Determination of Indole Glucosinolate Content in Some Cruciferous Vegetables

本研究主要目的為探討十字花科蔬菜，高麗菜、花椰菜、山東白菜及青花菜之??硫糖?[indole glucosinolate （GS）]含量。四類蔬菜所含??硫糖?主要為3-indolylmethyl-GS，及1-methoxy-3-indolylmethyl-GS。高麗菜、花椰菜及青花菜都以3-indolylmethyl-GS含量較高，而山東白菜則以1-mehoxy-3-indolylmethyl-GS含量較高。分析南部、中部及梨山三個主要產區之高麗菜、花椰菜及山東白菜之??硫糖?含量顯示，於三個產區之高麗菜及花椰菜亦都以3-indolylmethyl-GS的含量較多。南部及中部所測得??硫糖?含量以高麗菜及山東白菜差異較大，而花椰菜則差異不明顯。但此二種蔬菜由梨山地區所得的含量都較中、南部的含量低。高麗菜、花椰菜及山東白菜經加熱處理後，發現3-indolylmethyl-GS的損失都較1-methoxy-3-in“dolylmethyl-GS的損失程度低。

Content of indole glucosinolate in cabbage, Chinese cabbage, cauliflower and broccoli were determined. The results indicated that the major indole glucosinolate (GS) in these four cruciferous vegetables were 3-indol-ylmethyl-GS and 1-methoxy-3-indolylmethyl-GS. Cabbage, broccoli and cauliflower contained higher level of 3-indolylmethyl-GS, while Chinese cabbage contained a higher level of 1-methoxy-3-indolylmethyl-GS. The indole glucosinolate in cabbage, cauliflower and Chinese cabbage from different cultivation areas, including southern Taiwan, central Taiwan and Li-San area of Taiwan, were determined. The cabbage and cauliflower from these areas contained a higher amount of 3-indolyl-methyl-GS. The contents of indole glucosinolate in cabbage and Chinese cabbage had greater differences between the southern and central Taiwan, but not for cauliflower. In general, the indole glucosinolate content of cabbage and cauliflower from Li-San area was lower than those from the other two areas. The thermal degradation of 1-methoxy-3-indolylmethyl-GS in cabbage, cauliflower and Chinese cabbage was greater than that of 3-indolylmethyl-GS.
