摘要
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 (60-80C) 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.
