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.
报春花科琉璃草属植物琉璃草根皮富含萘醌类化合物,如alkanins 和 shikonins。本研究从树皮的石油醚(60-80°C)提取物中分离出 alkanin/shikonin 的二聚体,并通过光谱研究(UV、IR、NMR、MS 和 DEPT)阐明了其结构。石油醚提取物中含有 62.4%(w/w)的 alkanin/shikonin 二聚体,在白化大鼠的切除和切口伤口模型中研究发现,该化合物可促进伤口愈合过程。
