In the patent RU 2199312 C1 describes a method of obtaining a dry extract as a medicine. This method involves adding excipients: lactose monohydrate, magnesium stearate, and so on
In the patent RU 2287338 C2 describes a method for tablets of dry extract of St. John's wort, comprising mixing a dry extract with auxiliary substances, seal, screening, processing the condensed extract excipients, including titanium dioxide and talc, followed by pelletizing.
A method of obtaining a dry extract 2192272 (2002) using as adsorbent dry powdered seaweed kelp sugary (Laminaria saccharina) and bladder wrack (Fucus vesiculosus). The disadvantage of this method is the long drying - up to 24 hours.
Known methods for producing dry extract (patent RF №2116797, RF patent №2173557) where the extractant is ethanol and water / ethanol mixture. The disadvantage of this method is the application of organic flammable liquids that require strict security measures and increase the cost of the finished extract.
D is I get dry plant extract were used the following apparatus and materials: electric mill, paper filters, rotary vacuum evaporator mark RM -1, drying Cabinet, scales.
A method includes the following steps:
1. The grinding plant.
2. Extraction of substances from the calculation of 150 grams of vegetable raw materials in 1 liter of water (1:6,6), extracted with water from dry raw material up to 1 litre for 1 hour at the boiling temperature of the solvent.
3. Filtration of the extract.
4. Evaporation of extract obtained at a rotary vacuum evaporator at a temperature of 40-45°C and the atmospheric pressure is 100 mm RT.article.
5. Drying the residue to constant weight in a drying Cabinet at a temperature of 95°C.
The process of evaporation takes place under vacuum at atmospheric pressure of 100 mm RT.article when the boiling temperature of the extract 40°C. the Evaporation in vacuum has certain advantages over evaporation at atmospheric pressure. Evaporation under vacuum gives the possibility to carry out the process at lower temperatures, which is important in the case of concentration of solutions of substances that decompose at elevated temperatures. When the vacuum increases the effective temperature difference between the heating agent and the solution that can reduce the heating surface of the device.
Obtained after evaporation of the product being dried. When drying is the process of removing moisture from the solid. In a drying Cabinet is infrakrasnoe the radiation promotes more intensive removal of moisture.
The result is a resinous substance of a dark brown colour, soluble in water, with a pleasant sweet smell, which is a complex extractive dyes Hypericum perforatum. In appearance resembles a mummy.
The yield of 25.5% by weight of dry plant materials. Developed by the author, the method does not involve the use of additional additives, expensive installations and the use of solvents such as acetone, ethyl and methyl alcohols[3, 4, 5].
The obtained dry extract of St. John's wort is highly soluble in the solvent (water), which was originally extracted.
Finished dry extract enough stored for a long time (5 years or more) at a temperature of +4 -+8°C.
