Buck wheat is known to include valuable flavonoids, such as rutin, however, the husk have been discarded so far. The object of this study is to estimate the possibility of buck wheat as a new resource for production of valuable chemicals by extraction and fast pyrolysis. In this study, Influence of extraction of buckwheat husk on distribution of pyrolysis products was evaluated. Extraction with water and 70% methanol was significantly increased the yield of levoglucosan in the pyrolysate from extracted husk residue. Furthermore the levoglucosan yield was increased by the washing with 1% hydrochloric acid. It is thought to be because the alkali metal for promoting the decomposition of the record book is extracted. The formation of the phenol products from the pyrolysis of the buck wheat are inhibited by extraction with methanol and water.
