Analysis of multiple sweeteners and their degradation products in lassi by HPLC and HPTLC plates

A solid phase extraction method using C18 cartridges was standardized for the isolation of multiple sweeteners (aspartame, acesulfame-K and saccharin) and their degradation products (diketopiperazine, Lphenylalanine, acetoacetamide and 2-sulfobenzoic acid) from lassi. Analytical conditions for HPLC were standardized over C18 column using UV detector for the simultaneous separation and estimation of multiple sweeteners and their degradation products in lassi sample isolates. A simple cartridge free method was developed for the isolation of sucralose from lassi. Method was also standardized for qualitative detection and quantitative estimation of sucralose over amino and silica gel plates of HPTLC.
