Root bark of Onosma echioides belonging to the family Boraginaceae is reported to be rich in naphthaquinones such as alkannins and shikonins. In this study, a dimer of alkannin/shikonin was isolated from the petroleum ether (60–80 C) extract of the bark, and the structure of the same was elucidated through spectral studies (UV, IR, NMR, MS and DEPT). The petroleum ether extract was found to contain 62.4% (w/w) of the dimer of alkannin/shikonin, and the compound is found to promote wound-healing process, when studied in the excision and incision wound models in albino rats.
