Abstract: A method for extracting flavone aglycones in Chrysanthemum morifolium is provided. The method includes: (a) immersing a Chrysanthemum morifolium raw material in water or an aqueous solution to perform an immersion procedure for 3.5 hours or more to obtain an immersion sample; and (b) adding an extraction solvent to the immersion sample to perform an extraction procedure 5-60 minutes to obtain an extract. The Chrysanthemum morifolium raw material includes at least one of the following parts of Chrysanthemum morifolium: whole plant, roots, stems, leaves and flowers.

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.

Abstract: A method for inducing plants to increase their flavonoid compound content, includes performing an induction culture on a young shoot or an adult of a living plant, wherein flavonoid compound content of the young shoot or the adult of the living plant which has been subjected to the induction culture is higher than that of a young shoot or an adult of a living plant which is not subjected to the induction culture. Moreover, the induction culture includes a metal ion stimulation procedure comprising culturing the young shoot or the adult of the living plant in a culture environment with metal ion stimulation, wherein the culture environment with metal ion stimulation contains a metal ion used for stimulating the living plant, and the concentration of the metal ion used for stimulating the living plant is 5 ?M-50 mM.
