不同干燥方法对栀子药材中两种化学成分含量的影响

Effects of different drying methods on the content of two components in Fructus Gardeniae

目的评价不同干燥方法对生药栀子中两种主要成分含量的影响。方法采用100℃烘干、50℃烘干、冷冻干燥、蒸后烘干、减压干燥、微波干燥6种方法处理栀子药材,采用RP-HPLC法测定栀子中两种主要成分栀子苷和西红花苷-1。结果定量分析了6种干燥方法炮制的栀子药材中两种主要成分的含量。结论不同干燥方法对栀子药材中栀子苷和西红花苷-1的含量有一定影响,50℃烘干对两类成分的保存均具有较好的效果,冷冻干燥、减压干燥、100℃烘干效果一般,蒸后烘干和微波干燥对栀子苷的保存效果较好。

OBJECTIVE To evaluate the effects of different drying methods on the content of two components in Fructus Gardeniae. METHODS Fructus Gardeniae was processed by six drying methods including oven drying under 100℃ , oven drying under 50℃, freeze - drying, oven drying after steaming, vaceum drying, microwave drying. The contents of geniposide and croein 1 were determined by RP - HPLC. RESULTS The content of two components in Fructus C, ardeniae processed by six drying methods was determined. CONCLUSION There is certain effect on geniposide and erocin 1 using different drying methods, it has better effects by oven drying under 50℃ , while the freeze - drying, vaccum drying, oven drying under 100℃ methods showed a common result. It is good for the conservation of geniposide by oven drying after steaming microwave drying.
