℃减压干燥后用无水乙醇重结晶,得白色针状结晶
5mg。将此针晶与薯蓣皂苷元对照品进行TLC分
析,Rf值完全一致。将此再同做IR谱,图谱完全重
叠,证明皂苷元为薯蓣皂苷元。
将上述酸水解液用lmol/LNaOH液中和,浓
缩后进行TLC分析,用展开剂⑥展开,显色剂⑤显
色,D一葡萄糖与L一鼠李糖作对照品,从水解液中检
出葡萄糖与鼠李糖。
皂苷D的部分水解:取约150mg皂苷D于lO
mL试管中,加3mL1mol/LHCl溶液溶解。置此
试管于沸水浴中加热20min,冷却。滤出沉淀,用1
mL甲醇溶解,与皂苷A、B、C和次生苷I、Ⅱ同做
硅胶H、TLC分析,用展开剂②展开,显色剂①显
色。水解物呈现7个斑点,其中极性小的5个斑点的
Rf值均与皂苷A、B、C和次生苷I、1I完全一致,另
换两种展开剂①、③展开,作相同对照操作,仍得到
完全相同结果。取硅胶H制备色谱板(20em×10
cmx0.1cm)一块,用微量注射器吸取上述沉淀溶
解的甲醇液500弘L,成条状(2cm)点样于板底部,
挥去溶剂后于层析缸中用展开剂②展开。展开完全
后取出,挥干溶剂再展开1次,取出晾干,置碘缸中
碘蒸气显色3~5min,取出立即用铅等划出极性小
的5条色带的边界。挥去碘用刮刀刮下各色带的吸
附剂,分别置于G。玻沙漏斗中用5mL甲醇洗脱,
抽滤。滤液置10mL蒸发皿内蒸干溶剂,刮下各残
留物以KBr压片分别做IR光谱。所得的IR谱分别
与次生苷I、Ⅱ,皂苷A、B、C的IR谱完全重合。此
确定了皂苷D部分水解所得的7个次生苷中有5
个分别为次生苷I、Ⅱ,皂苷A、B、C。
致谢:13C—NMR、DEPT及FAB—MS谱由军事
医学科学院仪器中心代测,IR谱由本所仪器室代做。

摘 要:目的研究二蕊荷莲豆Drymariadiandra的化学成分。方法采用大孔树脂D一101,硅胶柱色谱和PR一18
进行反复分离纯化,通过波谱分析方法鉴定化合物结构。结果分离并鉴定了2个化合物:6一羧甲基一5,7,4-三羟
基黄酮(I)和4CE3,8EEl—N-[2’一D一羟基一十六烷酰基]一1一O—D一吡喃葡萄糖基一4,8一二烯一十八鞘氨醇(大豆脑苷I,
I)。结论化合物I为新化合物,化合物I首次从该植物中分离得到。
