Abstract

The invention discloses a method for extracting momordica grosvenori fruit, which relates to the technical field of plant extraction, and solves the problem that the momordica grosvenori fruit easilyover-damages the cell wall during the extraction process to cause poor overall application effect. The method comprises the following steps: step one, freeze pulverization; step two, petroleum ether extraction treatment; step three, drying treatment; step four, microwave reflux extraction; and step five, filtration and concentration. In the method for extracting the momordica grosvenori fruit, byinfiltrating the raw material of the momordica grosvenori fruit with water, the freezing treatment is performed, then pulverizing is carried out, the damage of the cell wall of the momordica grosvenori fruit can be reduced, which is beneficial to avoid the introduction of impurities and the loss of active ingredients, so that the method for extracting the momordica grosvenori fruit has the good application effect as a whole.
