Three new triterpenoid saponins, impatiprins A-C (1-3), together with a known triterpenoid (4) and two known triterpenoid saponins (5, 6), were isolated from the rhizomes of Impatiens pritzellii Hook. f. var. hupehensis Hook. f. The structures of 1-3 were determined by 1D and 2D NMR, FAB-MS techniques and chemical methods. Compounds 1 and 2 showed weak cytotoxicities against S-180, HeLa and HepG2 cell lines.
从湖北凤仙花（Impatiens pritzellii Hook. f. var. hupehensis Hook. f.）的根茎中分离得到了3个新的三萜皂苷，凤仙皂苷A-C（1-3），以及1个已知的三萜（4）和2个已知的三萜皂苷（5, 6）。通过一维和二维核磁共振、快原子轰击质谱技术及化学方法确定了1-3的结构。化合物1和2对S-180、HeLa和HepG2细胞系显示出较弱的细胞毒性。
