Abstract: Three new compounds, butyl winchal , butyl isowinchal and ethyl winchal along with three known compounds, butyl β-D-glucofuranoside , butylβ-D-glucopyranoside and butylα-D-glucopyranoside , were isolated from the stem barks of Winchia calophylla dealt with hydrochloric acid and aqueous ammonia. Their structures were established by spectroscopic methods, especially 2D NMR data . They are probably artificial products .

Key words: Winchia calophylla

摘要： 夹竹桃科药用植物盆架树( Winchia calophylla) 茎皮的乙醇提取物, 经石油醚脱脂后用盐酸和氨水处理, 再用石油醚、氯仿和正丁醇萃取。从正丁醇部分分离出6 个化合物, 其中3 个为新成分, 分别命名为盆架丁基缩醛、异盆架丁基缩醛和盆架乙基缩醛; 另3 个已知化合物依次为丁基-β-D-呋喃葡萄糖甙、丁基-β-D-吡喃葡萄糖甙和丁基-α-D-吡喃葡萄糖甙。他们可能是人工产物。
