Abstract
A simple, rapid and environmentally friendly method named effervescence-assisted matrix solid-phase dispersion (EA-MSPD) was investigated for the extraction of four coumarins (esculin, esculetin, fraxin and fraxetin) from Crotex fraxini (C. fraxini). In this study, an effervescent tablet containing carbon dioxide sources (100 mg sodium bicarbonate and 200 mg sodium dihydrogenphosphate) and an adsorbent (25 mg benzo-15-crown-5) was prepared. The...
