Abstract:
OBJECTIVE:To further exploit the active components from Loquat leaf and its gruffs.METHODS:The chief components in loquat leaf and its gruffs were extracted by ultrasound extraction and Soxhlet extraction,respectively,the sepa?ration of ursolic acid and other constituents was performed by HPLC,and the relative amounts of which were determined and compared.RESULTS:Soxhlet extraction is superior to ultrasound extraction in the extraction of loquat leaf and8components in gruffs.Under the same extraction method,the content of ursolic acid in loquat leaves is equivalent to that of gruffs.Besides,the contents of6components in gruffs were above those in loquat leaves.CONCLUSION:The essential component-triterpenic acid in loquat leaves suffered no loss after extraction with water,the active components in gruffs can be further exploited.
