目的：研究北鶴虱(天名精的果實(shí))的化學(xué)成分。方法：通過(guò)各種色譜手段（silica gel、ODS、HPLC）對(duì)北鶴虱甲醇提取物的二氯甲烷層進(jìn)行分離純化，通過(guò)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(lèi)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.
