Abstract

The volatile and semi-volatile compounds of 5 accessions of domestic scented and 25 accessions of introduced scented were extracted by solid phase microextraction (SPME) and analyzed by gas chromatographymass spectrum (GC-MS). A total of 156 volatile and semivolatile compounds were identified from 30 accessions of aromatic rice, including 32 alcohols, 25 acids, 25 ketones, 21 hydrocarbon, 18 esters, 16 aldehydes, 4 ethers, 5 amines, 2 phenols, 2 bases, and 8 miscellaneous compounds. By UPGMA/Neighbor-join tree analysis, the thirty accessions of aromatic rice could be classified into seven groups according to the major odor or aroma compounds. Group I included indica type of Basmati varieties. Group II and Group IV included japonica type introduced scented. Group III consisted only Hyangmibyeo1ho in domestic scented. Group V and Group VII included indica type of Basmati and non-Basmati varities. Group VI included four of domestic scented of seven accessions excepted Basmati6129, Basmati 6311, and Seratus Malam.

국내 육성향미자원과 도입 향미 유전자원의 2AP 함량을 비교분석하여, 2AP 함량이 높고 농업적 형질이 우수한 자원을 30품종의 향미 유전자원에서 방향성 화합물을 SPME 추출법으로 추출하고 GC-MS로 각 자원이 가지는 방향성 화합물을 비교분석 및 동정하였다. 1. 3종류의 유기용매의 2AP 추출효율은 ethanol > acetonitl > methanol 순으로 확인되었으며, ethnaol의 경우 $30{\sim}90^{\circ}C$의 온도범위에서 3가지 유기용매 중 ethanol이 2AP 추출효과가 가장 뛰어났고, 특히 $90^{\circ}C$에서 30분간 추출하였을 때 2AP 추출함량이 가장 높았고 추출 시간이 경과할수록 2AP의 함량이 감소하였다. 현미의 분쇄정도에 따른 2AP 추출함량은 5초간 분쇄하였을 경우 가장 높았으며 분쇄 시간이 길어질수록 낮아지는 경향이었다. 2. 선발자원의 향에 대한 관능검사는 국내 향미자원 5품종 중 Hyangmibyeo1ho, Arnaghyangchalbyeo가 중간 정도의 향을 띄었고 인디카형 도입자원 19품종 중에서 11품종과 자포니카형 도입자원 6품종 중 2품종이 중간 이상의 향을 나타났다. 3. 30품종의 평균 2AP함량은 국내 육성 향미자원이 도입 향미자원에 비해 낮았으며 도입자원에서는 인디카형이 자포니카형 보다 높은 2AP 함량을 나타내었다. 4. 156종의 방향성 화합물 기능기별로 분류하면 alcohol류 33종, acid류 23종, ketone류 24종, hydrocarbon류 20종, ester류 16종, aldehyde류 16종, ether류 4종, amine류 5종 phenol류 3종, base류 2종, 및 기타 10종으로 분류되었다. 5. 156종의 방향성 화합물 중 생태형별 출현빈도가 50% 이상인 방향성 화합물을 살펴보면, 국내육성 향미자원에서는 2-acetyl-1-pyrroline 외 28종, Japonica type 도입 향미자원에서는 9,12-octadecadienoic acid 외 31종, Indica type 도입 향미자원에서는 naphthalene 외 23종이었다. 6. GC-MS 분석결과 검출된 국내 육성 향미자원의 방향성 화합물의 수는 평균 38개($36{\sim}41$개), 평균 total peak area는 61.1%($51.6{\sim}79.3%$)이었다. 도입 자포니카형 향미자원의 방향성 화합물의 수는 평균 39개($26{\sim}45$개), 평균 total peak area는 63.2%($40.9{\sim}81.9%$)이었다. 도입 인디카형 향미자원의 방향성 화합물의 수는 평균 39.6개($26{\sim}53$개), 평균 total peak area는 72.8%($33.8{\sim}98.8%$)이었다. 7. 30 품종으로부터 검출된 156종의 방향성 화합물의 출현 유무(0/1)를 기본 matrix로 하여, UPGMA/Neighbor-join tree 분석을 통해 분류한 결과, 7개의 그룹(Group $I{\sim}VII$)으로 나눠어졌다. 각 그룹의 66% 이상의 자원에서 나타난 향(aroma/odor)성분을 살펴보면, alcohol, aldehyde, acid, ether류 등의 휘발성 성분들의 비율이 품종별로 높았다. 따라서 본 실험의 결과는 대량의 향미 유전자원의 방향성 화합물에 대한 GC/GC-MS분석결과로, 향후 우수한 향미 품종 육성에 필요한 자료로 활용될 수 있다고 사료된다.
