Abstract

Three new hydroquinone terpenoids with benzogeijerene skeletons, euchroquinols A–C (1–3), and a new monoterpenylbenzenoid, 9,17-epoxyarnebinol (4), along with five known compounds were isolated from the stem bark of Arnebia euchroma. Shikonin (6) exhibited potent anti-HCV activity with a selective index of 43.56, and compounds 1, 6, and des-O-methyllasiodiplodin (7) showed anti-Staphylococcus aureus activity with MICs of 0.5, 0.125, and 0.125 mg/mL, respectively.

Key words

Arnebia euchroma - Boraginaceae - hydroquinone terpenoids - monoterpenylbenzenoid - anti-HCV activity - antibacterial activity
