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.

最近的研究表明，在有限的被子植物物种中，血管间凹处存在乙醇溶性物质。本研究旨在揭示提取物质的性质。在所调查的11科13种植物中，3科3种中均有提取物存在，表明该物质并不罕见，而是广泛存在于各种分类类群中。同样明显的是，在家庭层面上，存在或不存在不是一个特征。组织化学检查表明，提取物不是多糖和脂质。
