The following sixteen genera viz. Catalpa, Crescentia, Heterophragma (syn : Haplophragma), Kigelia, Lundia, Mansoa, Markhamia (syn : Dolichandrone), Newbouldia, Oroxylum, Paratecoma, Phyllarthron, Radermachera, Stereospermum, Tabebuia, Tecomella (syn : Tecoma) and Zeyhera have so far chemically investigated for more than sixty quinonoid constituents. Ten plant species belonging to seven genera namely Heterophragma, Kigelia, Markhamia, Phyllarthron, Stereospermum, Tabebuia and Tecomella have chemically been examined by our group during last three decades which have resulted in the isolation of two dozen of quinonoid compounds including some new naphthoquinones and their dimers. The structures of these compounds were unambiguously established from chemical and spectral evidences. Their taxonomic and biogenetic significance were discussed.
