Published: March 1994

A simple and sensitive (up to nanogram level) method to determine norepinephrine, serotonin and dopamine in rat brain is described. The amines are acetylated and the derivatives are resolved by thin layer chromatography (TLC) on silica high performance thin layer chromatography (HPLC) plates. Quantification is achieved by fluorescence densitometry at 415 nm excitation wavelength.

The construction of thin film heterostructures has been a widely successful archetype for fabricating materials with emergent physical properties. This strategy is of particular importance for the design of multilayer magnetic architectures in which direct interfacial spin-spin interactions between magnetic phases in dissimilar layers lead to emergent and controllable magnetic behavior. However, crystallographic incommensurability and atomic-scale interfacial disorder can severely limit the types of materials amenable to this strategy, as well as the performance of these systems.

January 2025

Department of Biomedical and Pharmaceutical Sciences, Graduate School, Kyung Hee University, Seoul, Republic of Korea.

Known for their diverse and potent physiological activities, natural products continue to be essential for the discovery and development of new drugs. This chapter explores the pivotal role of preparative thin-layer chromatography (Prep-TLC) in the isolation of natural products. This chapter begins with an understanding of the historical significance and structural complexity of natural products, and discusses the problems caused by complex mixtures present in extracts, as well as the multifunctionality, cost-effectiveness, and compatibility with different sample types of Prep-TLC to address these challenges.
