Cuticular waxes from potato leaves - evaluation of extraction methods



The optimal times for the extraction of cuticular waxes with dichloromethan were estabilished for three classess of compounds, namely 40 sec for alcohol and fatty acids and 40 sec for alkanes, which is sufficient to isolate at least ca.90% of wax components. A two-step extraction using two consecutive portions of solvent ensured better recovery (ca.94%) than a one-step procedure (49-60%).
