Experimental Study Extraction Oil from Francoeuria Undulata Using Supercritical Carbon Dioxide

Supercritical fluid extraction method is a replacement of conventional methods such as organic solvent
extraction with hex
temperature (35, 45, 55 °C), pressure (150, 175, 200 bar) a
extraction yield in conditions of pressu
ane and mechanical pressing. Because in this method the operation temperature is low and
the solvent does not remain in the final product. In this study, the effect of changing three parameters of
nd particle size (0.074, 0.149, 0.210 mm) on the
extracted oil yield of the medicinal plant of Francoeuria undula using supercritical carbon dioxide was
investigated. The results of the experiments showed that the extraction yield was increased by particle size
reduction and increased pressure. Temperature up to 45 ºC has a positive impact on the extraction efficiency.
However, increased efficiency was observed with increasing temperature more than of 45 °C. The best
re was 200 bar, temperature 45 °C and particle size of 0.074 mm.
