ABSTRACT

Sixteen compounds were isolated from Conioselinum vaginatum by silica column chromatography over silica gel and Sephadex LH-20, as well as recrystallization. On the basis of their physical and chemical properties and spectral data, their structures were identified as ligustilide (1), 1,3-dilinolein (2), coniferaldehyde (3), myristicin (4), stigmasterol (5), beta-sitosterol (6), vanillin (7), pregnenolone (8), bergapten (9), xanthotoxin (10), methyl indole-3-carboxylate (11), ferulic acid (12), (E)-3-methoxy-4,5-methylenedioxy-cinnamic alcohol (13), p-hydroxybenzaldehyde (14), 3-methoxy-4,5-methylenedioxy-acetophenone (15), and alpha-(ethoxymethyl)-4-hydroxy- benzenemethanol (16). Among them, compound 15 was a new natural product, and compounds 2, 3, 10, 11, 14, and 16 were obtained from this genus for the first time.
