Comparative studies on the isothiocyanate content of rape-seeds and rape-seed oil show that, apart from nearly 300 mg/100 g of vinyl thio-oxazolidone, rape-seeds contain almost 200--300 mg/100 g of isothiocyanates of which 3-butenyl isothiocyanate and 4-pentenyl isothiocyanate (ratio of 4:1) are the main components as evidenced thin-layer and gaschromatographically. Only about 1 mg/100 g of isothiocyanates are found in pressed rape-seed oil; and but circa 10 mg/100 g, in extracted rape-seed oil. 3-Butenyl isothiocyanate and 4-pentenyl isothiocyanate (ratio of 4:1) are once more the main components. Thioglycerides are not detected in the oil. Vinyl thio-oxazolidone is found only in extracted rape-seed oil (about 2 mg/100 g).
对油菜籽和菜籽油中异硫氰酸盐含量的比较研究表明，除了每100克近300毫克的乙烯基硫代恶唑烷酮外，油菜籽还含有近200 - 300毫克/100克的异硫氰酸盐，其中3-丁烯基异硫氰酸盐和4-戊烯基异硫氰酸盐（比例为4:1）是主要成分，薄层色谱法和气相色谱法已证实这一点。压榨菜籽油中仅发现约1毫克/100克的异硫氰酸盐；而在萃取菜籽油中约为10毫克/100克。3-丁烯基异硫氰酸盐和4-戊烯基异硫氰酸盐（比例为4:1）再次成为主要成分。油中未检测到硫代甘油酯。乙烯基硫代恶唑烷酮仅在萃取菜籽油中发现（约2毫克/100克）。
