New Naphthoquinones from Arnebia hispidissima Roots[1]

Abstract

Besides shikonin and arnebifuranone, two new shikonin esters isolated from the roots of Arnebia hispidissima have been characterized as butylshikonin and 2′-methyl-hexa-1′,3′-dienoylshikonin by physicochemical methods. Arnebifuranone is the first report from this species.
