Chemical investigation of the rhizomes of Costus speciosus led to the isolation of a new compound, 22-ketocholesteryl palmitate (1) along with four known compounds, 24-methylenecycloartanol (2), cycloartanol (3), stigmasterol (4) and linoleic acid (5). The structure of new compound was characterised by extensive 1D-, 2D-NMR and mass spectrometry (GC-MS and HR-ESI-MS) techniques.
对闭鞘姜根茎进行化学研究，从中分离出一种新化合物22-酮胆固醇棕榈酸酯（1）以及四种已知化合物，即24-亚甲基环阿尔廷醇（2）、环阿尔廷醇（3）、豆甾醇（4）和亚油酸（5）。通过广泛的一维、二维核磁共振以及质谱分析（气相色谱-质谱联用和高分辨电喷雾电离质谱）技术对新化合物的结构进行了表征。
