Plant. - Annual herb .3 M. (1°) high; dentate, pinnatifid; flowers white, small, umbels 8-14-rayed. Fruit, cremocarp, ovoid, pyriform compressed, grayish-green, slightly pubescent, 3-6 Mm. (1/8-1/4') long, 2-3 Mm. (1/12-1/8') broad; mericarps 2, usually cohering and attached to slender pedicel 2-12 Mm. (1/12-1/12') long with 5 filiform ridges and 15-45 vittae, summit with ring-like disk and 2 projecting styles; odor and taste agreeable, aromatic. Powder, yellowish-brown; microscopically - fragments of pericarp with vittae, tracheae, sclerenchyma-tous fibres of carpophore, cells of endosperm filled with aleurone grains, each usually enclosing a rosette aggregate crystal of calcium oxalate, 1-celled non-glandular hairs. Tests: 1. Heat 1 Gm. with potassium hydroxide T. S. (10) - no mouse-like odor (abs. of conium). 2. Incinerate - ash 9 p. c. Solvents: alcohol; boiling water partially. Dose, gr. 10-30 (.6-2 Gm.).

Adulterations. - Fruit: Earthy fragments, partly exhausted fruits, recognized by shriveled appearance, chiefly, however, with conium fruit (which resembles mostly the Russian anise), but odor and taste not aromatic - becoming mouse-like with solution potassium hydroxide even when 1 p. c. present; non-hairy; consisting usually of single smooth mericarps, grooved upon the face, 5-crenate ribs (ridges) with wrinkles between them, no vittae; Powder: Star-anise recognized by its peculiar sclerotic cells, earthy matter sinking when stirred in strong brine; Oil: Spermaceti 5-35 p. c, wax, petroleum, fixed oils, oils of turpentine and fennel, camphor (to raise congealing-point), alcohol, fenchone (fennel stearoptene); the two first insoluble in cold alcohol, whereas oils and camphor are mostly soluble; camphors recognized - by odor; alcohol - by milkiness to water; star-anise oil is the same chemically, but has a slight distinguishing smell and taste, also lower congealing-point (1°C.;34°F.).

Commercial. - Plant was known and cultivated by the Romans, while Theophrastus wrote of its aromatic properties; now grown

mostly in Malta, Spain, Italy, S. Russia, Greece, Chile. There are four varieties: 1, Spanish (Alicante), small, best, preferred; 2, German (French), larger; 3, Italian, exported via Leghorn; 4, Russian, very short, resembling conium most; that cultivated at home supplies largely our market.

Constituents. - Volatile oil (anethol) 1-3 p. c, fixed oil 3-4 p. c, choline, resin, sugar, mucilage, malates, phosphates, ash 7 p. c.

Oleum Anisi. Oil of Anise. Oil of Star Anise, official. - (Syn., 01. Anisi, Anise Oil; Fr. Essence d'Anis; Ger. Anisol, Anethol.) This volatile oil, obtained by distilling the ripe fruit of anise or star anise (lllicunn vemm), is a colorless, pale yellow, strongly refractive liquid, characteristic odor and taste of anise, soluble with not more than slight cloudiness in 3 vols. of 90 p. c. alcohol; sp. gr. 0.983, increasing with age; contains a liquid body - terpenes and methyl-chavicol, C10H12O, and a stearoptene, anethol, C10H12O, 80-90 p. c, upon which the value depends, being converted by exposure or oxidation with nitric acid into anisic acid; star anise oil is the same chemically, containing anethol 80-90 p. c, d-pinene, d-phellandrene, and possibly safrol, but congeals at 1° C. (34° F.), while anise oil at 10-15° C. (50-59° F.). Tests: 1. Laevorotatory (abs. of oils of fennel, caraway, coriander - dextrorotatory). 2. Shake with water in graduated tube - volume should not diminish; drop into water - no milkiness unless agitated (abs. of alcohol). 3. Alcoholic solution neutral; with a drop of ferric chloride T. S. - no blue or brown color (abs.- of phenols). Impurities: Heavy metals, oil of fennel, phenols. The label must indicate definitely its specific source, and if solid material has separated, carefully warm the oil until liquefied and thoroughly mix before dispensing. Should be kept dark, in well-stoppered, amber-colored bottles. Dose, eij-5 (.13-.3 Ml. (Cc.)).

Anethol. - The methyl ether of para-propenyl phenol obtained from this and other oils by fractioning, chilling, crystallizing; practically identical with the oil.
