It is often adulterated with cheaper oils, and especially with turpentine oil, the presence of which , may be detected by means of fractional distillation. Aniseed Oil. — ^The greater proportion of the commer- cial aniseed oil is d...istilled from the star anise (badiane), Illicium verum, which is cultivated principally in the South of China ; but a considerable amount is obtained from the true anise, Pimpinella anisum, originally a native of Asia Minor, but now grown in many European countries, notably Russia, in India and in South Americaj The oils derived from these two plants have^many chemical points of resemblance, both containing as -a main constituent the compound anethol. .
