A METHOD FOR PRODUCING AND RESEARCH OF BIRCH BUDS EXTRACTS

Abstract

An extraction of birch buds was made using two types of extractants - with water and mixture of isopropyl alcohol: water with variable ratio. An ultrasound was used to intensify the extraction process. The effect of ultrasound on the quality of the extracts was evaluated on the various stages of the process. Experimentally the optimal mode of obtaining extracts of birch buds with high output of extractive substance was selected.
