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 . ocarp; C, D, E, sections of the seed; c, cotyledons; w, hypocotyl;v, epicotyl or plumule.—After Focke. slightly unequal, plumule 1 mm. in length; odorless, except on treat-ment with water, when an odor of hydrocyanic acid is emitted, or ofbenzaldehyde when the seeds have been kept for some time; tastebitter. Inner Structure.—See Figs. 132 and 133. Constituents.—Fixed oil 45 per cent; proteins 25 to 30 per cent;a glucoside, amygdalin, 1 to 3 per cent; and a ferment, emulsin,which acts upon amygdalin, decomposing it into a volatile oil (ben-zaldehyde or oil of bitter almond) and hydrocyanic acid. In addi-tion to the protein emulsin, there is another casein-like protein present,amandin, both of which act as emulsifying agents in the preparationof emulsion of almonds. Amygdalin, or a similar principle, is found in the young shootsand flower-buds, as well as seeds, of apricot, peach, plum, cherryand cherry laurel.
