Flavonoids on Citrus and Related Genera

Part III. Falvonoid Pattern and Citurs Taxonomy

抄録

The occurrence and distribution of flavanone glycosides in flowers, young and mature leaves, young and ripe fruits, dividing them into peels, segment membranes and juices, of many kinds of citrus were investigated. The occurrence of narirutin, eriocitrin and neoeriocitrin is fairly common to a number of species in genus citrus. Results also indicate that flavonoid patterns in citrus can be classified into eleven groups or more and further they can be summarized in two large groups: (a) those composed of flavanone rutinosides and (b) those composed of flavanone neohesperidosides. Thus the chemotaxonomic table of citrus was given as the results of our study in connection with the Tanaka's classification.
Flavonoids in some artificial citrus hydrids were also studied.
