Extraction of atropine by ultrasounds in different solvent systems

The use of ultrasounds for extraction of atropine from Egyptian henbane (Hyoscyamus muticus) has been studied. The kinetic of extraction using various solvent systems was carried out. The results obtained have shown that the most efficient system of solvents was CH3OH/CH3CN (80:20). The amount of atropine was calculated by HPLC.
