The invention discloses a method for preparing a rose extracting solution, rose water taking the rose extracting solution as an active ingredient, and a preparation method of the rose water. The rose extracting solution is prepared by the following steps: taking rose as a raw material, performing water leaching distillation, collecting a gas phase part, condensing, concentrating and sterilizing. The method for preparing the rose extracting solution comprises the following steps: treating the raw materials, performing water leaching distillation and sterilizing. The rose water which takes the rose extracting solution as the active ingredient comprises 2-5 weight percent of rose extracting solution, 0.01-0.03 weight percent of flavoring agent and the balance of purified water; and the method for preparing the rose water which takes the rose extracting solution as the active ingredient comprises the steps of adding the rose extracting solution into water to be prepared according to a formula weight ratio, uniformly mixing, and sterilizing to obtain target rose water. By the adoption of the water leaching distillation, comprehensiveness of contained substances is guaranteed, and components of aroma volatile oil are kept; and moreover, the rose water is clean in aroma and elegant in taste, contributes to relieving the emotion, improving the internal secretion and relieving the feeling of fatigue without adding any coloring matter and preservative, is safe to drink, and is safe and reliable.
