1) Ultraviolet absorption spectra of the penicillin G and its related substances have been studied. Characteristic absorption band with penicillin G aq. solution lies between 260mμ and 270mμ which may be correlated with its chemotherapeutical active portion of the molecule.. 2) By measuring the optical density at 265mμ of the penicillin G solution whose concentration is unknown, its international units can be calculated by means of the following two equations.
