目的 研究云实Caesalpinia decapetala种子的化学成分。方法 采用硅胶、Sephadex LH-20、ODS等柱色谱技术进行分离纯化,采用各种波谱技术进行结构鉴定。结果 从云实种子95%甲醇提取物中分离得到了1个新卡山烷二萜类化合物,鉴定为1α,2α-diacetoxy-14β-carboxymethyl-7β-hydro xyl-vouacapen-5α-ol (1)。结论 化合物1为新的卡山烷二萜类化合物,命名为云实子C。

Objective To study the chemical constituents from the seeds of Caesalpinia decapetala. Methods The constituents were isolated and purified by silica gel chromatography repeatedly, and the structures were identified by spectral analyses. Results One new cassane diterpene was isolated from the seeds of C. decapetala and its structure was identified as 1α,2α-diacetoxy-14β-carboxymethyl-7β-hydroxyl-vouacapen-5α-ol (1). Conclusion Compound 1 is a new cassane diterpene named as caesaldecape C.
