运用硅胶、Sephadex LH20、ODS以及高效液相色谱法,从九子参的根中分离得到一个新三萜皂苷和一个已知三萜皂苷。通过质谱以及一维二维核磁确定了化合物的结构。化合物1和2均为首次从该属植物中分离得到。
A new triterpene saponin and a known triterpene saponin were isolated from the roots of P. trifoliate with silica gel, Sephadex LH20, ODS and HPLC. The structure of the compound was confirmed by mass spectrometry and one-dimensional two-dimensional NMR. Compounds 1 and 2 were isolated from this genus for the first time.
