过山蕨中1个新结构三萜皂苷的结构鉴定

A new 9,19-cycloartane glycoside from Asplenium ruprechtii

对过山蕨水提物化学成分进行了研究。采用硅胶柱色谱、凝胶(Sephadex LH-20)柱色谱、制备高效液相色谱等方法分离纯化过山蕨水提物中的化学成分,并根据波谱数据进行结构鉴定。从中分离鉴定了5个化合物,分别为aspleniumside G(1),trans-p-coumaric acid(2),trans-p-coumaric acid 4-O-β-D-glucoside(3),cis-p-coumaric acid 4-O-β-D-glucoside(4)和(E)-ferulic acid-4-O-β-D-glucoside(5)。其中化合物1为新结构三萜皂苷类化合物。

Chemical constituents of water extracts of Asplenium ruprechtii were investigated.Five compounds were isolated by silica gel,Sephadex LH-20 gel column chromatographies and preparative HPLC,and their structures were identified by various spectral analyses as aspleniumside G(1),trans-p-coumaric acid(2),trans-p-coumaric acid 4-O-β-D-glucoside(3),cis-p-coumaric acid 4-O-β-D-glucoside(4),and(E)-ferulic acid-4-O-β-D-glucoside(5).Among them,compound 1 is a new 9,19-cycloartane glycoside.
