Scientific and applied pharmacognosy intended for the use of students in pharmacy, as a hand book for pharmacists, and as a reference book for food and drug analysts and pharmacologists . iptical vittse, the cells of the pericarpseparated from the seed-coat and forming a large elliptical cavity;endosperm distinctly reniform in outline and consisting of tabularor polygonal, thick-walled cells, containing numerous large aleuronegrains, each with a rosette aggregate or prism of calcium oxalate. 488 SCIENTIFIC AND APPLIED PHARMACOGNOSY Powder.—Light brown; calcium oxalate crystals numerous, to mm. in diameter, mostly in rosette aggregates, eitherisolated or in aleurone grains; sclerenchymatous fibers irregularlycurved, having thick, yellowish, lignified walls and numerous simplepores; globules of fixed oil numerous; fragments of light-yellowvittse few, associated with elongated, polygonal, epidermal cells. Constituents.—Volatile oil to 1 per cent; fixed oil about 13per cent; tannin; calcium oxalate; ash about 5 per cent. Thevolatile oil consists of about 90 per cent of d-linalool (coriandrol),about 5 per cent of d-pinene and some other Fig. 209.—Cross-section of a mericarp of conium: c, c, commissural surface; e,portion without secondary ribs; o, portion showing slight development ofsecondary rib; o, secondary rib; v, fibrovascular bundle of pericarp (m);t, t, layers containing coniine; a, endosperm; b, tissues of the embryo.—After Fliickiger. The unripe fruits are said to yield a volatile oil that has a fetid,disagreeable odor, which it loses on keeping. Standard of Purity.—Coriander seed is the dried fruit of Corian-drum sativum L. It contains not more than 7 per cent of total ash,nor more than per cent of ash insoluble in hydrochloric acid.(U. S. Dept. Agric.) Allied Plants.—Bombay or Indian Coriander are the fruits of avariety of Coriandrum sativum imported from Bombay. The fruitsare oval and yield less volatile oil
