Abstract
Pressurized liquid extraction of apigenin from Scutellaria barbata was compared to the traditional Soxhlet extraction using methanol. The conditions for pressurized liquid extraction were as follows: the extraction solvent was 100% ethanol, 50% aq ethanol or water; the extraction temperature was 120 degrees C; static extraction time was 5 min. For the traditional Soxhlet extraction, the sample was boiled at 50 degrees C for three hours. According to calculations by regression parameters using HPLC analysis, the extraction yields of apigenin were 1.25 mg/g by pressurized liquid extraction (extraction solvent, 100% ethanol; temperature, 120 degrees C; static extraction time, 5 min), 0.32 mg/g by pressurized liquid extraction (extraction solvent, 50% aq ethanol; temperature, 120 degrees C; static extraction time, 20 min) and 0.88 mg/g by Soxhlet extraction using methanol. Pressurized liquid extraction using 100% ethanol yielded 74.4 % higher apigenin than using 50% aq ethanol and using. 100% ethanol yielded 29.6% higher apigenin than using the Soxhlet extraction technique.
