Method for extracting podocarpus macrophyllus volatile oil based on microcapsule double-aqueous-phase method

The invention discloses a method for extracting podocarpus macrophyllus volatile oil based on a microcapsule double-aqueous-phase method. The method comprises the following steps: taking 100g of podocarpus macrophyllus powder and adding the podocarpus macrophyllus powder into an ethanol solution with the concentration of 40 percent according to the material/liquid ratio of 1 to 2; immersing at room temperature for 24h; performing suction filtration to obtain filtrate; adding beta-cyclodextrin which is 40 percent of the filtrate and Na2SO4 which is 15 percent of the filtrate into the obtained filtrate; stirring at 35 DEG C for 30min; centrifuging and standing; collecting a beta-cyclodextrin phase; centrifuging the collected beta-cyclodextrin phase to obtain a dextrin-shaped substance; adding absolute ethyl alcohol and stirring; then centrifuging again and collecting an ethanol phase; decompressing and concentrating the obtained ethanol phase to obtain the light yellow podocarpus macrophyllus volatile oil.
