무(5종) 및 무씨(왕관)에 존재하는 glucosinolate를 동정 및 정량하고 열처리에 따른 그 분해산물의 함량을 분석하였다. 왕관, 태백, 대장군, 대부령, 364호 무 및 왕관 무씨의 glucosinolate 분석결과 왕관이 다른 품종보다 많은 종류의 glucosinolate가 동정되었으며 GC법에 의한 총 glucosinolate 함량은 1.25, 1.10, 0.97, 0.96, 0.90 및 2.14 ${\mu}mole/g$이었다. $100^{\circ}C$에서 20분 열처리시 무의 indoleacetonitrile의 생성량은 왕관, 대장군, 태백, 대부령, 364호 무 및 왕관 무씨에서 0.28, 0.20, 0.23, 0.21, 0.24 및 0.58 ${\mu}mole/g$으로 왕관 무씨가 무보다 높게 나타났으며 무 품종간의 차이는 거의 없었다. Thiocyanate 이온의 함량은 열처리 시간이 경과함에 따라 점차 증가하다가 30분 경과시에 최대치를 보였다.

Glucosinolates from radish (Wangkwan, Daejangkun, Taebaek, Daebooryeung and No. 364) and its seed (Wangkwan) were identified, and their degradation product by heat treatment was analyzed. The Wangkwan variety contained much more types of glucosinolates than other radish varieties. Total glucosinolate contents of Wangkwan, Daejangkun, Taebaek, Daebooryeung, No. 354 and Wangkwan seed by GC method were 1.25, 1.10, 0.97, 0.96, 0.90 and 2.14 ${\mu}mole/g$, respectively. The indoleacetonitrile contents after 20 minutes' heat treatment at $100^{\circ}C$ from Wangkwan, Daejangkun, Taebaek, Daebooryeung, No. 364 and Wangkwan seed were 0.28, 0.20, 0.23, 0.21, 0.24 and 0.58 ${\mu}mole/g$, respectively. The heat treatment increased the thiocyanate ion contents in radish and its seed, and the contents were maximum at 30 min.
