Simple extraction method of green crude from natural blue-green microalgae by dimethyl ether

By using dimethyl ether as extractant, the green crude was successfully extracted from high-moisture natural blue-green microalgae (91.0% of water content) with a high extraction capacity at 40.1% of dry weight of the microalgae. Compared with previous methods, this method combined drying, cell description, and solvent extraction in one step.
