A Rapid and Sensitive Stability-Indicating Eco-Friendly HPTLC Assay for Fluorescence Detection of Ergotamine

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 v/v) 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(-1) 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.

Automated summary

A high-performance thin-layer chromatography (HPTLC) method with fluorescence detection was developed for measuring ergotamine (EGT) in commercially available tablets. The method utilized an eco-friendly eluent mixture and showed excellent linearity in the 25-1000 ng band(-1) range. The method was validated successfully and exhibited rapid, sensitive, and stability-indicating characteristics. Additionally, the method was rated highly for its "greenness" based on AGREE technology. The method also achieved successful separation of EGT degradation products and accurately measured EGT content in commercial products.
