  A flavone dimer from Ouratea hexasperma

  摘要：

  From the leaves of Ouratea hexasperma, the flavone dimer 4',5,7-trihydroxyflavone-(6 --> 8 ")-4''', 5 "-dihydroxy-7 "-methoxyflavone was isolated in addition to methyl myoinositol. The structures were established by various analyses including 2D-NMR spectroscopy. (C) 1999 Elsevier Science Ltd. All rights reserved.
