摘　　要：沙蒿籽胶是一种天然的增稠剂,利用醇沉法提取沙蒿籽胶,以提取率为考察指标,得出醇沉法提取沙蒿籽胶的最佳工艺。采用单因素试验分析乙醇体积浓度、p H、温度、时间对醇沉法提取沙蒿籽胶的影响,并通过正交试验确定了最佳工艺条件为:乙醇体积浓度50%、p H值4.0、温度15℃、时间3.0 h次。在此工艺条件下,沙蒿籽胶的提取率达17.74%。Artemisiasphaerocephalakrasch gum is a natural thickener,alcohol sedimentation was were used to extractartemisiasphaerocephalakrasch gum, which can drawa conclution of alcohol sedimentation are optimal extracting conditions. By single factor experiment of ethanol concentration, p H,standing temperature, standing time, to discuss the infuence of artemisiasphaerocephalakrasch extraction of the gum. The optimal extracting conditions of artemisiasphaerocephalakrasch gum by water extraction are revealed as follows： ethanol concentration60%, p H4, standing temperature 15 ℃, standing time 3 h and extracting rate 17.74%.
