- Abstract
- Isothiocyanates in Brassica exhibit anticancer properties related to induction of phase II detoxification enzymes. Currently, variations of isothiocyanates was evaluated in Baemuchae (XBrassicoraphanus), which was newly generated by inter-specific hybrid crops between radish (Raphanus sativus L.) and Chinese cabbage (Brassica campestris L. ssp. pekinensis). A high-performance liquid chromatography system coupled with an evaporative light scattering detector and gas chromatography-mass spectrometry were utilised to identify and quantify isothiocyanates including sulforaphene and sulforaphane in prepared plants. Sulforaphene constituted a major isothiocyanate in Baemuchae and radish, while sulforaphane was detected in broccoli. Sulforaphane contents varied during broccoli growth, with a constant decrease noted from 144.9 +/- 8.69 in sprouts to 8.1 +/- 1.07 mu g g(-1) in young leaves. Sulforaphene contents in Baemuchae and radish sprouts were 172.6 +/- 11.23 and 131.3 +/- 4.08 mu g g(-1), respectively, and were rarely a. ected by plant growth. The result supported that newly generated crop Baemuchae had potential to be utilised as functional material because of presence of sulforaphene.
