새로운 농가 소득 작물로서 곰취 신품종 육성을 위한 기초자료를 얻기 위하여, 두 곰취(적곰취와 달곰)와 기존 재배종 곰취에 대한 향기 성분과 총페놀함량, DPPH 활성, 비타민 C 함량을 분석하였다. 생체중 100g 당 총페놀함량은 재배종(137.29mg) 보다 적곰취(158.40mg)와 달곰(180.82mg)에서 현저히 높았다. DPPH 활성은 재배종(74.45%)과 적곰취(75.59%)보다 달곰(86.26%)에서 다소 높았다. 비타민 C 함량은 재배종과 적곰취 보다 달곰(1.81mg)에서 다소 높았다. 향기 성분인 정유 함량은 재배종에 비하여 적곰취(0.164%), 달곰(0.290%)에서 유의하게 높았다. GC/MSD 분석의 결과 주요 물질은 재배종 곰취 43종, 적곰취 44종, 달곰 31종이 동정되었으며, N 함유 화합물은 달곰에서만 검출되었다. 향취를 나타내는 주요 6종의 향기 성분 (a-pinene, ${\beta}$-pinene, ${\beta}$-phellandrene, a-phellandrene, 3-carene, limonene) 함량은 재배종에 비하여 적곰취가 높았으며, 달곰은 상대적으로 낮았다. 특히 달곰은 총페놀함량, DPPH 활성, 비타민 C 함량, 정유함량 등에서 재배종 및 적곰취보다 유의하게 높은 것으로 나타나, 우수한 특성을 기진 것으로 판단되었다.
This study was conducted to compare the aromatic compounds and the internal quality such as total phenolic contents, DPPH activity, and vitamin C contents in two new forma (red type and dalgom) and gom-chwi (Ligularia fischeri). Total phenolic contents were indicated 137.29mg/100g fresh wt. in gom-chwi, 158.40mg/100g fresh wt. in red type, and 180.82mg/100g fresh wt. in dalgom, red type and dalgom had higher contents than gom-chwi. DPPH activities were appeared similar result in gom-chwi (74.45%) and red type (75.59%), and dalgom (86.26%) had better than others. In vitamin C contents, gom-chwi and red variety had shown very closed results but dalgom had best result (1.81mg/100g fresh wt.). Essential oil contents of red type (0.164% of fresh wt.) and dalgom (0.290% of fresh wt.) had higher contents than gom-chwi (0.060%). Analysis of major components of essential oil by GC/MSD, identified 43 compounds in gom-chwi, 44 compounds in red type, and 31 compounds in dalgom. N-containing compound only detected in dalgom. Comparison of six aromatic compounds for fragrance (a-pinene, ${\beta}$-pinene, ${\beta}$-phellandrene, a-phellandrene, 3-carene, and limonene) was indicated red type had higher contents and dalgom had lower contents than gom-chwi. Dalgom had higher contents of total phenolic, DPPH activity, vitamin C, and essential oil than red type and gom-chwi. This result had shown the dalgom had better characters for new cultivar.
