Abstract
台灣澤蘭地上部之丙酮/甲醇 (1:1) 萃取物,經由各種層析管柱及不同溶媒系統層析後,共分離出十八個化合物,其結構根據物理數據、核磁共振光譜分析後,共分為七大類:三個黃酮類化合物1 (Eupafolin)、2 (Hispidulin)、3 (Quercetin);二個酚類化合物4 (Caffeic acid)、5 (Ethyl caffeoate);一個三?類化合物6 (3?-Friedelinol);一個二?類化合物7 (trans-Phytol);二個固醇類化合物8 and 9 (?-sitosterol and? ?-stigmasterol);一個??-內酯化合物10(3-ethoxymethyl -5H-furan-2-one);八個倍半?類化合物11 (Eupatocannabin A), 12 (Eupatocannabin B), 13 (Eupatocannabin C), 14 (Eupatocannabin D), 15 (Eupatocannabin E), 16 (Eupatocannabin F), 17 (Eupaformolactone B), 18 (Eucannabinolide),其中化合物11-16為文獻上首次發現的新化合物。此外,生物活性檢測方面,試驗的十七個化合物對於MCF-7細胞毒性試驗,而在50 μg/ml濃度下化合物1、11、12、13、14、15、16、17和18皆有明顯抑制,進一步降低濃度10 μg/ml以化合物1之細胞毒性37.85 % 為最低,化合物11、12、13、14、15、16、17和18皆在41~54 % 不等。
