The method of obtaining essential oils from the bark of coniferous plants

 

The invention relates to methods for extracting coniferous essential oils from plant materials and can be used in forestry, pharmaceutical, chemical, medical and other industries. Carry out the distillation of essential oils with water vapor at a temperature of 90-100oC and a pressure of 0.07 to 0.15 MPa for 8-10 hours as plant materials used crushed to the size of 1-2 cm bark of spruce, fir Belokolos, Dahurian larch, Korean pine cedar - waste of trees from cuttings of the main and intermediate areas, as well as wood processing. The invention allows to increase the content of chamazulene in the product. 1 C.p. f-crystals, 1 tab., 1 Il.

The invention relates to methods for extracting pine oils from plant materials and can be used in forestry, pharmaceutical, chemical, medical and other industries.

A known method for the production of pine oil [1].

Closest to the claimed invention to the technical essence is a method of extracting essential oils from plant material by steam distillation [2].

The disadvantage of this method compared to the claimed are saravanou system 5 - and 7-membered cycles. The simplest representative - azulene.

In nature many azulene found in essential oils, for example, chamazulene (1,4-dimethyl-7-atieswin). Chamazulene intensely colored blue and gives pine essential oil bluish tint.

The aim of the invention is the search for sources of plant raw materials containing azulene and getting coniferous essential oils with their high content, in particular chamazulene; recycling of wood waste, expanding the raw material base of biologically active substances.

Essential oils containing azulene may be used as a raw substance (Foundation) to create medicines.

Now produce the drug "Romashin" made in Romania has antiseptic and deodorizing properties. It is used for gastritis, colitis, flatulence, inflammatory diseases of the mucous membranes and skin [3].

Essential oils that contain azulene, such as oil of yarrow, chamomile, antiseptic, anti-inflammatory, antispasmodic, sedative, analgesic, antiulcer and wound healing actions [4].

Identify new sources of content Aslanov, increasing their output is important is used as a raw material substance (base) to create medicines. They can be used as a total natural products in medicine, perfumery, cosmetics and aromatherapy.

The goal is to achieve that: 1) the distillation of essential oils with steam is carried out at a temperature of 90-100oWith the pressure of 0.07-0.15 MPa for 8-10 hours; 2) as a plant raw material use shredded bark waste of trees from cuttings of the main and intermediate use and processing of wood fir Belokolos, spruce, spruce, Korean, Dahurian larch, Korean pine cedar.

An example of performing the method.

Bark waste of trees from cuttings of the main and intermediate use or processing of wood, chopped to the size of 1-2 cm, loaded into a boiling VAT installation periodic operation, with a capacity of 1-2 m3and passed through her water vapor from the boiler of a steam generator (type e-coat-300) at a temperature of 90-100oC and a pressure of 0.07 to 0.15 MPa. Passing steam extracts and essential oils azulene and condenses in the refrigerator, from which they mix with water and separated in the oil separator (Florentine).

One ton of bark receive from 6.6 to 15.3 kg of essential oil (substance) containing from 70 to 490 g Aslanov, amoralna in the form of a raw substance for extraction fraction azulenes and its subsequent use (in medicine, perfumery and cosmetics), as well as bioactive additives in a variety of new drugs based on plant forest raw materials.

Example 1. Crushed to the size of 1-2 cm bark spruce loaded into a boiling VAT installation with a capacity of 1-2 m3pass through it, the water vapor from the boiler, steam generator e-coat-300 at a temperature of 90oC and a pressure of 0.07 MPa for 8-10 hours. Passing steam removes azulene and essential oils and is condensed in the refrigerator, from which the mixture of them with Florentino water and is divided into Florentine (oil separator).

The oil layer is separated from Florentino water. Content azulenes in the essential oil determined by gas chromatography [5]. The content of chamazulene in the essential oil is 1.1%.

Example 2. The process is carried out analogously to example 1 with the same vegetable raw materials (spruce bark, crushed to a size of 1-2 cm), but with increasing temperature up to 100oWith increasing pressure to 0.15 MPa. The essential oil content in it azulenes in number to 3.22%.

Lowering the temperature to 85oWith leads to a drastic reduction of the yield of essential oils and accordingly reduce reduce azulenes (chamazulene) to ve the functions of substitution, which lead to complex rearrangements of electrons in the molecule, which leads to the formation of other compounds. Also, there is a decrease or absence of azulenes in fractions of essential oils.

The table presents data on the content of chamazulene in substance essential oil at different temperature distillation.

The method is as follows on the installation drawing.

Shredded bark waste of conifers from cuttings of the main and intermediate use, or from wood processing, for example, spruce loaded into a boiling VAT 1 (drawing) mobile units for periodic operation with a capacity of 1-2 m3pass through it, the water vapor from the boiler of a steam generator 2, for example of the type e-coat-300, at a temperature of 90-100oC and a pressure of 0.07 to 0.15 MPa. Passing steam extracts and essential oils azulene, condenses in the cooler 3, from which the mixture of them with Florentino water and is divided into Florentine - oil separator 4. Oil azulene accumulates in the oil receiver 5.

Thus, this process allows to obtain coniferous essential oils, containing more than 3% of chamazulene that gives reason to use oil as the amounts of the medicine, perfumery and cosmetics.
