A method for extracting minor fatty compounds, particularly steroids, from biological matter by means of cyclodextrin. According to the method, the cyclodextrin is stirred into said biological matter in a water-containing reaction medium to allow the formation of inclusion complexes between the cyclodextrin and the minor fatty compounds, whereafter said complexes are separated from said matter, the amount of water present in the reaction medium being lower than 100 % wt. in relation to the dry matter to be treated. The temperature of the reaction medium and the amount of water present therein are such that the cyclodextrin is partially undissolved. |
