Development and validation of a stability-indicating HPTLC assay method for idebenone

Summary A simple, selective, precise, and stability-indicating high-performance thin layer chromatographic (HPTLC) method has been established and validated for the analysis of idebenone in bulk drug and formulations. The compounds were analyzed on aluminum-backed silica gel 60 F254 plates with petroleum ether-methanol (4:1, υ/υ) as mobile phase. Densitometric analysis of idebenone was performed at 282 nm. Regression analysis data for the...
