The present invention relates to the technical field of medicine, and relates specifically to a method for dissolving a flavonoid compound, a carbon glycoside compound, or a stilbene compound and a method for preparing an injection or a powder for injection. The method: the flavonoid compound, the carbon glycoside compound, or the stilbene compound is mixed with a solubilizer to acquire a reactant; when water for injection is heated and stirred in a vacuum, the reactant is added under the protection of nitrogen or argon to acquire a product. The dissolution speed of the method is fast, redissolution tests show that a freeze-dried powder that is acquired when a water-soluble medicament acquired is freeze-dried can dissolve completely in just five seconds, a significant increase in redissolution speed compared with a control group; also, the stability is great, and a medicinal requirement for clinical emergencies is satisfied.
