This article describes a new method for the determination of alkaloids and other medicinal drugs. This method involves the extraction of an organic base, forming an ion pair with an inorganic Co (SCN) ~ (2) _4 complex, and determining the diamond in the organic phase by atomic absorption spectroscopy at a wavelength of 241.0 nm. Studies have been conducted on the determination of pH, Co (SCN) for amilocaine, papaverine, epicrine, procaine, quinine, codeine, atropine, pilocarpine and avacan, The optimum conditions of the concentration of _4 ~ (2-), shaking time, the ratio of the solution phase, the extraction times and the standard linear range were as follows: The organic phase used was 1,2-dichloroethane. The standard deviation of this law is based on
