Abstract

PURPOSE: To separate a polymeric ketone, esp. bombiprenone useful as a raw material of pharmaceutical, easily and conveniently from plants containg a long chain polyisoprenoid compound, using n-hexane as a solvent which is selective to bombiprenone.
CONSTITUTION: Esp. leaves of a plant containing a long chain polyisoprenoid compound, e.g. tabacco, mulberry etc., are extracted with an ordinary lipophilic solvent, e.g. acetone. The extracted lipophilic component of the leaf is then saponified with an alkali. By this treatment most of the non-sisprenoid compounds are saponified and transferred to the aqueous layer. After the separation of the aqueous layer, the substances which are not saponified are treated with n-hexane to extract bonbiprenone selectively into the above layer. The impurities extracted together are separaed by crystallization and then the solvent is removed by conventional method, to give a polymeric ketone, esp. bombiprenone, easily and conveniently.
