for treating depression, and in particular relates to a pharmaceutical composition for treating depression prepared from industrial hemp as a main raw material. Background technique [0002] The cultivation of hemp has a long history. In ancient times, hemp was mainly used to make and process ropes, fishing nets, clothing and paper-making raw materials, as well as oil and food. With the development and progress of society, people found that a toxic ingredient (tetrahydrocannabinol) in marijuana can make people addicted to hallucinations. Many countries in Europe and the United States have banned the cultivation of marijuana for a long time. Due to the high economic value of cannabis, by the 1980s, some European countries had researched and bred low-toxic cannabis varieties and promoted their cultivation. In 1990, the European Community took the lead in urgently revising the agricultural policy, abolished the...
