摘　　要：采用不同干燥方式(自然晒干、60℃烘干、80℃烘干、105℃烘干、冻干)对茯苓(Poria cocos)鲜品进行干燥,测定干燥后的茯苓三萜类及茯苓酸含量,比较不同干燥方式对其三萜类及茯苓酸含量的影响。结果表明,茯苓三萜类及茯苓酸含量均为冻干>105℃烘干>80℃烘干>60℃烘干>自然晒干,冻干工艺下茯苓三萜及茯苓酸含量分别高达8.95%、6.89%,自然晒干下的茯苓三萜类及茯苓酸含量均最低。确定了茯苓药材的最佳干燥方式,为茯苓药材后期加工工艺的选用提供参考。The fresh Poria cocos were dried by different drying methods(natural drying,drying at 60℃,drying at 80℃,drying at 105℃and freeze drying).The contents of triterpenes and pachymic acid of dried Poria cocos were determined,and the effects of dif-ferent drying methods on the contents of triterpenes and pachymic acid were compared.The results showed that the contents of triter-penes and pachymic acid in Poria cocos were freeze drying>drying at 105℃>drying at 80℃>drying at 60℃>natural drying.Un-der the freeze drying process,the triterpenes and pachymic acid contents of Poria cocos were up to 8.95%and 6.89%,respectively,and the triterpenoids and pachymic acid contents of natural drying Poria cocos were the lowest.The best drying method of Poria cocos was determined to provide reference for the selection of the post-processing technology of Poria cocos.
