Optimization of ultrasound-assisted enzymatic pretreatment for enhanced extraction of baicalein and wogonin from Scutellaria baicalensis roots.
It is of great theoretical interest and industrial significance to improve the extraction efficiency of baicalein and wogonin from Scutellaria baicalensis roots because of their high pharmacological activities. The present study was aimed to establish the optimized ultrasound-assisted enzymatic pretreatment (UAEP) process by which ultrasound irradiation and the exogenous enzyme were simultaneously applied to efficiently transform baicalin and wogonoside into baicalein and wogonin, enhancing their extraction efficiency. Single-factor experiment and Box-Behnken design were used to optimize the main UAEP conditions to maximize the total extraction yield of baicalein and wogonin. The optimized UAEP conditions were cellulase concentration of 1.1%, pH of 5.5, UAEP temperature of 56.5 °C, UAEP time of 39.4 min, and ultrasonic power of 200 W with the total extraction yield of 82.51 ± 0.85 mg/g DW. The comparison of the established technique with the reference method based on the enzymatic pretreatment revealed that the productive efficiency was significantly improved with the transformation rates nearly doubled. These results suggest that the optimized UAEP process has the potential to be applied for the green, simple, and efficient extraction of baicalein and wogonin in the pharmaceutical and food industry.

[Enzymatic extraction of baicalein and wogonin from radix scutellariae].
The optimum enzymatic extraction of baicalein and wogonin from Radix scutellariae were determined.. HPLC method was used to determine the content of baicalein and wogoinin from Radix Scutellariae, 5 factors were studied on enznmalic extraction of celluase.. The optimum enzymatic extraction of celluase were determined as follows enzyme 20U for Ig material, pH 4.8, buffer to raw material ratio20, temperature 50 degrees C, and reaction time 8 h.. Compared with the traditional water extraction, the extraction yield of baicalein and wogonin increase 5 and 4 times.
