 Title    Facile Synthesis of the Chalcones and Dihydrochalcones from Naringin, Neohesperidin and Hesperidin  
 Abstract    The flavanone glycosides naringin, neohesperidin and hesperidin were converted chemically to the corresponding chalcones and dihydrochalcones; the one-step synthesis, performed at room temperature, required the presence of 25% K O H in the reaction mixture for the former and 10% K O H , a catalyst and molecular hydrogen at atmospheric pressure for the latter.

 Title    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 range 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 micro­ biological studies.
