  Steroidal saponins from Fritillaria pallidiflora Schrenk

  摘要：

  Five new steroidal saponins, Pallidifloside D (1), Pallidifloside E (2), Pallidifloside G (5), Pallidifloside H (6) and Pallidifloside I (7), together with seven other steroidal saponins (3,4,8-12) were isolated from the dry bulbs of Fritillaria pallidiflora Schrenk. Their structures were established by spectroscopic techniques (IR, MS, 1D and 2D NMR) and chemical means. The isolated steroidal saponins were evaluated for cyotoxic activity against human C6 brain gliomas and Hela cervix cancer cell lines using MTT assays. Compounds 1, 10, 11, 12 showed cytotoxicity against C6 and Bela cell lines with IC50 values in the range of 5.1-75.8 mu M. (C) 2012 Elsevier B.V. All rights reserved.
