Abstract This paper measured and analyzed the component and content of glucosinolates in Chinese kale plants treated by sodium selenite of different concentration by HPLC．The results showed that the leaves and roots of overground parts broccoli contained 9 and 8 kinds of glucosides，respectively．They belonged to aliphatic glucosinolates and indole glucosinolates．No aromatic glucosinolates was detected．The effects of treatments by different sodium selenite concentration on the total glucosinolates，aliphatic glucosinolates and indole glucosinolates contents in different parts of Chinese kale plants were different．Most of them reached the highest value under the treatment of 5 μmol · L-1 sodium selenite．The incidence of treatments by different sodium selenite concentration on the constituent contents of various glucosinolates in overgound plant parts are bigger than in roots．
