Excerpt from The American Journal of Pharmacy, 1883, Vol. 55 Seeing that the gummy matter is the chief obstacle to exhaustion, the writer sought to decompose it, in a preliminary operation, by means of dilute sulphuric acid. F ailing With this, ammonia was tried with a little success; but having accidentally added some borax to the ammoniacal mixture a rapid coagulation was notioed. Upon this, powdered nux vomica was mixed With borax and percolated with a menstruum composed of equal measures of alcohol and water, and, although absolute exhaustion of the powder was readily achieved, the percolate possessed such an obstinate turbidity that the process, other wise so satisfactory, was yet a failure. Borio acid, applied in a similar manner, was as inefficient as other acids previously tried. It was next resolved to test potassium citrate, which insured a satisfactory product, and absolute extraction of the drug. Deeming a simpler saline body more appropriate and obtainable, the writer resorted to sodium chlo ride, and attained, above all others, the most perfect result.
