High Performance Thin-Layer Chromatography-Mass Spectrometry Evaluation of Sanguinarine and Dihydrosanguinarine from Argemone mexicana Seeds in Edible Mustard Oil

In this present study, a simple, rapid, cheap, sensitive and reproducible HPTLC-MS Method has been developed for the identification of two important bioactive compounds, Sanguinarine and Dihydrosanguinarine in Argemone mexicana Linn seeds. The work further discussed and developed a sensitive HPTLC – MS method to analyse the adulteration and/or contamination of argemone oil in the edible mustard oil by spiking Sanguinarine and Dihydrosanguinarine as biomarkers. The n-hexane: diethyl ether (1:1 v/v) solvent system has been used as an extraction medium to extract the Sanguinarine and Dihydrosanguinarine from the seeds followed by HPLC-MS detection.The CAMAG HPTLC system modules consisted with ATS-4, ADC-2, visualizer-2, TLC scanner-4; Derivatizer and TLC-MS interface-2 have been used for sample application, HPTLC plate development, plate photo documentation, scanning of plate, spraying of derivatization reagent and elution of biomarkers directly from HPTLC plate respectively. The n-hexane: acetone (23:7, v/v) and dragendorff’s reagent has been used as mobile phase and derivatization reagent respectively. The UV- spectra and MS data confirmed the detection of selected biomarkers in the samples/spiked samples. Thus, the work highlights the use of HPTLC-MS to develop simple and routine method for the sensitive detection of Sanguinarine and Dihydrosanguinarine in Argemone mexicana seeds and able to become bases to these biomarkers’ evaluations in other samples such as various edible oils, agro-products, drugs and biomedical products etc.
