摘　　要：魔芋飞粉通过 95 %工业酒精提取 ,三氯甲烷和正丁醇分别萃取后 ,进行氧化铝干柱层析和高效液相色谱层析纯化获得了纯样品Ⅰ ,Ⅱ .对纯样品Ⅰ进行了傅里叶红外 (IR)、氢核磁共振 (1HNMR)、质谱 (MS)分析 ,并对其图谱进行解析 ,推断样品Ⅰ是一种 5—甲基咪唑的衍生物 .The alkaloids were extracted from konjac light-flour with 95% ethanol, then extracted with chloroform and butanol individually before purifying with dry alumina column chromatography(DACH) and high performance liquid chromatography(HPLC) to get pure samples. Sample I was studied with infrared spectroscopy (IR), 1H nuclear magnetic resonance spectroscopy(1H NMR) and mass spectroscopy (MS), then was identified to be a derivative 4-Methyl-1H-Imidazole
