Abstract
1,228,888. Recovery of gibberellins. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUT FITOPATOLOGII. 8 Oct., 1968, No. 47643/68. Heading C2C. A giberellin-containing precipitate is obtained from a microbial culture broth by addition of an iron salt to the culture filtrate at a pH of 2À5- 4À5. The filtrate may be that obtained by culturing Fusarium moniliforme Sheldon and separating the mycelium from the broth, optionally after addition of barium chloride which precipitates some impurities. The preferred iron salt is ferric or ferrous chloride which may be added to the filtrate together with NaCl The pH is adjusted to 2À5-4À5 by addition of, e.g., sodium or ammonium hydroxide. A precipitate comprising gibberellins, iron salt and impurities is obtained which is filtered off and dried. Crystalline gibberellin may be obtained from the crude mixture by treatment with an aqueous alkaline solution, separation of any insoluble resin, extraction of the aqueous solution with an organic solvent, e.g. ethyl acetate, and evaporation of this solvent.
