F. Barbato et al., ANALYSIS OF CALCIUM-CHANNEL BLOCKING DIHYDROPYRIDINES AND THEIR DEGRADATION PRODUCTS BY GAS-CHROMATOGRAPHY, Il Farmaco, 49(7-8), 1994, pp. 461-466
Seven dihydropyridine calcium blockers have been analyzed by GC. Simul
taneous analysis has been performed both by an isothermal and a gradie
nt method. Moreover, the proposed methods have been performed on the a
nalysis of daylight exposed methanolic solutions of considered compoun
ds; the ability of the systems in separate original compounds from day
light degradation products has been studied. The GC - MS spectra of ph
otodegradation products are discussed.
