中文摘要：

研究崖县风车子茎的化学成分。用硅胶柱层析法、制备薄层色谱法、重结晶法和高效液相色谱法进行分离,并根据理化性质和光谱数据对分离化合物进行结构鉴定。分离并鉴定了10个化合物,分别为：3,3′,4′-tri-O-methylellagic acid（1）,3,3′-di-O-methylellagic acid（2）,hederagenin（3）,白桦脂酸（4）,6R,9R-blumenol B （5）,6S,9R-blumenol B（6）,2α,3β,23-trihydroxyolean-12-en-28-oic（7）,4-hydroxycinnamic acid（8）,咖啡酸（9）, evofolin B（10）。化合物5、6、9和10为首次从该属植物中分离得到,所有化合物均为首次从该植物中分离得到。

英文摘要：

To investigate the chemical constituents from the stems of Combretum alfredii hance. The constituents were isolated and purified by the chromatography of silica gel, preparative thin-layer chromatography, recrystallization and high performance liquid chromatography. Their structures were identified on the basis of spectral data and physiochemical characteristics. Results 10 com-pounds were isolated from 85%ethanol extracts and identified as 3,3′,4′-tri-O-methylellagic acid（1）3,3′-di-O-methylellagic acid （2）,hederagenin（3）,fatty acid（4）,6R,9R-blumenol B（5）,6S,9R-blumenol B（6）,2α,3β,23-trihydroxyolean-12-en-28-oic （7）,4-hydroxycinnamic acid（8）,caffeic acid（9）,evofolin B（10）. Compounds 5,6,9,and 10 were reported from the Combretum for the first time. All compounds were isolated from this plant for the first time.
