  Steroidal glycosides from the underground parts of Trillium erectum and their cytotoxic activity

  摘要：

  Six steroidal glycosides, along with 14 known compounds, were isolated from the underground parts of Trillium erectum L. (Liliaceae). The structures of 1-6 were determined on the basis of extensive spectroscopic analysis, including two-dimensional (2D) NMR data, and a few chemical transformations. The isolated compounds were evaluated for their cytotoxic activity against HL-60 human promyelocytic leukemia cells. (C) 2008 Elsevier Ltd. All rights reserved.
