Desenvolvimento e validação de método para o doseamento de tibolona em cápsulas por cromatografia líquida de alta eficiência

Abstract: Recebido em 8/8/11; aceito em 28/11/11; publicado na web em 23/1/12 DEVELOPMENT AND VALIDATION OF ANALYTICAL METHOD FOR DETERMINATION OF TIBOLONE IN CAPSULES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY. Tibolone is a synthetic steroid used for prevention of bone loss and treatment of menopause symptoms. This article describes the development and validation of an analytical method to quantify tibolone in capsules using high performance liquid chromatography with UV detection. After chromatography conditions are e… Show more

“…Table 9: Influence of temperature, column provider and the mobile phase flow, the robustness of the measurement method of thymol. The accuracy test is to prove the efficacy of the method for quantifying the analyte in the sample [22]. According to Brito [23], the accuracy is expressed as a percentage of systematic error inherent in the process.…”

“…In the chromatographic analyzes the wavelength was 204 nm and 205 nm and the solvents employed as mobile phase were acetonitrile and water (65:35 v/v), (60:40 v/v), and acetonitrile, water and methanol (60:30:10 v/v). (11,12,13). A secondary standard was then prepared to test different concentrations to determine the one to present the most satisfactory results.…”

“…The results obtained for the analysis of pharmaceutical samples with the proposed method were compared to those obtained by a method using a high-performance liquid chromatography with a ultraviolet detector (HPLC-UV-Vis), adapted from a previous work. [14] The HPLC system was composed of a Hitachi pump L-2130, Hitachi LC-4250 UV-VIS detector and a Shim-pack CLC-ODS (octadecylsilane) column (25 mm × 4.6 mm; Shimadzu). The mobile phase was composed of acetonitrile and water (70 : 30, v/v) at a flow rate of 1.0 mL min À 1 .…”

“…[11][12][13] The determination of TIB in biological and pharmaceutical samples using chromatographic methods has been shown in the literature. [5,[14][15][16][17][18][19][20][21][22] Only one study by GC-MS showed TIB determination in human saliva and none of its metabolites were found. [12] However, these methods involve time-consuming, high cost instrumentation, difficulties for use in on-site analysis for doping control and often require the use of various organic solvents.…”
