Abstract

We studied the effect of microwave fields on alcohol-alkaline extraction bast of a birch bark. It is shown that the maximum yield EV (>25%) is achieved when conducting microwave extraction, and the minimum duration of the filtration occurs when the following values of parameters: flow KOH 17% by weight of bast, the concentration of ethanol 10%, liquid module 17. These parameter values can be considered optimal.

Studies of the kinetics of microwave extraction at the optimum conditions of extraction process to determine the duration of the extraction. When this was controlled by the output of extractives (EV) and the duration of filtration. The total duration of microwave extraction was 15 min.

Studied the practical application of phloem extracts of birch to stimulate plant growth, and phloem after extraction as a structuring additives to the soil and potash fertilizers. Revealed a positive effect of seed treatment with the extract concentration of 10-4 g/l, starting from the 10th day of observations on the germination under conditions recommended by the standard. Solutions of higher concentration EV act as inhibitors. It was also observed that seeds treated with solutions of EV at any concentration, didn't decay. This implies that the extracts have antiseptic properties. It is shown that when added to the soil bast (0,5–1,5%) seed germination is improved. It is revealed that the more the content of the phloem in the soil, the higher the percentage of germinated seeds (maximum 45 %).
