Abstract

A new naphthoquinone dimer, arnebiabinone (1), a new phenolic compound, ethyl 9-(2′,5′-dihydroxyphenyl) nonanoate (2), and a new natural product, octyl ferulate (3), were isolated from the EtOH extract of dried roots of Arnebia euchroma (Royle) Johnst. Their structures were elucidated on the basis of chemical reaction and spectral analysis.
