  Tetraflavonoid and biflavonoids from Aristolochia ridicula

  摘要：

  Biflavones, a chalcone-flavone, and a tetraflavonoid with a new carbon skeleton were isolated from the leaves of Aristolochia ridicula. Their structures were determined by chemical derivatizations and spectrometric analyses. (c) 2008 Elsevier Ltd. All rights reserved.
