Extractum Podophylli Fluidum (U. S. P.)—Fluid Extract of Podophyllum.
SYNONYMS: Fluid extract of May apple, Fluid extract of mandrake.
Preparation.—"Podophyllum, in No. 60 powder, one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]; alcohol, water, each, a sufficient quantity, to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Mix eight hundred cubic centimeters (800 Cc.) [27 fl℥, 25♏] of alcohol with two hundred cubic centimeters (200 Cc.) [6 fl℥, 366♏] of water, and, having moistened the powder with three hundred cubic centimeters (300 Cc.) [10 fl℥, 69♏] of the mixture, pack it firmly in a cylindrical percolator; then add enough menstruum to saturate the powder and leave a stratum above it. When the liquid begins to drop from the percolator, close the lower orifice, and, having closely covered the percolator, macerate for 48 hours. Then allow the percolation to proceed, gradually adding menstruum, using the same proportions of alcohol and water as before, until the podophyllum is exhausted. Reserve the first eight hundred and fifty cubic centimeters (850 Cc.) [28 fl℥, 356♏] of the percolate. Distill off the alcohol from the remainder by means of a water-bath, and evaporate the residue to a soft extract; dissolve this in the reserved portion, and add enough menstruum to make the fluid extract measure one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]"—(U. S. P.).
