摘　　要：目的探索适宜的干燥方法,为草果药材的加工、提高药材品质奠定基础。方法采用两段式干燥处理(第一阶段:40℃、60℃烘烤,或微波低火干燥;第二阶段:25℃烘干)草果新鲜果实,比较分析种子挥发油含量、果实失水率的相应变化。结果种子挥发油含量在不同干燥方法之间有极显著差异(df=5,F=64.072,P=0.000)。控制居群影响,种子挥发油含量与不同干燥方法之间有极显著的相关性(df=178,R=0.266,P=0.005)。结论本研究中,40℃烘烤5 h后,再25℃烘干的处理,种子挥发油含量最高。第一阶段干燥处理的失水率是一个重要的考察指标,可能影响草果药材品质。Objective To explore the suitable drying methods,laying a foundation for the processing and quality guarantee of the medicinal materials of Amomum tsaoko.Methods Drying the fresh fruits of A.tsaoko by the two-stage processing(The first stage:40℃,60℃baking individually,or low-intensity microwave drying.The second stage:25℃baking),then a comparative analysis was performed by investigating the variation of the seed essential oil content,and water loss rate among the different drying methods.Results There were greatly significant differences among the different drying methods in the seed essential oil content(df=5,F=64.072,P=0.000),and greatly significant correlation between them(df=178,R=0.266,P=0.005)by controlling the influence of population.Conclusion In the present study,the baking at 40℃for 5 h and then drying at 25℃could gain the highest content of volatile oil from the seeds than the other processing.The water loss rate after the first-stage processing was an important index of evaluation,which would influence on the medicinal materials quality of A.tsaoko.
