Abstract
The invention discloses a Chinese herbal composition and extract used for treating depression and a preparation method and an application thereof. The Chinese herbal composition is composed of bupleurum, Chinese angelica, fried white atractylodes rhizome, honey-fried licorice root, mint and dried ginger, thus a formula is simpler. The preparation method of the Chinese herbal composition comprises the steps of weighing the Chinese herbal medicines in proportion, smashing the Chinese herbal medicines, placing the smashed Chinese herbal medicines into a CO2 extraction kettle, controlling parameters such as pressure, temperature, CO2 flow and extraction time and obtaining the extract. Pharmacodynamic test results show that the extract can obviously reduce dead time in a mouse forced swinging test and a mouse tail suspending test, which proves that the extract disclosed by the invention has obvious anti-depression effect, anti-depression activity reaches up to or is higher than those of anti-depression western medicines which are frequently used in clinical application and the traditional anti-depression Chinese herbal medicine compound Xiaoyao powder. And the extract is prepared by adopting an advanced and non-toxic supercritical CO2 extraction process without pollution or solvent residue, thus safety is better, and the extract disclosed by the invention is an ideal anti-depression medicine.
Description
technical field [0001] The invention relates to a traditional Chinese medicine composition, in particular to a traditional Chinese medicine composition for treating depression, an extract and a preparation method and application thereof. Background technique [0002] Depression is a common mental illness, characterized by high incidence, high recurrence rate, and high disability rate. The incidence rate in my country is 2.5%, and the number of patients exceeds 30 million. Severe cases have suicidal tendencies. However, the current drugs for the treatment of depression are not ideal, mainly based on chemical drug therapy, such as tricyclics (imipramine, amitriptyline, etc.), monoamine oxidase inhibitors (phenelzine, moclobemide, etc.) , selective 5-HT reuptake inhibitors (fluoxetine, paroxetine, sertraline, venlafaxine, etc.), but these chemical drugs have problems such as narrow therapeutic spectrum, poor tolerance, large toxic and side effects, and high price .
