Definitions
- the present invention relates to the field of high-tech wood-chemical wood processing.
- the invention provides a method for isolating valuable physiologically active compounds from tree wood, including extracts enriched in lignans and flavonoids (lignan-flavonoid complexes), as well as separated lignans and flavonoids intended for subsequent use in the preparation of dietary supplements and chemical-pharmaceutical products.
- the level of technology including extracts enriched in lignans and flavonoids (lignan-flavonoid complexes), as well as separated lignans and flavonoids intended for subsequent use in the preparation of dietary supplements and chemical-pharmaceutical products.
- Lignans and flavonoids belong to the class of phenolic compounds contained in different parts of plants, for example, in coniferous wood. Chemical extracts containing derivatives of lignans and flavonoids and preparations based on them are widely used in medicine and cosmetics, the food industry, as agrochemical preparations in the production of plant products, as well as in other areas.
- One of the compounds of interest related to lignans is secoisolariciresinol (CEKO).
- CEKO secoisolariciresinol
- DHA dihydroquercetin
- DHA DHA has been widely studied in research laboratories to determine the areas of its practical use. In Russia, DHA is most widely used in a number of biologically active drugs (for example, Kapilap, Flukol, and others) and some foods, which is associated with high antioxidant, hepatoprotective, immunostimulating, antimicrobial, and other practically beneficial properties of this connections.
- a growth and development regulator for agricultural crops has been created, commercialized under the commercial designation Lariksin (RF patent X ° 2229213; RF patent
- SECO is also a very promising drug for practical use, especially for the production of medicinal and biologically active drugs, as well as functional foods, due to the antioxidant, anti-inflammatory, phytoestrogenic, antimicrobial, and other beneficial properties of this compound.
- a pharmaceutical composition WOO ⁇ / 020254
- CEKO isolated from the plant Stereosperitis retopatitis
- functional foods WO02 / 080702
- hepatoprotective, anti-cancer drugs US 2006/0035964
- other drugs including CEKO
- knotty zones and branches of coniferous trees contain significant amounts of phenolic compounds [V. Nolmbom, S. Eskermap, P. Eklupd, J. Nemmipg, L. Nisula, M. Reupapep, R. Sjoholm, A. Supdberg, K. Supdberg, S. Willf ⁇ g, «Knots tgees Ip - A pew rish sourse ° F lignans» , Rhuthoshetistr ⁇ Reviws 2: 331-340, 2003.).
- the disadvantages of the described method include the following technical limitations.
- the proposed conditions are designed to single out a single target product, a representative of the lignan class of 7-hydroxymatayrene (“HMR”).
- HMR 7-hydroxymatayrene
- the wood of coniferous trees usually contains more than one component related to phenolic compounds, and such components do not belong only to the class of lignans.
- wood also contains representatives of the class of flavonoids, as well as lignan derivatives, which have great practical value.
- the economic feasibility of processing the specified type of wood raw material requires the development of methods for the simultaneous extraction of compounds of different classes, such as lignans and flavonoids, for their further use.
- the polar solvent used in this method is generally defined by indicating the dielectric constant (which must be greater than 3 at 25 ° C).
- These technically important solvents such as diethyl ether, chloroform and methylene chloride (their dielectric permeabilities are 4.34, 4.70 and 8.9, respectively) correspond to the specified dielectric constant, in which DHA is very soluble, which does not allow the use of these solvents for the extraction of DHA .
- the present invention is to develop a method of separation of phenolic compounds from wood, devoid of these disadvantages.
- the use of the proposed method opens up broad prospects for the production of a wide range of dietary supplements, chemical and pharmaceutical products and other products.
- the ground wood of the knotted zone is extracted with a non-layered mixture of an organic solvent with water, with an organic solvent content of 50-75%, to obtain an extract containing SKO and DHA, the extract is processed to remove the solvent to obtain the final mixture containing SKO and DHA.
