Methods: Using microwave extraction technology, we studied the effects of ethanol concentration, microwave power, extraction time, extraction temperature on extraction process of gypsogenin-3-O-glucuronide. Results: Linear range of gypsogenin-3-O-glucuronide was 0.024～0.120 mg, and the average recovery rate was 100.2％. The best extraction process was to extract 12 minutes with 35％ ethanol, 65 ℃ and 400 w. The average extraction rate was 83.4％. Conclusion: The microwave extraction method was reliable and stable to extract the gypsogenin-3-O-glucuronide from momordica cochinchinensis. At the same time, this optimized extraction process was simple, energy conversation, time-saving and feasible.
