Study on Extraction Technology of Curcumin and Turmeric Oil from Curcuma longa L.
Curcumin and turmeric oil are essential bioactive components in ginger plants.Curcumin has various bioactive effects such as scavenging free radicals in body and inhibiting the growth of tumor cells,while turmeric oil has bioactive effects such as antibiosis and liver protection.In order to improve the bioavailability of curcumin,improve the texture and taste of turmeric oil,develop new products of curcumin and turmeric oil,and increase the economic value of curcumin and turmeric oil,in this study,single factor test,Plackett-Burman(PB)test and orthogonal test are used to study the extraction technology of curcumin and and turmeric oil from Curcuma longa L..The results indicate that the optimal extraction technology of curcumin and turmeric oil are ethanol concentration of 60％,solid-liquid ratio of 1∶15,ultrasonic power of 210 W,ultrasonic time of 40 min and ultrasonic temperature of 50 ℃.
