[Eng., ., piper; -ine.] Chem.: C17H19NO3. An alkaloid discovered by Oersted in 1819, in black and long pepper, and readily obtained by exhausting pepper berries with alcohol of specific gravity 0833. It crystallizes in colorle , tetragonal plates, destitute of odor or taste; specific gravity, 1'1931 at 18°, is insoluble in water, very soluble in alcohol and ether, its alcoholic solution having a sharp, peppery taste, and melts at 100° to a pale yellow, limpid oil. It is but a weak base, and forms very few salts. With iodine it unites, forming iodide of piperine, 4C17H19NO313, which crystallizes in shining, bluish-black needles soluble in alcohol. pl-per-1-tæ, s . pl . [Fem. pl. of Mod.
