Flavonoid ketohexosefuranosides from the leaves of Crataegus pinnatifida Bge. var. major N.E.Br.
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.
