Eco-friendly liquid chromatographic methods for measuring ergotamine (EGT) are scant in the published database. Accordingly, the goal of the current study was to develop a high-performance thin-layer chromatography (HPTLC) method for fluorescence detection of EGT in commercially available tablets. This approach was based on the application of ethyl alcohol-water (80:20 /) as the eco-friendly eluent mixture. The fluorescence detection of EGT was carried out at 322 nm. The greenness score of the present approach was evaluated by "Analytical GREENness (AGREE)" technology. The present approach for measuring EGT in the 25-1000 ng band range was linear. The present assay for fluorescence detection of EGT was validated successfully by ICH guidelines for various parameters. The method was found to be rapid, sensitive, eco-friendly, and stability-indicating. The computed AGREE index for the current strategy was 0.84, displaying outstanding greenness features. The present methodology successfully separated the EGT degradation products under forced-degradation circumstances, exhibiting its stability-indicating qualities and selectivity. An amount of 99.33% of EGT was found in commercial formulations, indicating the validity of the current method for pharmaceutical analysis of EGT in commercial products. The results showed that EGT in commercial products might be regularly measured by the existing method.
在已发表的数据库中,用于测量麦角新碱(EGT)的环保型液相色谱方法很少。因此,本研究的目的是开发一种用于在市售片剂中荧光检测 EGT 的高效薄层色谱(HPTLC)方法。该方法基于应用乙醇-水(80:20 /)作为环保洗脱混合物。EGT 的荧光检测在 322nm 下进行。通过“分析绿色度(AGREE)”技术评估当前方法的绿色度得分。本方法用于测量 25-1000ng 波段范围内的 EGT,呈线性。根据 ICH 指南,对用于荧光检测 EGT 的本测定法成功进行了各种参数的验证。该方法快速、灵敏、环保且具有稳定性指示。当前策略的计算 AGREE 指数为 0.84,显示出出色的绿色特征。本方法在强制降解情况下成功分离了 EGT 降解产物,显示出其稳定性指示特性和选择性。在商业制剂中发现 EGT 的含量为 99.33%,表明当前方法可用于商业产品中 EGT 的药物分析。结果表明,现有的方法可以定期测量商业产品中的 EGT。
