Syrupus Tolutanus The official formula directs that a strongalcoholic solution of balsam of tolu be mixed with sugar and pre-cipitated calcium phosphate, the alcohol being subsequently evapor-ated spontaneously in a warm place; the residue is triturated withcold water and filtered through paper, and to the filtrate, heated toabout 60° C. (140 F.), the remainder of the sugar is added anddissolved by agitation. The short contact of cold water with thefinely-divided balsam of tolu will scarcely dissolve much of theodorous principles, and the heating to 60° C. appears more appro-. SYBUPS. 223 priate before than after filtration of the mixture, as in the latter caseit simply facilitates solution of the sugar, which is equally wellaccomplished in the cold. If all the alcohol be allowed to remain,as in the case of syrup of orange, and the aqueous mixture be setaside, with frequent agitation, for six or eight hours, before filtration,a much finer flavored syrup will be obtained, since the presence of5 per cent, of alcohol increases the solubility of the balsamic prin-ciples in the water. In case the alcohol is retained, the water andsugar ordered in the official formula must be reduced correspondingly,to 450 Cc. and 800 Gm., respectively. 8. Syrupus Zingiberis. According to the Pharmacopoeia, syrup ofginger should be prepared from fluid extract of ginger, by mixingthis with precipitated calcium phosphate, evaporating the alcohol,mixing the residue with water, filtering, and dissolving sugar in thefiltrate.
