Problems solved by technology

In some patents (on March 15th, 2000, publication number CN 1247071A), its method is simple and easy, and the content of extracting hypericin is not high; in some patents (on July 18th, 2001, publication No. CN 1304397A), the extracted content is higher, but the required equipment is more complicated
At the same time, hypericin still has some side effects, including serotonin syndrome, photosensitivity, gastrointestinal irritation, fatigue, insomnia, and allergic reactions. At present, there is no good solution

Embodiment 1

[0010] The preparation of hypericin:

[0011] (1) According to the above-mentioned method, take 1000g of Hypericum perforatum, add KOH with a concentration of 1% and NaHCO with 8% 3 solution in 1000ml, soak and boil for 8 minutes, filter through gauze, and obtain the filtrate (a);

[0012] (2) The resulting residue was treated with 1.5% NaHCO 3 Solution 500ml, boiled for 8 minutes and filtered to obtain filtrate (b);

[0013] (3) combining the filtrates (a), (b) and drying to obtain the extract;

[0014] (4) The extract is dissolved in 500ml of propanol, the two are mixed and concentrated and filtered;

[0015] (5) Add high-concentration ethanol to the filtrate to make the alcohol content reach 65%, refrigerate, filter to obtain the alcohol liquid, reclaim the ethanol, then concentrate, refrigerate, and filter to obtain the filtrate; adjust the ethanol concentration to 80% in the filtrate, and then refrigerate 1. After filtering to obtain the filtrate, reclaim the ethanol ...

Embodiment 2

[0025] Tablets containing the extract of Example 1:

[0026] (1) 150 g of the extract obtained from Hypericum perforatum in Example 1 was pulverized.

[0027] (2) According to the national standard, the pulverized product is mixed with 50 g of taurine, 2 g of zinc, 10 g of vitamin C, 2.5 g of vitamin E, sweetener and other ingredients.

[0028] (3) Adding a pharmaceutically acceptable carrier such as a wetting agent to the mixture to make it into a soft material, and then drying it under vacuum.

[0029] (4) Make the dried material into granules with appropriate thickness and elasticity and dry.

[0030] (5) After adding a wetting agent to the granules, mix them evenly, and press them into tablets with a special tablet press machine, each tablet weighing 250 mg.

Abstract

The method for extracting hypericin from hypericum perforatum includes the following steps: soaking plant hypericum perforatun in KOH and NaHCO3 solution with a specific concentration, boiling, filtering and drying to obtain its extract, dissolving said extract in propyl alcohol, filtering solute, and using water-alcohol process to refine the extract so as to obtain the invented product. It is used as main component, and matched with other component, and can be made into the hypericin medicine composite or other different dosage forms for curing depression.

Description

Technical field: [0001] The invention relates to a method for extracting hypericin from Hypericum perforatum and a series of medicines for treating depression prepared by using hypericin as a main component.