- Washing the ground wood of the knot zone with alkane as in the well-known method [US 2004/0199032 of October 7, 2004], or with a current of CO 2 (including under supercritical fluid extraction) allows only the simplest low molecular weight organic molecules to be extracted from the wood pulp compounds that do not affect the efficiency of extraction of a mixture of DHA and SECO in the experimental conditions of the present invention.
- the resulting mixture containing SECO and DHA is further subjected to selective extraction and crystallization, to isolate purified target compounds.
- the extract containing secoisolaricizininol and dihydroquercetin is further processed to remove non-polar components, the supernatant is removed, and the resulting residue is chromatographed on a layer of silica gel, followed by removal of the eluate, obtaining a dry mixture of secoisolaricrizinol and dihydroquercetin.
- coniferous wood can be used as wood, preferably larch (Larix), in particular, Siberian larch (Larih sibirivic ⁇ ) and Dahurian (Larih dahiri ⁇ ) and fir ⁇ Abies), in particular, Siberian fir (Abies sibiriri), and “white pears” are used as the knotty zone of wood.
- the highest extraction efficiency of SECO and DHA is achieved using mixtures of organic solvent and water, and lower in pure organic solvent.
- solubility is lower in pure water (not shown in Fig. 3-8), in which the target compounds have a very limited solubility (dissolution in water requires heating). Therefore, the most important property of the used organic solvent according to this invention is its ability to mix with water in the range of these ratios, giving a homogeneous mixture with the required dissolving activity.
- the analysis of solvents according to this invention shows that their polarity is characterized by a dielectric constant value from 10 to 40 at 25-30 ° C.
- Acetone can be used as an organic solvent, while its content in a mixture with water is from 50 to 75%, preferably from 60% to 70%.
- isopropyl alcohol can be used as an organic solvent, while its content in a mixture with water is from 50 to 75%, preferably from 60% to 70%.
- organic solvent for example ethyl alcohol, satisfying the above characteristics, and the solvent content in a mixture with water ranges from 50 to 75%, preferably from 60% to 70%.
- the key advantage of the present invention is to provide an effective simultaneous extraction from the pulp both the compound of a number of lignans and the flavonoid compound of practical interest for use as a mixture or after separation.
- the advantage over the known method is also the ease of isolating the target compounds of the present invention, which does not require special drying of the extracted wood (in a known method, freeze drying), grinding frozen wood pulp and washing with alkane before extraction with an aqueous-organic mixture.
- the outputs of DHA in the conditions of this invention correspond to the best known methods of obtaining this compound from natural objects (for example, according to the methods described in the following sources: Nifantiev E.E.,

- the extracts enriched with lignans and flavonoids are widely used for the production of dietary supplements and chemical-pharmaceutical products of various types.
- the corresponding biological activity of the lignan-flavonoid complexes is determined by the content of lignified and flavonoid components in them, as demonstrated by the examples below, which do not limit the scope of the invention.
- the antioxidant properties of lignan-flavonoid complexes are determined by the total content of lignan (CEKO) and flavonoid (DHA) components in them.
- Table 1 demonstrates the antioxidant properties of DHA, CEKO, as well as their complexes, extracted from the Knotwood larch mass according to this invention (the description of the experiment is given in Example 18). From Table 1, it can be seen that equimolecular amounts of DHA and SECO exhibit the same antioxidant activity, as do lignan-flavonoid complexes containing the same total amount of lignified (CEKO) and flavonoid (DHA) components in them.
- CEKO isolated lignan component
- Table 2 shows the extragenic activity of CEKO, as well as the complexes of CEKO and DHA, extracted from the Knot of larch according to this invention (the experiment is described in Example 19).

- Analysis of the chromatograms suggests that the extraction with mixtures with an acetone content in the range from 50% to 75%, in particular from 60% to 70%, achieves the most effective extraction of DHA and SECO. With an increase in the content of acetone in the extractant over 75%, or with a decrease below 50%, the content of DHA and SECO in the extract decreases.
