摘要

Isolation procedure of giberelines of the lithium of stimulated crystalization of ethyl acetate. Consists of the following stages: 1. Dilute highly viscous soldier liquor with mother solvent in a proportion of 1: 4 to 1:15. 2. Separate precipitated impurities. 3. Extract the clear solution with aqueous solution of alkaline compounds. 4. Transfer the giberelines in the form of your salts to the aqueous solution. 5. Acidify this solution under continuous mixing at ph 3.5-1.5. 6. Separate the resinous compounds. 7. Insulate the giberelines of the residual aqueous solution through extraction with dissolved ethyl acetate in water. 8. Recycle the water residue to the residual fermentation body.
