Zusammenfassung:	The invention relates to a preparation method of a plant mothproofing agent for wool products. The preparation method comprises the following steps of: (1) taking radix stemonae of plant, crushing the radix stemonae and extracting extract liquor containing mothproofing components with ethanol water; (2) filtering the extract liquor with a microfiltration membrane, and removing impurities to obtain refined solution; (3) evaporating and concentrating to obtain concentrated solution; (4) carrying out spray drying on the concentrated solution to prepare the powdery plant mothproofing agent. The invention is simple, has low cost and wide raw material source and is suitable for industrial production. The obtained mothproofing agent is mothproof effectively, is nonhazardous to human body and hasno pollution to the environment. When being applied to the wool products, the plant mothproofing agnet can be stained with dye simultaneously to obtain products with different colors.
