Due to the side effects of obesity medications, many studies have focused on the natural products used in the daily diet to control weight. Moringa seed pods and leaves are widely used as vegetables or diet supplements due to the high nutrition value. However, no bioactivity-guided anti-adipogenic study was previously conducted. Therefore, a preadipocyte cell line was adopted as the bioactivity assay to identify the anti-adipogenic compounds in the peeled Moringa seed. Two known sulphur-containing compounds (1 and 2) were isolated and identified. Compound 2, 4-(alpha -l-rhamnosyloxy) benzyl isothiocyanate, showed a great anti-adipogneic effect with an IC50 value of 9.2 mu g/mL. The isothiocyanate (ITC) group in compound 2 could be responsible for the inhibitory activity. In addition, a series of compounds with the ITC group were used to further investigate the structure-activity relationship, indicating foods containing ITC derivatives have the potential of being used to control weight.
