摘　　要：夹竹桃科药用植物盆架树(Winchiacalophylla)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。Three new compounds, butyl winchal, butyl isowinchal and ethyl winchal along with three known compounds, butyl β-D-glucofuranoside, butyl β-D-glucopyranoside and butyl α-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.
