Pyranoflavonoids are mainly distributed in Leguminosae,
Moraceae. As a potent drug candidate, pyranoflavonoids have attracted
much attention in late years due to their impressive pharmaceutical activities.
The structure characteristics, plant resources and pharmaceutical activities
of pyranoflavonoids are reviewed in this paper. The fragmentation
in mass spectrometry is also discussed for quick identification of these
chemicals. Due to the low abundance of this flavonoid sub-class in plants,
it is required to find an efficient way to synthesize them. Therefore, an
overview of chemical synthesis and biological synthesis is presented in
this paper. The information given in this paper will be helpful to know
pyranoflavonoids and to be utilized in medicines and nutraceuticals.
Keywords: Pyranoflavonoid, Synthesis, Pharmaceutical activity, Structure, Plant resource, Mass spectrometry.
