通过硅胶和MCI柱色谱以及制备液相色谱等分离方法从白苞裸蒴中分离纯化得到6个含氮类化合物,经质谱和核磁共振等波谱技术将其结构分别鉴定为2-(1-羟基-6-甲氧基-4-氧亚基环己-2-烯-1-基)乙腈(1)、10-甲氧基-1-氧杂-3-氮杂螺[4.5]癸-2,6-二烯-8-酮(2)、2-(1-羟基-4-氧亚基环己-2,5-二烯-1-基)乙腈(3)、1-氧杂-3-氮杂螺[4.5]癸-2-烯-8-酮(4)、1-氧杂-3-氮杂螺[4.5]癸-2,6-二烯-8-酮(5)、对羟基苯乙腈(6).化合物1和2为新的含氮类化合物,化合物3为新的天然产物,其余化合物均为首次从该植物中分离得到.
Six nitrogen-containing compounds were isolated and purified from the naked capsule of capsule by silica gel, MCI column chromatography and preparative liquid chromatography. Their structures were identified as 2- (1-hydroxy Methoxy-4-oxo-cyclohex-2-en-1-yl) acetonitrile (1), 10-methoxy-1-oxa-3-azaspiro [4.5] (2), 2- (1-hydroxy-4-oxycyclohexa-2,5-dien-1-yl) acetonitrile (3), 1- Diazaspiro [4.5] deca-2-en-8-one (4) Hydroxyphenylacetonitrile (6) .Compounds 1 and 2 were new nitrogen-containing compounds. Compound 3 was a new natural product. The remaining compounds were isolated from this plant for the first time.
