Short summary
The cosmetic industry integrates in its products active ingredients of vegetal origin. For this purpose, plant extracts are prepared and their content must be characterized to check their conformity with safety regulations. Many plant extracts contain a high proportion of high-boiling-point solvents that may conflict with analytical protocols. Extract analysis by fractionation and subsequent 13C NMR analysis required a new solvent signal suppression technique to provide better analytical data.
