| Abstract: | In order to determine the best extraction process of alpine pine needle volatile oil of Changbai Moun- tain by microwave-assisted extraction,taking alpine pine needle as test materials, the extraction condition and antibacterial effect of pine needle volatile oil were studied with orthogonal experiments. The results showed that the highest extraction rate of pine needle volatile oil was 0. 138%, the best extraction combination was A2 B2 C3 D1, that＇s ethanol concentration, solid-liquid ratio of 1120, microwave power of 700 W and extraction time of 40 s;with decreasing concentration of pine needle volatile oil,bacteriostatic activity was increasing. |
