Abstract

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.

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.
