摘　　要：目的:研究豆科决明属植物短叶决明子的化学成分。方法:采用柱色谱、薄层色谱以及重结晶分离纯化短叶决明子的醇提物,并通过理化鉴别与波谱解析进行结构鉴定。结果:从短叶决明子分离得到7个化合物,经鉴定为1-去甲甲基钝叶决明素(Ⅰ)、橙钝叶决明素(Ⅱ)、芦荟大黄素(Ⅲ)、钝叶决明素(Ⅳ)、甲基钝叶决明素(Ⅴ)、美决明子素(Ⅵ)、橙黄决明素(Ⅶ)。结论:所有化合物均为首次从短叶决明子中分离得到。Objective： To study the chemical constituents in the seed of Cassia leschenaultiana. Methods： The compounds were separated and purified by column chromatography, thin-layer chromatography and recrystallization. The structures were identified by the physicoche mical identification and spectral analysis. Results： Seven compounds were isolated from the seeds of Cassia leschenaultiana and identified as 1-desmethylehryso-obtusin（ I ）, aurantio-obtusin（ II ）, ale-emodin（ Ⅲ ）, obtusin（ IV ）, chryso-obtusin（ V ）, ob- tusifoline（VI） and aurantio-obtusin（ Ⅶ ）. Conclusion： All of the compounds are isolated from the seeds of Cassia leschenaultiana for the first time.
