目的对苦石莲中的化学成分做进一步研究。方法采用硅胶柱色谱、凝胶柱色谱和重结晶等多种方法分离纯化,根据理化性质及波谱学数据进行结构鉴定。结果分离得到9个化合物,分别鉴定为全反式-5-脱氧戊糖酸-γ-内酯(all-trans-5-deoxy-pentonic acid-γ-lactone,1)、腺苷(adeno-sine,2)、胡萝卜苷-6’-O-硬脂酸酯(daucosterol-6’-O-stearate,3)、7-acetoxybonducellpin C(4)、caesal-pinin K(5)、norcaesalpinin E(6)、neocaesalpin A(7)、neocaesalpin L(8)、neocaesalpin M(9)。结论化合物1、2为首次从云实属植物中分离得到,化合物3～5、7为首次从喙荚云实植物中分离得到。
Objective To further study the chemical constituents of Kadsura. Methods The compounds were separated and purified by silica gel column chromatography, gel column chromatography and recrystallization. The structures were elucidated on the basis of physico-chemical properties and spectroscopic data. Results Nine compounds were isolated and identified as all-trans-5-deoxy-pentonic acid-γ-lactone (1), adeno-sine 2), daucosterol-6’-O-stearate (3), 7-acetoxybonducellpin C (4), caesal- pinin K (5), norcaesalpinin E , Neocaesalpin A (7), neocaesalpin L (8), neocaesalpin M (9). Conclusion Compounds 1 and 2 were isolated from the genus Caesalpinia for the first time. Compounds 3 to 5 and 7 were isolated from the genus Curvularia for the first time.
