Abstract
The seeds of Raphanus sativus L., known as Lai-fu-zi in traditional Chinese Medicine, are always roasted before clinical use for avoiding nausea. During an investigation of the chemical difference between roasted and pre-roasted products, two novel sulfur-containing compounds, which mainly existed in the pre-roasted products, were isolated. Their structures and absolute configurations were established by spectroscopic and X-ray diffraction analysis.
