  摘要：

  Four flavonoid ketohexosefuranosides, pinnatifinoside A, pinnatifinoside B, pinnatifinoside C, and pinnatifinoside D were isolated from the leaves of Crataegus pinnatifida Bge. var. major N.E.Br. Their structures were elucidated by spectroscopic analysis (UV, IR, MS and 1D, 2D NMR) and chemical evidence. (C) 2001 Elsevier Science Ltd. All rights reserved.
