Accurate quantitative analysis of trace principles in extracts of biologically active natural medicines relies on the use of reliable internal standards (ISs), which, in the case of liquid chromatography-mass spectrometry (LC-MS) analysis, commonly correspond to isotope-labeled stable analogues of the analytes. Herein, we describe the synthesis of salacinol-1,1,5,5-C-d(4) (7), an isotope-labeled stable analogue of salacinol (1), which, in turn, is a potent alpha-glycosidase inhibitor isolated from Salacia (a traditional Ayurvedic medicine), and show that the isotopic purity of the labeled standard is satisfactory for LC-MS analysis.
