Abstract:

The microwave-assisted extraction of seed oil from Salicornia bigenlovii Torr. using petroleum ether as the
extraction solvent was optimized by response surface methodology. The extraction yield of seed oil was investigated with
respect to extraction temperature, extraction time, solid-to-liquid ratio, and microwave power. The results showed that the
optimal extraction conditions for Salicornia bigenlovii Torr. seed oil were as follows: temperature, 55 ℃; extraction time,
5 min; solid-to-liquid ratio, 1:10 (g/mL); and microwave power, 700 W. Under these optimal conditions, the extraction yield
of Salicornia bigenlovii Torr. seed oil was 32.58%, a 0.15% increase over that obtained by traditional Soxhlet extraction.
Moreover, the extraction time was only 1.39% of that required by Soxhlet extraction.
