    United States Patent 6365757
    Process for the production of a compound (&plus ) catechin penta acetate useful as a precursor for the production of (&plus ) catechin[Reference: WebLink]

    METHODS AND RESULTS:
    This invention relates to a process for the production of a compound (+) catechin pentaacetate of formula I from Taxus wallichiana tissue cultures which comprises : (a) inoculation of explants on different media compositions supplemented with combinations of auxins (1-5 mg/l) and cytokinins (0.1-1.0 mg/l); (b) incubation of the cultures under continuous light or dark conditions for 4-6 weeks for callus cultures followed by subculturing at 4-6 weeks intervals; (c) harvesting of the calli at different growth phases ranging from 12-36 months; (d) extraction of fresh pulverized calli with polar solvents at room temperature; (e) evaporating the solvent to give a residue; and partitioning of the residue between water and chlorinated solvents and evaporating the solvent to a semisolid mass; (f) subjecting the resultant mass to column chromatography over suitable adsorbent and (g) eluting with organic solvent/mixtures of organic solvents to get (+) catechin pentaacetate.
