Anisi aetheroleum is the oil obtained from Pimpinella anisuin L.(P.anisuin) by steam distillation.P.anisuin seeds were air-dried,and then the dry seeds were crushed,pulverized,and weighed in sequence for anise oil preparation.P.anisuin is one of the oldest medicinal plants that belong to family Apiaceae.The fruit of P.anisuin is harvested in August and September.P.anisuin is widespread in Asia,Africa and Europe.Local names of P.anisuin include anise,anisoon,roomy,saunf,sweet cumin and yansoon.The anise oil odour is aromatic while the oil tastes sweet.The average daily dose of Anisi aetheroleum is 0.3 g.transAnethole is the major ingredient of the anise oil.Anisi aetheroleum also displays a protective action against neurotoxicity.In addition.Anisi aetheroleum increases glucose absorption and reduces urine output in the rat.The plant oil have pharmacological(antimicrobial,hepatoprotective.anticonvulsant,anti-inflammatory,antispasmodic,bronchodilator.estrogenic,expectorant and insecticidal) effects and clinical effects on nausea,constipation,menopausal period,virus,diabetes,obesity and sedative action.Owing to the wide application of Anisi aetheroleum in pharmacological and clinical fields,it is recommended for more clinical trails to discover a new medication from the active constituents of the plant oil in the future to treat human diseases especially chronic ones.
