Hongconin, a new naphthalene derivative from Hong-Cong, the rhizome of Eleutherine americana Merr. et Heyne (iridaceae).

Abstract

A new naphthalene derivative, hongconin, was isolated from the rhizome of Eleutherine americana MERR. et HEYNE (Iridaceae), together with three known naphthalene derivatives (1-3). The structure of hongconin was elucidated as 4 on the basis of chemical and spectral studies, and X-ray analysis.
