| Abstract: | A microwave-assisted extraction procedure was developed for transhinone Ⅰ, transhinone ⅡA and cryptotranshinone in Chinese herbal medicine Salvia mltiorrhiza Bunge, using an obturated microwave-assisted extraction device with a pressure controlling part. The effects of the solvent consistence, solid/liquid ratio, the microwave radiation time and sample particles on the leached output was studied. Compared with Soxhlet extraction and ultrasonic extraction, microwave-assisted extraction is more efficient. |
