【摘要】 目的研究药材粉碎度、加水量、提取时间对莪术挥发油提出率的影响,研究挥发油提出速度的影响因素。方法以单因素对比实验,考察加水量与粉碎度对挥发油提出率的影响;以挥发油提出率为指标,用L9(34)正交实验,优化提取条件,考察药材粉碎度、加水量、提取时间对挥发油提出率的影响;以单因素对比实验,探讨挥发油提出速度的影响因素。结果药材粉碎度、加水量、提取时间对挥发油提出率均有显著性影响,最佳提取工艺条件为:莪术粉碎度为40~80目,药∶水为1∶40,提取时间为2 h。结论随药材粉碎度、加水量、提取时间的增加,挥发油提出率增加;出油速度与药材的粉碎度、加水量均成正相关关系。更多还原

【Abstract】 Objective To study the effect of grinding degree of material,quantity of water and distillation time upon volatile oil yield.To sutdy experimental parameters on extraction rate.Methods The experiment was carried out with L9(34)orthogonal design,by determining the volatile oil yield,to study the effect of grinding degree of material,quantity of water and distillation time upon volatile oil yield.Experimental parameters on extraction rate was studied with contrast test.Results Grinding degree of material,quantity of water and extraction time had remarkable effect upon volatile oil yield.The optimum parameters were as follows:grinding degree of Rhizoma Curcumea trumeric was 40～80-mesh powder,ratio of material and water was 1∶40,distillation time was 2 h.Conclusion Volatile oil yield increases as the grinding degree of material,quantity of water for distillation time increase.Grinding degree of material and quantity of water has positive effect upon extraction rate.更多还原
