A rapid, simple, stability-indicating assay procedure for norgestimate [(+)-13-ethyl-17-hydroxy-18,19-dinor-17 alpha-pregn-4-en-20-yn-3-one oxime acetate], a new progestational agent, and ethinyl estradiol (19-nor-17 alpha-pregna-1,3,5(10)-trien-20-yne-3,17-diol) in single- and composite-tablet analyses was developed using high-performance liquid(More)
A stability-indicating assay procedure for the determination of norethindrone on the surface of Red Delicious apple slices was developed. The apple slice is homogenized in pH 10 borate buffer solution and norethindrone is then partitioned into chloroform using a diffusion chamber that has a membrane that is permeable to hydrophobic compounds separating the(More)
