射干Belamcanda chinensis L.干种子150g用二氯甲烷浸泡一个月,过滤、浓缩得13g提取物。经一系列硅胶层析分得油状物射干酚(Belamcandol)A(239mg)和B(87.3mg)经光谱数据和化学降解鉴定射干酚A为2.4-二甲氧基-6-((Z)-10′-十五烯基)酚〔2,4-Dimethoxy-6-((Z)-10′-penta-decenyl)phenol,1〕;射干酚B为1-O-甲基- The dried seeds of Belamcanda chinensis L. were soaked in 150 g of dichloromethane for one month, filtered, and concentrated to give 13 g of extract. A series of silica gel chromatographs of the oils, Belamcandol A (239 mg) and B (87.3 mg) were identified by spectroscopic data and chemical degradation. The radiospray phenol A was 2.4-dimethoxy-6-((Z)- 10’-Tetradecenyl)phenol [2,4-Dimethoxy-6-((Z)-10’-penta-decenyl) phenol, 1]; Phenolic B is 1-O-methyl-
