Extraction method of phellinus igniarius triterpenoids

The method comprises the following steps: preparation of phellinus igniarius powder, low-temperature freeze-dried powder crushing, extraction, enzymolysis in a high-voltage pulse alternating electric field, primary rotary evaporation, extraction and secondary rotary evaporation, and finally, the high-purity phellinus igniarius triterpenoids are obtained. According to the method, the phellinus igniarius triterpenoids are extracted to the maximum extent through two times of ethanol ultrasonic extraction, and then the high-purity phellinus igniarius triterpenoids are obtained through combined extraction of high-voltage pulsed electric field treatment and an enzymolysis method and secondary rotary evaporation. The method provided by the invention is high in extraction rate, short in extraction time and convenient to operate, and the obtained phellinus igniarius triterpenoids are high in purity and have great medicinal value. 本发明公开了一种桑黄三萜类化合物的提取方法，包括以下步骤：桑黄粉的制备，低温冻干粉碎、浸提、高压脉冲交变电场中酶解、一次旋转蒸发、萃取、二次旋转蒸发，最终得到高纯度的桑黄三萜类化
