干燥和储存方式对广藿香有效成分的影响

Effect of Drying and Storage Methods on the Active Ingredients of Pogostemon cablin

[目的]研究不同干燥、储存方式和储存时间对广藿香有效成分含量的影响。[方法]以发汗、阴干、晒干和烘干法作为干燥方式,常规、低温和气调储存作为储存方式,储存180和360 d后的挥发油、广藿香醇和广藿香酮含量作为衡量标准。[结果]烘干和晒干法容易造成挥发油的损失,酮醇总含量较低;发汗法有利于有效成分保留。常规储存180 d后广藿香药材出现发霉、虫蛀、褐变以及有效成分降低的现象。气调储存广藿香药材变化较小。[结论]发汗法和气调储存可作为广藿香产地初加工方法及储存方式。

[Qbjective]To study the effect of different drying,storage methods and storage time on the content of active ingredients in Pogostemon cablin.[Method]The methods of sweating,drying in the shade,sun-drying and drying were used as drying methods,and the methods of conventional,low temperature and modified atmosphere storage were used as storage methods,volatile oil,patchouli alcohol and patchouli ketone were measured after 180 and 360 days of storage.[Result]Drying and sun-drying methods were lost of volatile oil,and the total content of ketone and alcohol was low.Sweating method was beneficial for retaining active ingredients.After storage for 180 days,the medicinal materials of Pogostemon cablin appeared mouldy,moth-eaten,browning and the effective components decreased.Controlled atmosphere storage of Pogostemon cablin changed little.[Conclusion]Sweating method and modified atmosphere storage can be used as the primary processing and storage method of Pogostemon cablin.
