Abstract
브로콜리 중의 bioactive organosulfur phytochemicals를 분석하기 위해 브로콜리를 용매추출하여 GC/MSD에 의해 분리동정하였다. 브로콜리에 함유된 phytochemicals 중에서 isothiocyanate류가 40.42%로 대부분을 차지하였으며, glucosinolate 분해산물인 nitrile류는 5.12%로 isothiocyanate류에 비해 적었고, sulfide류는 0.84%로 매우 적었다. 분리 동정된 isothiocyanate류의 종류로는 3-butenyl, 4-methylthiobutyl, 4-methylthio-3-butenyl, 5-methylthiopentyl, 2-phenylethyl, 3-methylsulfinyl propyl 및 4-methylsulfinylbutyl isothiocyanate의 7종이었다. Isothiocyanate류 중에서 3-butenyl isothiocynate는 22.05%로 가장 많았으며, 그 다음으로 sulforaphane 16.50%로 2종의 isothiocyanate가 대부분을 차지하였다. Nitrile의 종류는 4-methylthiobutyl, 5-methylthiopentyl, 2-phenylethyl 및 4-methylsulfinylbutyl nitrile의 6종류가 확인되었다. 한편, 동정된 sulfide 종류로는 dimethyl disulfide, dimethyl trisulfide 및 dimethyl tetrasulfide이었다.
