The invention relates to a folium turpiniae extract. The folium turpiniae extract is extracted through the following methods: (1) carrying out enzymolysis on an aqueous solution containing folium turpiniae powder by using cellulase in the presence of ultrasonic waves, centrifuging an enzymolysis solution, and then, collecting supernatant; (2) concentrating the supernatant, then, adjusting the concentration of ethanol in the concentrate to 75% to 85%, carrying out low-temperature standing, carrying out centrifuging to collect secondary supernatant, and carrying out concentrating until ethanol in the secondary supernatant is removed, thereby obtaining the folium turpiniae extract. According to the folium turpiniae extract provided by the invention, the extraction method is simple, and the cost is low; the folium turpiniae extract has a blood fat reducing effect and can be prepared into pharmaceutical compositions for reducing blood fat, so that the application prospect is broad.
