The article presents the results of a study of the biological activity of the sap of the needles of Norway spruce ( Picea abies L.), Scots pine ( Pinus sylvestris L.) and Japanese yew ( Taxus cuspidata Siebold et Zucc. Ex Endl.). The highest antimicrobial activity of the Japanese yew’s needle sap against human pathogens and phytopathogens was established: the values minimum inhibitory concentration, the minimum bactericidal concentration and the minimum fungicidal concentration were 0.0313 and 0.0078%, respectively. Expressed antioxidant properties and membrane-protective activity of Scots pine needles sap were revealed in comparison with Norway spruce both in winter and in summer. The Japanese yew needle sap had the most pronounced antioxidant properties. With a decrease in the concentration of Japanese yew needle sap, its ability to protect membranes from peroxide hemolysis increased. Its high cytotoxicity and lack of selectivity in relation to tumor cells have also been established.
