RESUMO

The raw material of mestranol was examined for preparation of the "Mestranol Reference Standard". Analytical results for the sample were as follows: UV spectrum indicated absorption maxima at 279 and 287 nm and absorptivity at 279 nm E1%1cm 66; IR spectrum indicated specific absorption at 1612, 1578, 1505, 1253, and 1060 cm-1; optical rotation +3.9 degrees; melting point 153.1 degrees; loss on drying 0.03%; TLC and HPLC analyses indicated one impurity, respectively; the purity was assumed to be 99.3% by HPLC analysis. Based on the results, the present raw material was authorized to be the Reference Standard of the National Institute of Hygienic Sciences.

RESUMO

PIP: A collaborative study of the analysis of mestranol in combination with norethindrone or norethynodrel by column chromatography and ultraviolet determination is presented. The study consisted of 4 samples which were a commercial norethindrone tablet, a synthetic norethindrone mixture, a commercial norethynodrel tablet, and a synthetic norethynodrel mixture. The samples were analyzed by 13 collaborators. Average mestranol recoveries were 100.4, 99.9, 98.7, and 101.2%, respectively.^ieng
