Abstract

IN recent years ultrasonic energy has been used in the extraction of various materials from plants, animals, and micro-organisms for biochemical analysis1. The application of ultrasound has proved advantageous for the isolation of enzymes, nucleic acids, and other heat-labile substances from cells and tissues. Moreover, ultrasonic energy has been used widely for various industrial applications to facilitate the extraction of commercially important substances2. The increasing use of ultrasonic instruments in extraction processes is based on the observations that: (1) disruption of cells is rapid; (2) the extraction process is accelerated; (3) the yield of extract usually is increased; (4) the use of ultrasonic energy permits the extraction of certain materials otherwise not readily obtainable.
