Extraction is carried out for two stages. In the first stage extraction is carried out with condensed carbon dioxide under pressure 6.0-7.0 MPa for 3-5 h at temperature 22-26 C followed by isolation of carbon dioxide extract. In the second stage carbon dioxide extract is treated with 70-94% ethyl alcohol solution at temperature 25-60 C for 5-10 min to yield alcoholic extract from which alcohol-soluble and alcohol-insoluble fractions are isolated. Prepared products of apiculture can be used in medicine, cosmetics, veterinary science and as independent medicinal agent. EFFECT: reduced fire hazard of method, stable products. 3 ex
