The invention relates to a method for extracting unsaturated fatty acids from eucalyptus leaves. An organic solvent is used for extraction. Unsaturated fatty acid crude extracts are obtained by low-temperature crystallization treatment after dissolution, and more than 7 percent of unsaturated fatty acid component is obtained by CO2 critical extraction. The extraction method is simple, convenient, low in cost, stable in process and high in extraction efficiency. The unsaturated fatty acids in the eucalyptus leaves cotain polyunsaturated fatty acids such as linoleic acids and linolenic acids, are natural extracts, have the effects of resisting bacteria, resisting oxidation, depressing blood fat, lowering cholesterol, improving memory, suppressing tumors and the like, and can be widely applied to the fields of feeds, cosmetics, foods, biochemical engineering, even medicine and the like.

The invention relates to odorless high-strength regenerated rubber and a preparation method thereof. The regenerated rubber is prepared from waste rubber powder and auxiliary materials according to the weight ratio of (12-15):(3-4.5). The auxiliary materials are composed of the following raw materials in parts by weight: 10-20 parts of paraffin oil, 2-5 parts of linolenic acid, 5-8 parts of rosin,1-2 parts of an aluminate coupling agent, and 4-6 parts of a regenerant. The regeneration reaction is mild and environmentally friendly. The prepared regenerated rubber has no strong irritating odor,and the tensile strength, elongation at break and other parameters of the regenerated rubber are better.
