1H-NMR、13C-NMR等波譜技術(shù)確定化合物的結(jié)構(gòu)。結(jié)果:分離并鑒定了5個(gè)倍半萜類化合物,分別為特勒內(nèi)酯(1)、3-epiisotelekin(2)、11β,13-dihydro-1-epi-inuviscolide(3)、天名精內(nèi)酯酮(4)、天名精內(nèi)酯醇(5)。結(jié)論:化合物2、3為首次從天名精屬植物分離得到。;Objective: To investigate the chemical constituents from Carpesii Fructus (the dry fruits of Carpesium abrotanoides). Methods: The compounds were isolated by chromatography (silica gel, ODS, and HPLC)and identified on the basis of physico-chemical constants and spectral analysis (1H-NMR and 13C-NMR). Results: Five sesquiterpenoids were isolated and their structures were identified as telekin (1), 3-epi-isotelekin (2), 11β, 13-dihydro-1-epi-inuviscolide (3), carabrone (4), and carabrol (5). Conclusion: Compounds 2 and 3 are isolated from the plants of Carpesium L. for the first time."/>
