摘　　要：采用单因素试验和正交试验,以灵芝多糖得率为指标,探讨了射频技术在提取灵芝多糖中的应用。结果表明,射频技术提取法的最适工艺条件为水中浸润60 min,射频(27MHz)提取温度(80±2)℃,时间3min,液料比60∶1。与热水提取法、微波提取法、超声波提取法相比,射频技术提取法具有高效、省时的特点。By the single factor experiment and the orthogonal experiment and using polysaccharides rate as the index,radiofrequency（RF） technology was used to extract polysaccharides of Ganoderma lucidum in this paper.The optimizing conditions were presoak time 60 min,RF（27MHz） temperature（80±2）℃,RF time 3 minutes,adding 60 times tap water.Compared with water extraction,microwave-assisted extraction and ultrasound extraction,radio-frequency technology was characteristic of short time and high quality.
