1. a kind of method that luteole is prepared from capsanthin, it is characterised in that comprise the following steps that:

  • (1) rough segmentation:

    Using capsanthin as raw material, using silica gel column chromatography, pass through the corn in gradient elution initial gross separation capsanthinFlavine;

    (2) saponification:

    Luteole after rough segmentation is added into 1-5 times of alcohol aqueous slkali and carries out saponification process, saponification temperature is 50-70DEG C, saponification time is the recycling design that is concentrated under reduced pressure after the completion of 4-6h, saponification;

    (3) extract:

    Luteole after saponification is dissolved with lipophylic organic solvents, with pure water cyclic washing 3 times, is concentrated under reduced pressureRecycling design, obtains luteole crude product;

    (4) segment:

    Silica gel column chromatography separating corn flavine crude product is reused, gradient elution is the maize for obtaining high-purityElement.
