Objective : To extract artemisinin from Artemisia annua by microwave-assisted extraction (MAE) using a novel separation method. METHODS: Ethanol, chloroform, cyclohexane, n-hexane, petroleum ether at 30°C to 60°C, petroleum ether at 60°C to 90°C, solvent oil No. 120 and solvent oil No. 6 were selected as extraction media. Microwave-assisted extraction experiments were performed in an intermittent microwave-assisted extraction device. Results: The effect of artemisinin yield on microwave irradiation time, solvent ratio, material grinding degree and other technological conditions. The best solvent for evaluation was #6 extraction solvent oil. Conclusion :Microwave-assisted extraction is suitable for extracting artemisinin from Artemisia annua
