Study on the Changing Rules of Chemical Composition of Fresh Phyllanthus emblica L.During Drying
OBJECTIVE In order to study the changing rules of chemical composition of fresh Phyllanthus emblica L during drying.METHODS The contents of rutin,gallic acid,corilagin and ellagic acid of fresh Phyllanthus emblica L.during drying were determined by HPLC,and made a comparative analysis.RESULTS When the temperature was less than or equal to 70 ℃,the contents of rutin,gallic acid,corilagin and ellagic acid of fresh Phyllanthus emblica L.increased slowly with the extended drying time.When the temperature was equal to or higher than 80 ℃,the contents of rutin,gallic acid,corilagin and ellagic acid increased quickly with the extended drying time.CONCLUSION During drying,the contents of rutin,gallic acid,corilagin and ellagic acid of fresh Phyllanthus emblica L show a trend of increase with the extended drying time.The speeds of the increase and amplitude are influenced by temperature.When the temperature is extended,the speeds of increase and amplitude are also extended,which can provide a reference for the fresh Phyllanthus emblica L.drying process.
