A method for extracting active ingredient(s) from a raw material to be extracted is provided. The method comprises the following steps: (1) mixing a raw material to be extracted with an aqueous solvent to provide a mixture； (2) conducting a homogenization to the mixture to obtain a first extract with active ingredient(s)； and (3) conducting a high pressure homogenizationto the first extract to obtain a second extract with active ingredient(s), wherein the homogenization in step (2) is conducted at a temperature ranging from normal temperature to 100℃.本發明提供一種自待萃物萃取活性成分的方法，包含如下步驟：（1）將待萃物與水性溶劑混合，以提供一混合物；（2）對該混合物進行均質處理，以獲得含活性成分之第一萃取液；以及（3）對該第一萃取液進行高壓均質處理，以獲得含活性成分之第二萃取液，其中，該步驟（2）之均質處理係於常溫至100℃之溫度下進行。
