(54) COMPOSITION OF CONSERVATING LIQUID FOR STORAGE OF PLANT PREPARATIONS

The invention relates to applied botany, namely to preservative liquid compositions for storing plant macro and micro preparations under a cover glass.

Known compositions for the preservation of plant-based liquids under a cover glass (Canadian balsam, glycerin-gelatin, Toyer liquid, etc.) 1.

For the preparation of the preservative composition and the storage of the plant microsample under the cover glass, myo-step manipulations are required, which require a considerable amount of time (more than a week). In addition, Canadian balsam and Goyer liquid are expensive and scarce products.

The composition of the preservative liquid for storing herbal preparations under a cover glass is known, which is a mixture of 50 ml of glycerin and 7 g of gelatin 2,

The disadvantages of this composition are the use of scarce expensive products (glycerin, gelatin) and complex application techniques.

In a number of cases, cuts heated in the compositions are deformed, their color changes, shrinks, and their straightening is almost impossible. In order to guarantee long-term preservation, it is necessary to cover the glass with asphalt varnish.

The aim of the invention is to reduce the cost of the drug and simplify the technology of its use.

The goal is achieved by introducing silicate glue and distilled water into a known composition of a preservative fluid based on glycerin in the following ratio of components,%:

Glycerin 10-40

Silicate adhesive30-80

Distilled Water Else

Recommended optimal composition. Content of components in a volume ratio of 4: 1: 1.

The composition is prepared as follows. 100 g of office silicate glue is displaced in a glass dish with 20 ml of distilled water, after which the mixture is added to -. "V irV 20 ML of glycerin and the composition of the vials in the" "2-3 min. The finished composition of hrSHyT and ground bottles or cans. Example G. ABtoMiaTHiecKSe The rubbing of parts of plants after washing with water is loaded into 2-3 drops of the composition, which is applied prior to washing; aSubstantial glass, then covered with a cover glass. After 2-3 hours, the composition dries out and the drug becomes almost constant. The composition allows preserving anatomical sections without completely destroying the structure of the object. Moreover, it creates the possibility of kQHiepBianjiH of isolated leaf veins and pidermal films under a whole 24x24 mm cover glass. The cost of the proposed composition is reduced by more than 60% due to the simplified technology (lack of heating, hot filtration) of its preparation by more than 60%. The shelf life of the preparation due to silicate glue increases by Shlet The changes in the structure of the slice are completely excluded, since cold composition is used. In addition, the proposed composition is transparent,. - "..7., .4 That allows to obtain a clear picture of the drug, and does not crack. Commercial composition can be used at any time in its natural form, its storage time in a closed vessel is not limited. Claims of the invention The composition of a preserving liquid for storing herbal preparations, including glycerin, characterized in that, in order to reduce its cost and simplify its use, it additionally contains silicate glue and distilled water in the following ratio of components, vol.%: Glycerin 10-40 Silicate glue 30-80 Water is distilled Else Sources of information, s Taken into account during the examination of G.
