The invention discloses a
viburnum sargentii
branch and leaf
lignan, an extraction method and application. The extraction method comprises the steps of smashing dried
viburnum sargentii branches and leaves, and the like; using a constant-temperature ultrasonic instrument for suspending an extract with
warm water, extracting, and decompress concentrating to obtain an extract; dissolving the extract at a cholorform part in
methanol, eluting to remove
chlorophyll, carrying out
chromatography and purification to obtain 5 different compounds. A
monomer lignan obtained through the invention has the purity achieving 96 percent to 99 percent, can be subjected to goal-oriented structural modification, and is applied in pharmaceutical synthesis so as to obtain pharmaceutical molecules with better activity; 5 lignans are firstly extracted from
viburnum sargentii , so that an approach for obtaining such natural active ingredients is wider. The extraction method provided by the invention is simple and convenient, easy to separate and recover an
organic solvent mixture, less in emission, and suitable for modern fine industrial production. The invention adopts a latest SBC MCI GEL reversion phase
chromatography filler, so that the removal rate of
chlorophyll is improved from 60 percent to 70 percent to 97 percent to 100 percent. The invention discloses anti-atherosclerosis application of the
lignan monomer.
