Abstract

A new strategy was developed for producing bioethanol from the residue of Chamaecyparis obtusa with simultaneously extraction of flavonoids from Chamaecyparis obtusa. By optimizing the extraction conditions, it is concluded that the highest amount of flavonoids in the extract was obtained through using methanol with heating method (60 ºC) at a solid/solvent ratio of 1:10 (g/mL) for 90 min. The total extracted amount of quercetin, myricetin and amentoflavone were 3.57, 0.05 and 0.9806 mg/g, respectively. The maximum ethanol obtained from the Chamaecyparis obtusa waste (1 g) was 0.14 g/g after 24 h of fermentation. This study exhibits an approach to make full use of plants.
