摘要
研究豆科云实属植物云实Caesalpinia decapetala的化学成分。采用硅胶、反相C18、Sephadex LH-20凝胶柱色谱、制备型HPLC等方法进行分离纯化,根据理化性质、波谱数据结合参考文献鉴定化合物结构。从云实皮70%乙醇提取物中分离得到3对二苯并氧辛类新化合物,分别鉴定为protosappanoside A(1a)和isoprotosappanoside A(1b)、protosappanoside B(2a)和isoprotosappanoside B(2b)、protosappanoside C(3a)和isoprotosappanoside C(3b)。以上化合物均为二苯并氧辛类新化合物。
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-C18,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(1a),isoprotosappanoside A(1b),protosappanoside B(2a),isoprotosappanoside B(2b),protosappanoside C(3a),and isoprotosappanoside C(3b),respectively.
