Abstract
Polyphenolic constituents of eighteen Ficus species were studied as separated by paper chromatography. Their inter-relationship was examined on the basis of their paired affinity (PA) indices. A comparative relationship of each Species in respect of PA values with others, are shown in polygonal graphs. Each species posses a distinct shape and area of these polygons. F. eriobotryoides , the only species native of Tropical Africa included, has distinctly smaller PA values thereby indicating its remote relationship with others. About 25-30% of the polyphenolic constituents are common in all the species, probably an indication of common heritage. At least two phenolics are found to be common to all the species studied. PA indices between 30 and 60% are shown by a fairly large group of species in each case. Considering PA values above 60% or less than 30% as indicating more nearness or remoteness respectively, it is possible to show inter-relationship among them. The various species of the subgenus Urostigma clearly isolate themselves into one group. F. virens, F. elastica and F. drupaceae var. pubescens appear to be the connecting links between the species of the subgenus Urostigma and Ficus. Details of the relationship are discussed.
