摘要
从短茎古当归〔Ａｒｃｈａｎｇｅｌｉｃａｂｒｅｖｉｃａｕｌｉｓ（Ｒｕｐｒ．）Ｒｃｈｂ．〕根中分得６个结晶，采用ＩＲ、ＭＳ、ＮＭＲ等方法，鉴定了４个化合物，即甲氧基欧芹素（蛇床子内酯，ｏｓｔｈｏｌ，Ⅰ）、欧前胡素（ｉｍｐｅｒａｔｏｒｉｎ，Ⅱ）、古当归素（ａｒｃｈａｎｇｅｌｉｃｉｎ，Ⅳ）、二十八烷酸（ｏｃｔａｃｏｓａｎｉｃａｃｉｄ，Ⅴ）。结晶Ⅳ和Ⅴ为首次从该植物中分出。古当归素为生物合成中最高阶段产物。
Four coumarins, one fatty acid and triterpenoid
were isolated from the root of Archangelica brevicaulis (Rupr.) Rchb. The four compounds were
identified as osthol (Ⅰ), imperatorin (Ⅱ), archangelicin (Ⅳ), octacosanoic acid (Ⅴ) by means of
IR, MS, NMR, spectral evidences. The chemical data procured would afford basis information and
use for the study of A. brevicaulis (Rupr.) Rchb.
