Abstract: The ultrasonic extraction technique was used to extract shikonin and its derivatives from Arnebia euchroma roots. The effects of ultrasonic power, temperature, extracting time, herbal powder size and liquid-to-solid ratio on the extraction of shikonin were studied. The ultrasonic wave extraction results showed that the optimal extraction conditions were as follows: the powder size of Arnebia euchroma roots was 80 mesh (180 mm), liquid-to-solid ratio 12 mg/L, temperature 50℃, extraction time 25 min and ultrasonic power 1800 W.
Key words: ultrasonic extraction, Arnebia euchroma (Royle) Johnst., shikonin, derivatives
