本文对豆科植物十瓣花的化学成分进行了研究。采用硅胶、RP-C_（18）、Sephadex LH-20、制备型高效液相色谱等方法对其化学成分进行分离纯化，并根据波谱数据、理化性质及相关文献对其结构进行鉴定。从十瓣草70%乙醇提取物中分离得到三对新的二苯并草碱衍生物，分别鉴定为原皂苷A（1a）、异原皂苷A（1b）、原皂苷b （2a）、异原皂苷b （2b）、原皂苷C（3a）和异原皂苷C（3b）。
The present study investigated the chemical constituents of Caesalpinia decapetala in the Fabaceae family. The chemical constituents were isolated and purified by chromatographies with silica gel, RP-C_(18), Sephadex LH-20, and preparative HPLC, and their structures were determined based on the spectroscopic data and physicochemical properties, as well as relevant references. Three pairs of new dibenzoxocin derivatives were isolated from 70% ethanol extract of C. decapetala and identified as protosappanoside A(1 a), isoprotosappanoside A(1 b), protosappanoside B(2 a), isoprotosappanoside B(2 b), protosappanoside C(3 a), and isoprotosappanoside C(3 b), respectively.
