Summary:This study was conducted to evaluate the effects of heat treatment and germination on tricin and tricin 4'-O-(threo-${\beta}$-guaiacylglyceryl) ether (TTGE) formation from rice hull (Oryza sativa L.). Heat treatments were conducted at $80{\sim}140^{\circ}C$ for 1~5 h. Germination periods were 1~6 days at $37^{\circ}C$. Germinated rough rice extracts were classified as non-filtrated, filtrated, and residue after filtration. For heat treatment, the highest contents of tricin and TTGE were 253.12 and $208.39{\mu}g/g$ at $130^{\circ}C$ after 1 h, respectively. For germination, the highest contents of tricin and TTGE in rice hull were 118.20 and $95.37{\mu}g/g$ after 2 days, respectively. In the germinated rough rice extract treatment, the highest contents of tricin and TTGE were 361.76 and $308.08{\mu}g/g$, respectively, in residue after filtration of germinated rice extract for 6 days. Therefore, the optimum conditions for tricin and TTGE formation were heat treatment at $130^{\circ}C$ for 1 h, germination for 2 days, and addition of residue after filtration of germinated rough rice extract for 6 days. 본 연구에서는 열처리 및 발아와 발아 벼로부터 추출한 조효소액에 의한 왕겨의 tricin과 4'-O-(threo-${\beta}$-guaiacylglyceryl) ether(TTGE)의 함량 변화에 대해 살펴보았다. 열처리에 의한 왕겨의 tricin과 TTGE의 함량은 온도 및 시간이 증가함에 따라 증가하였고 $130^{\circ}C$에서 1시간 처리하였을 때 각각 253.12 및 $208.39{\mu}g/g$으로 가장 높게 나타났으며, 발아 2일차에서 각각 118.20 및 $95.37{\mu}g/g$으로 가장 높게 나타났다. 발아일수별 벼의 조효소액을 여과한 조효소액 및 여과 후 남은 잔여물을 접종한 결과 여과한 조효소액의 처리구에서는 뚜렷한 함량 차이가 없었으나 잔여물을 처리하였을 때 tricin 및 TTGE의 함량이 유의적으로 증가하였다. 특히 발아 벼 6일 차에서 각각 361.76 및 $308.08{\mu}g/g$으로 가장 많은 함량을 나타내었다. 이상의 결과로부터 tricin과 TTGE의 함량을 가장 많이 증대시킬 수 있는 조건은 발아 6일차 벼로부터 추출한 조효소액 여과 잔여물을 처리한 경우로 나타났다.
