1. A process for extracting lipids from Mortierella genus fungi, which comprises the steps of:
- (a) heating Mortierella genus fungi cells and grinding the same by applying a mechanical force thereto or grinding the same by applying a mechanical force thereto in an alcoholic solvent; and
(b) extracting the lipids from said Mortierella genus fungi cells thus ground with a solvent selected from the group consisting of a solvent in a supercritical state, a solvent mixture of said solvent in a supercritical state and a lower aliphatic alcohol and a solvent mixture of said solvent in a supercritical state and a lower saturated aliphatic hydrocarbon.

Abstract
Lipids containing gamma-linolenic acid are extracted from cells of Mortierella genus fungi by first grinding the cells in the presence or absence of a hot alcoholic solvent, and then extracting the alcohol-treated ground cells with a solvent in a supercritical state, or a mixture of a solvent in a supercritical state with a lower aliphatic alcohol or a lower aliphatic hydrocarbon.
