实验方案
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.
