초록

생무우(태백무우, 알타리무우)에 존재하는 휘발성 함유황화합물을 수증기 증류 및 용매추출($CCl_4$)방법에 의해 추출하여 GC/MS 분석법에 의해 분리 확인하였다. 수증기 증류로 얻은 2종 무우의 휘발성 함유황 성분들의 GC profile은 유사하였으며, 4-methyl-pentyl, 3-methylthiopropyl, 4-methylthio-3-butenyl, 4-rnethylthiobutyl, 5-methylthiopentyl isothiocyanate 와 5-methylthio-4-pentenenitrile, 1-methylthio-3-pentanone, dimethyl sulfides 등이 분리 확인되었다. 한편 $CCl_4$추출물에는 4-methylsulfinyl-3-butenyl isothiocyanate도 존재하였다. 수증기 증류에서 는 4-methylthiobutyl isothiocyanate가, 그리고 $CCl_4$추출에서 는 4-methylthio-3-butenyl isothiocyanate가 각각 주된 휘발성 함유황 화합물이었다.

The volatile sulfur components from two varieties of radishes ('Taeback' and 'Altali'), obtained by steam distillation and solvent ($CCl_4$) extraction, were isolated and charac-terized by GC/MS analysis. The GC profile of the volatile sulfur com-pounds in the steam distillates from two types of radishes was quite similar. 4-Me-thylpentyl, 3-methylthiopropyl, 4-methylthio-3-butenyl, 4-methylthiobutyl and 5-methyl-thiopentyl isothiocyanates, 5-methylthio-4-pentenenitrile, 1-methylthio-3-pentanone, and dimethyl sulfides were commonly identified. In the $CCl_4$ extract, 4-methylsulfinyl-3-bu-tenyl isothiocyanate was obtained as another major constituent. Whereas 4-methylthiobutyl isothiocyanate was found to be a predominent component in the steam distillate, 4-methylthio-3-butenyl isothiocyananate was a major one in the $C1_4$ extract.
