In this article we present several HPTLC applications and analytical standards for ginsenosides.
HPTLC is an efficient method to determine Steviol Glycosides content in Stevia using our HPTLC plates and reference materials, including a new introduced Stevia extract reference material.
HPTLC was used to analyze caffeine in coffee. Filtration of coffee through a PTFE syringe filter was the only sample preparation. Quantitation was conducted with a TLC scanner.
Powdered black pepper was chosen as example for dietary supplements, being a source for pierine. It is tested according to the current United States Pharmacopeia (USP) guidelines using HPTLC and HPLC.
In the present study we demonstrate compliance of silica gel 60 F254 HPTLC plates with USP requirements, and how HPTLC plates are suitable for the Sildenafil citrate-Limit of Imidazole test.
