Dihydrochalcones and Chalcones of Some Flavanone Glycosides: Qualitative and Quantitative Determinations

Abstract

The chalcones and dihydrochalcones of the flavanone glycosides naringin, neohesperidin and hesperidin were separated and identified by thin-layer chromatography; a similar procedure was utilized to perform preparative TLC for purification of these Compounds. A new spectrophotometric method for the quantitative determination of dihydrochalcones in the concentration ränge from 0.005 to 0.100% in aqueous or alcoholic Solution is described as well as a detection method of these Compounds in agar media for microbiological studies. © 1975, Walter de Gruyter.
