摘　　要：采用超高压技术提取灵芝孢子粉多糖,通用正交试验法,以多糖得率为指标,考察料液比、温度、压力、保压时间等因素对多糖提取的影响,并与水浸提法比较。超高压提取灵芝多糖最优工艺条件为:压力为400MPa,温度为50℃,固(g)液(mL)比1:40,保压时间应低于6min;提取得率为2.762%,高出水浸提提取37.1%,超高压提取具有得率高,提取温度低、提取时间短、节能等优点,为灵芝多糖的提取提供了一种新技术。Extraction of polysaccharide from ganoderma lucidum spore using ultra high pressure （UHP） was studied. The experiment was optimized with the orthogonal test design. The optimum extraction conditions were pressure 400MPa, temperature 50℃, ratio of Ganoderma Lucidum（g） to solvent（ml） 1：40, and extraction time 〈6 min, under which the yield ofpolysaccharide reached 2.762%, which was 37.1% higher than that with the water extraction. This method had many advantages, such as higher extraction efficiency, lower energy consumption, and shorter extraction time, providing a new process for the exlraction of polysaccharide from Ganoderma lucidum.
