Abstract

Abstract From the trunkwood of Tabebuia ochracea, β-sitosterol, cycloolivil, lapachol, and seven furanonaphthoquinones including the known 2-(1-hydroxyethyl) naphtho [2, 3-b] furan- 4, 9-quinone were isolated. The six new furanonaphthoquinones comprise three similar C 2 alcohol-ketone pairs at C-2 as proved by oxidations with pyridinium chlorochromate. 2- Acetyl-6-methoxynaphtho [2, 3-b] furan-4, 9-quinone was shown to be different from the ...
