ABSTRACT
Piperine and piperlongumine, alkaloids having diverse biological activities, commonly occur in roots of Piper longum L., Piperaceae, which have high commercial, economical and medicinal value. In present study, rapid, validated HPTLC method has been established for the determination of piperine and piperlongumine in methanolic root extract and its commercial formulation 'Mahasudarshan churna®' using ICH guidelines. The use of Accelerated Solvent Extraction (ASE) as an alternative to conventional techniques has been explored. The methanol extracts of root, its formulation and both standard solutions were applied on silica gel F254 HPTLC plates. The plates were developed in Twin chamber using mobile phase toluene ethyl acetate (64, v/v) and scanned at 342 and 325 nm (λmax of piperine and piperlongumine, respectively) using Camag TLC scanner 3 with CATS 4 software. A linear relationship was obtained between response (peak area) and amount of piperine and piperlongumine in the range of 20-100 and 30-150 ng/spot, respectively; the correlation coefficient was 0.9957 and 0.9941 respectively. Sharp, symmetrical and well resolved peaks of piperine and piperlongumine spots resolved at Rf 0.51 and 0.74, respectively from other components of the sample extracts. The HPTLC method showed good linearity, recovery and high precision of both markers. Extraction of plant using ASE and rapid HPTLC method provides a new and powerful approach to estimate piperine and piperlongumine as phytomarkers in the extract as well as its commercial formulations for routine quality control.
