摘　　要：该文通过单因素试验,研究变温压差膨化温度、膨化压力、膨化时间、真空干燥温度和真空干燥时间对栀子中栀子苷提取率的影响。在单因素试验基础上,选择膨化温度、真空干燥温度和真空干燥时间3个影响明显的因素作为变量,进行响应面优化试验。最终确定变温压差膨化处理栀子苷的最优提取工艺参数为膨化温度73℃、膨化压力0.3 MPa、膨化时间2 min、真空干燥温度68℃、真空干燥时间70 min。该条件下栀子苷提取率达(7.38±0.59)%。The effects of puffing temperature,puffing pressure,puffing time,vacuum drying temperature,and vacuum drying time under variable temperature and pressure conditions on the extraction yield of geniposide from Fructus gardeniae were studied by single-factor experiment.On the basis of the single-factor experiment,three significant factors,namely puffing temperature,vacuum drying temperature,and vacuum drying time were selected as variables for the response surface optimization experiment.The optimum extraction conditions of geniposide by variable-temperature and pressure puffing method were determined as follows:puffing temperature at 73℃,puffing pressure of 0.3 MPa,puffing time of 2 min,vacuum drying temperature at 68℃,and vacuum drying time of 70 min.The extraction yield of gardenoside under this condition was(7.38±0.59)%.
