Abstract
A method for producing galanthamine using a plant, includes (a) performing a thermal treatment on a living plant to induce accumulation of galanthamine therein, wherein the living plant is a plant belonging to the family Amaryllidaceae; and (b) placing the living plant in a medium and performing an electrical stimulation treatment on the living plant to release the galanthamine from the living plant to the medium.
Claims23
A method for producing galanthamine using a plant, comprising:
- (a) performing a thermal treatment on a whole living plant or a part of a whole living plant which remains in the whole living plant to induce accumulation of galanthamine therein, wherein the whole living plant is a plant belonging to the family Amaryllidaceae, and wherein the temperature of the thermal treatment is 40° C. to 60° C.;
- (b) placing the treated whole living plant or the whole living plant comprising the treated part in a medium for electrical stimulation treatment and performing an electrical stimulation treatment on the whole living plant to release the galanthamine from the whole living plant into the medium, wherein a voltage applied by the electrical stimulation is 3 V to 40 V and time required for the electrical stimulation treatment is 1 minute to 30 minutes;
- and
- (c) placing the treated whole living plant or the whole living plant comprising the treated part in a repair medium to repair the whole living plant after step (b).
