Fruit -- Anisum, Anise (Seed), N.F. -- The dried ripe fruit with not more than 3 p.c. of other fruits, seeds or foreign organic matter, yielding not more than 1.5 p.c. of acid-insoluble ash; cremocarp, broadly oval compressed, mericarps usually cohering and attached to slender pedicel 2-12 Mm (l/12-1/2') long, apex with 2 styles, grayish-green, seldom brownish, slightly pubescent; odor and taste agreeable, aromatic -- Russian variety closely resembles conium. Powder, yellowish-brown -- numerous fragments of pericarp with yellowish oil tubes, tracheae, carpophore fibers, endosperm cells, aleurone grains, calcium oxalate rosette aggregates, non-glandular hairs. Test: 1. Heat 1 Gm. with potassium hydroxide T.S., (10) -- no mouse-like odor (abs. of conium). Illicium verum. - Magnoliaceae: Small tree, 3-6M. (10-20 degrees high, branched; leaves pellucid-punctate; flowers greenish-yellow; Fruit, star-shaped -- 8 stellately arranged boat-shaped carpels, 8 Mm. (1/3') long, brown woody, wrinkled, each carpel containing 1 glossy-brown seed; solvents: alcohol, boiling water. Dose, gr. 10-30 (.6-2 Gm.)


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, U.S.P. -- This volatile oil 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, CHO, and a stearoptene, anethol, CHO, 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 degree C. (34 degrees F.), while anise oil at 10-15 degrees C. (50-59 degrees F.). Tests: 1. Levorotatory (abs. 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, mij-5 (.l3-.3 cc.).

Anethol. Anethol, N.F. -- The methyl ether of para-propenyl phenol CHCHOCH, obtained from this and other oils (star anise, fennel), by fractionating, chilling, crystallizing; practically identical with the oil. It is a colorless, faintly yellow, highly refractive liquid at 23 degrees C. (73 degrees F.), sweet taste and aromatic odor of anise, solidifies at 20 degrees C. (68 degrees F.) to white glistening, crystalline mass, remelting at 22 degrees C. (72 degrees F.), soluble in ether, chloroform, alcohol (2), almost insoluble in water; sp. gr. 0.985, boils at 235 degrees C. (455 degrees F.); optically inactive, levorotatory (if from anise), dextrorotatory (if from fennel). Test: 1. Shake 10 cc. with 50 cc. saturated aqueous solution of sodium bisulphite in graduated cylinder, let stand 6 hours--no diminution of anethol volume nor crystalline deposit

(abs. of aldehydes). Should be kept dark, in well-stoppered, amber-colored bottles. Dose, mij-5 (.13-.3 cc.).



Earthy fragments, partly exhausted fruits, recognized by shriveled appearance, chiefly, however with conium fruit (which resembles mosly 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;


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, 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 degree C.; 34 degrees F.).


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.
