[Study on Chemical Constituents from Carpesium abrotanoides].

To study the chemical constituents from Carpesium abrotanoides.Compounds were isolated and pu- rified by silica gel and Sephadex LH-20 column chromatography, their structures were determined by using spectroscopic analysis.Ten compounds were isolated and identified as Vomifoliol (I), 2-Desoxy-4-epi-pulchellin (II), 8-epi-Confertin (III), 1-epi-Inuviscolide (IV), Telekin (V), Isotelekin (VI), 4 (15)-β-Epoxyisotelekin (VII), Carabrone (VIII), Carabrol (IX), and 3- Deuteriomethyl-5-methyl-2,3-dihydrobenzofuran (X).Compounds I, III, IV,VII, VII and X are isolated from this plant for the first time.
