Abstract
Samples of the microalga Botryococcus braunii were submitted to superc ritical fluid extraction with carbon dioxide at 40-degrees-C and press ures of 12.5, 20.0 and 30.0 MPa. The extraction yield and the fraction of the hydrocarbons in the extracts both increased with pressure and at 30 MPa these compounds were obtained rapidly. This behaviour is ass ociated with the localization of the hydrocarbons outside the cell wal l. In the extracts, which are fluid, golden and limpid, chlorophyll an d phospholipids were not detected.
