FIELD: essential oils industry.
SUBSTANCE: invention relates to the essential oil industry. Method involves grinding anise fruits, extraction of ground raw material with an organic solvent in a Soxhlet apparatus and evaporation of the solvent. Organic solvent used is an easily boiling liquid – methyl ether of perfluorobutane at a raw material/solvent ratio of 1:4.5–9.0 wt/wt; extraction of the raw material is carried out for 1–5 hours. Obtained extract is evaporated to obtain an oil extract which is treated with ethanol 96 % vol/vol, the ratio of oil extract/ethanol = 1:2 vol/vol, then mixture of oil extract and ethanol is centrifuged to separate solution of essential oil in ethanol, which is evaporated under vacuum at 40 °C to produce purified essential oil of anise.
EFFECT: invention allows to develop effective ecologically clean method for extraction of essential oil of anise, which does not require specialized and complex equipment.
