삼채의 잎과 뿌리로부터 휘발성 화합물과 아미노산을 분석하였다. 휘발성 향기성분은 Headspace GC-MS방법으로 분석하였다. 잎 조직으로부터 18종의 휘발성화합물이 검출되었고, 21종의 화합물은 뿌리조직으로부터 분석되었다. 주요 향기성분은 diallyl disulphide였고, 잎(27.9%)과 뿌리(17.41)에서 가장 많이 함유하고 있었다. 또 다른 주요 황화합물은 methyl 2-propenyl disulfide, dimethyl disulfide, methyl 1-propenyl disulfide과 methyl 2-propenyl trisulfide이 잎과 뿌리에 모두 함유하고 있었다. 전체 46종 화합물 중 가장 많이 함유하고 있는 물질군은 황화합물이었다. 황화합물은 엽조직에 6종, 뿌리조직에는 5종이 함유되어 있었다. 또한 유리아미노산과 polyphenol성 화합물은 잎과 뿌리 조직에서 분석하였다. 잎과 뿌리 조직에서 아미노산은 20종과 19종이 각각 검출되었다. 총아미노산의 함량은 잎에서 0.134 mg/g, 뿌리조직에서 0.105 mg/g 함유하고 있었다. 총 polyphenol성 화합물 함량은 잎에서 0.28 mg/g, 뿌리에서 1.08 mg/g 함유하고 있었다. 이 결과는 삼채의 이용과 효율적인 재배에 기초자료를 제공할 수 있다.
The volatile aroma components and amino acids were analyzed from leaf and root tissues of Allium hookeri Thwaites. The volatile aroma components were collected by Headspace apparatus and identified by gas chromatography-mass spectrometry (Headspace GC-MS). The 18 volatile compounds were identified in the leaf tissue, on the other hand, the 21 compounds were identified in the root tissue in this experiments. The most abundant aroma compound was diallyl disulphide, which composed mainly on leaf and root tissues, 27.9% and 17.41%, respectively. Also other sulfur-containing compounds such as methyl 2-propenyl disulfide, dimethyl disulfide, methyl 1-propenyl disulfide and methyl 2-propenyl trisulfide were contained in both tissues. Among total of 46 components, the most abundant compound group was sulfur-containing compounds. Sulfur-containing compounds were identified 6 kinds in leaf tissue and 5 kinds in root tissue. In addition, free amino acid and total polyphenolic compounds were analyzed in the leaf and root tissues. Amino acids in leaf and root tissues were identified 20 and 19 kinds, respectively. Content of amino acid contained 0.134 mg/g in leaf and 0.105 mg/g root tissue. Content of total polyphenolic compounds were highest in leaf (0.28 mg/g) compared to root tissue (1.08 mg/g). These results can be served as basic data for efficient cultivation and utilization of A. hookeri Thwaties.
