Objective:
The optimum enzymatic extraction of baicalein and wogonin from Radix scutellariae were determined.
Methods:
HPLC method was used to determine the content of baicalein and wogoinin from Radix Scutellariae, 5 factors were studied on enznmalic extraction of celluase.
Results:
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.
Conclusion:
Compared with the traditional water extraction, the extraction yield of baicalein and wogonin increase 5 and 4 times.
