title: Gas-liquid chromatographic analysis of lynestrenol in contraceptive tablets.
abstract: A simple procedure for the estimation of lynestrenol in contraceptive tablets is described. The method consists of extraction of the hormone into dichloromethane followed by g.l.c. of the resulting solution. 3 alpha-Etiocholanol-17-one is demonstrated as a suitable internal reference standard.
