Research Abstract

Recent studies have revealed that ethanol-soluble materials are present in intervessel pits in a limited angiospermous species. This study was aimed to reveal the nature of the extractive materials. The extractives were present in 3 species representing 3 families of a total of 13 species representing 11 families examined, an indication that the materials are not rare but widely appear in a variety of taxonomic groups. It was also apparent that the presence or absence is not a feature at the level of family. Histochemical examinations have revealed that the extractive materials are not polysaccharides and lipids.
