Analyses of Drugs and Chemicals by Infrared Absorption Spectra. I. Quantitative Analyses of Santonin, Thymol, Tetrachloroethylene, and Ascaridol in Mixed Drugs.

Abstract

An infrared method has been developed for the simultaneous determination of santonin, thymol, tetrachloroethylene, and ascaridol (main component of chenopodium oil) in a mixture. The manipulations are simple and rapid to perform, and accuracy and precision of analyses are good.
