The non-extraction method is fast as roots are directly depolymerized using acidic transmethylation. However, suberin aliphatic components are isolated together with all the other acyl chains making up the lipids ( e.g., membranes) present in roots. For the solvent-extraction method, roots are first delipidated before transmethylation.
Three extraction methods are described: Ultrasound-Assisted Extraction 60 (UAE), Microwave-Assisted Extraction (MAE) and Pressurized Liquid Extraction 61 (PLE).
